## What is CrashX?

CrashX is an Android library that catches uncaught Java/Kotlin exceptions and opens a custom error screen instead of immediately showing the default Android crash dialog.

It helps developers provide a better crash recovery experience by allowing users to restart the app, close the app, view technical details, copy crash information, or share a crash report.

CrashX is useful when you want to:

- Show a professional crash screen instead of the default system crash dialog.
- Let users restart the app safely after an unexpected crash.
- Let users close the app cleanly.
- Show or hide technical crash details based on your build type.
- Share crash reports through email or Android share sheet.
- Add a support email for crash reporting.
- Customize title, message, icon, colors, and button labels.
- Display a unique crash ID on the crash screen.
- Include app version, CrashX version, Android version, API level, device name, brand, manufacturer, crash date, thread name, and stack trace in reports.
- Track recent Activity lifecycle events before the crash.
- Prevent infinite crash restart loops.
- Keep your open-source attribution and licensing transparent.

---

## Why CrashX?

Even well-tested apps can crash because of device-specific behavior, third-party SDK issues, network edge cases, unexpected null values, database errors, lifecycle timing issues, or unhandled exceptions.

The default Android crash dialog is generic and does not help users recover. CrashX gives your app a controlled, branded, and more professional fallback experience.

| Default Android crash | CrashX |
|---|---|
| Generic system crash dialog | Branded custom crash screen |
| No custom recovery UI | Restart and close buttons |
| No friendly explanation | Custom title and message |
| No simple reporting flow | Optional report/share button |
| No custom metadata | Crash ID, app info, device info, thread, stack trace |
| No UI control | Fully configurable colors and labels |
| Poor user experience | Professional recovery screen |

## Sample screen

## Installation

CrashX is available through **Maven Central**.

JitPack is also supported as an alternative installation source.

---

### Option 1: Maven Central

Maven Central is the recommended installation method.

### Step 1: Add Maven Central repository

#### Gradle Kotlin DSL

Add this in your root `settings.gradle.kts`:

```kotlin
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
````

#### Gradle Groovy DSL

Add this in your root `settings.gradle`:

```gradle
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
    }
}
```

For older Gradle projects, add this in your root `build.gradle`:

```gradle
allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
```

---

### Step 2: Add CrashX dependency

Add this in your app module `build.gradle` file.

#### Gradle Kotlin DSL

```kotlin
dependencies {
    implementation("io.github.tutorialsandroid:crashx:7.0.1")
}
```

#### Gradle Groovy DSL

```gradle
dependencies {
    implementation 'io.github.tutorialsandroid:crashx:7.0.1'
}
```

---

### Option 2: JitPack

Use JitPack only if you want to install CrashX directly from the GitHub release tag.

### Step 1: Add JitPack repository

#### Gradle Kotlin DSL

Add this in your root `settings.gradle.kts`:

```kotlin
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven("https://jitpack.io")
    }
}
```

#### Gradle Groovy DSL

Add this in your root `settings.gradle`:

```gradle
dependencyResolutionManagement {
    repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
```

For older Gradle projects, add this in your root `build.gradle`:

```gradle
allprojects {
    repositories {
        google()
        mavenCentral()
        maven { url 'https://jitpack.io' }
    }
}
```

---

### Step 2: Add CrashX JitPack dependency

Add this in your app module `build.gradle` file.

#### Gradle Kotlin DSL

```kotlin
dependencies {
    implementation("com.github.TutorialsAndroid:crashx:v7.0.1")
}
```

#### Gradle Groovy DSL

```gradle
dependencies {
    implementation 'com.github.TutorialsAndroid:crashx:v7.0.1'
}
```

---

### Minimum SDK

CrashX v7.X.X is designed for modern Android projects.

```gradle
android {
    defaultConfig {
        minSdk 23
    }
}
```

---

## Quick start

CrashX installs automatically through its initialization provider.

After adding the dependency, force a test crash:

```java
throw new RuntimeException("Test CrashX crash");
```

Your app should open the CrashX error screen instead of showing only the default Android crash dialog.

---

## Basic configuration

It is recommended to configure CrashX inside your `Application` class so the configuration is ready as early as possible.

```java
import android.app.Application;

import com.developer.crashx.config.CrashConfig;

public class MyApplication extends Application {

@Override
    public void onCreate() {
        super.onCreate();

CrashConfig.Builder.create()
                .backgroundMode(CrashConfig.BACKGROUND_MODE_SHOW_CUSTOM)
                .enabled(true)
                .showErrorDetails(true)
                .showRestartButton(true)
                .showCloseButton(true)
                .trackActivities(true)
                .apply();
    }
}
```

```xml
<application
 android:name=".MyApplication"
 android:allowBackup="true"
 android:theme="@style/AppTheme">

</application>
```

---

## Full professional v7.X.X configuration

This example uses most of the new v7.X.X features.

```java
CrashConfig.Builder.create()
        .backgroundMode(CrashConfig.BACKGROUND_MODE_SHOW_CUSTOM)
        .enabled(true)

// Core crash behavior
        .showErrorDetails(true)
        .showRestartButton(true)
        .showCloseButton(true)
        .showReportButton(true)
        .showCopyButtonInDetails(true)
        .logErrorOnRestart(true)
        .trackActivities(true)
        .minTimeBetweenCrashesMs(3000)

// Crash screen text
        .errorTitle("Oops! The app crashed")
        .errorMessage("Something unexpected happened. Please restart the app or send a crash report to help us fix it.")
        .restartButtonText("Restart app")
        .closeButtonText("Close app")
        .detailsButtonText("View technical details")
        .reportButtonText("Send crash report")
        .copyButtonText("Copy details")

// Crash report options
        .supportEmail("support@example.com")
        .reportSubject("Crash report from my Android app")
        .reportChooserTitle("Send crash report using")
        .additionalReportInfo("Environment: Production")

// Visibility and report metadata
        .showCrashId(true)
        .showAppInfo(true)
        .includeDeviceInfo(true)
        .includeActivityLog(true)
        .includeStackTrace(true)
        .includeBuildDate(true)
        .includeCrashId(true)
        .crashIdPrefix("CRASHX")

// Limits
        .maxActivityLogEntries(50)
        .maxStackTraceSize(128 * 1024)

// UI colors
        .backgroundColor(0xFFB91C1C)
        .cardBackgroundColor(0xFFFFFFFF)
        .primaryButtonColor(0xFFB91C1C)
        .secondaryButtonColor(0xFFF3F4F6)
        .titleTextColor(0xFF111827)
        .messageTextColor(0xFF4B5563)
        .buttonTextColor(0xFFFFFFFF)
        .secondaryButtonTextColor(0xFF111827)
        .metaTextColor(0xFF6B7280)

// Optional custom restart target
        .restartActivity(MainActivity.class)

.apply();
```

---

## Configuration

CrashX can be customized using `CrashConfig.Builder`.

### Background behavior

```java
.backgroundMode(CrashConfig.BACKGROUND_MODE_SHOW_CUSTOM)
```

Available modes:

| Mode | Description |
|---|---|
| `BACKGROUND_MODE_SHOW_CUSTOM` | Shows the CrashX error screen even if the app crashes in background. |
| `BACKGROUND_MODE_CRASH` | Lets the default/original uncaught exception handler handle background crashes. |
| `BACKGROUND_MODE_SILENT` | Silently closes the app when it crashes in background. |

---

### Enable or disable CrashX

```java
.enabled(true)
```

Use this if you want to enable or disable CrashX depending on build type, flavor, or environment.

Example:

```java
CrashConfig.Builder.create()
        .enabled(!BuildConfig.DEBUG)
        .apply();
```

---

### Show error details

```java
.showErrorDetails(true)
```

When enabled, CrashX shows a button that allows users or testers to view technical crash details.

For production apps, you may prefer:

```java
.showErrorDetails(false)
```

---

### Show restart button

```java
.showRestartButton(true)
```

When enabled, the default error screen shows a restart button.

If no restart activity is configured, CrashX will try to find your launcher activity automatically.

---

### Show close button

```java
.showCloseButton(true)
```

When enabled, the default error screen shows a close button so the user can exit the app cleanly.

---

### Show report button

```java
.showReportButton(true)
```

When enabled, CrashX shows a report/share button on the crash screen.

You can combine it with:

```java
.supportEmail("support@example.com")
.reportSubject("Crash report")
.reportChooserTitle("Send crash report using")
```

---

### Show copy button in details dialog

```java
.showCopyButtonInDetails(true)
```

When enabled, the error details dialog includes a copy action so the crash report can be copied to the clipboard.

---

### Log error on restart

```java
.logErrorOnRestart(true)
```

When enabled, CrashX logs the previous crash stack trace again when the crash activity opens.

This is useful because the crash screen runs in a new process and Android Studio Logcat may otherwise switch away from the original crashing process.

---

### Track Activity lifecycle

```java
.trackActivities(true)
```

When enabled, CrashX records recent Activity lifecycle events before the crash.

Example activity log:

```txt
2026-05-25 14:10:01: MainActivity created
2026-05-25 14:10:02: MainActivity resumed
2026-05-25 14:10:15: ProfileActivity created
2026-05-25 14:10:16: ProfileActivity resumed
```

This can help you understand what the user was doing before the crash.

---

### Limit Activity lifecycle log size

```java
.maxActivityLogEntries(50)
```

CrashX v7.X.X uses a bounded Activity log queue, so the log does not grow forever.

---

### Crash loop protection

```java
.minTimeBetweenCrashesMs(3000)
```

CrashX prevents infinite crash loops by checking if the app crashed recently.

If another crash occurs within the configured time, CrashX avoids repeatedly opening the custom crash screen.

---

### Stack trace trim size

```java
.maxStackTraceSize(128 * 1024)
```

Use this to control the maximum stack trace size passed to the crash screen.

---

### Custom error image

```java
.errorDrawable(R.drawable.ic_crash)
```

Use this to replace the default crash icon.

---

### Custom restart activity

```java
.restartActivity(MainActivity.class)
```

CrashX opens this activity when the user taps the restart button.

If not provided, CrashX tries to find your restart activity by intent filter, and then falls back to your launcher activity.

---

### Custom error activity

```java
.errorActivity(MyCrashActivity.class)
```

Use this when you want a completely custom crash screen instead of the default CrashX UI.

---

### Event listener

```java
.eventListener(new MyCrashEventListener())
```

Use this to track crash-screen events.

```java
public class MyCrashEventListener implements CrashActivity.EventListener {

@Override
    public void onLaunchErrorActivity() {
        // Called when CrashX opens the error screen
    }

@Override
    public void onRestartAppFromErrorActivity() {
        // Called when the user restarts the app
    }

@Override
    public void onCloseAppFromErrorActivity() {
        // Called when the user closes the app
    }
}
```

Important: the listener must not be an anonymous or non-static inner class because it needs to be serializable.

---

## UI customization

CrashX v7.X.X allows direct UI customization from Java configuration.

### Custom text

```java
.errorTitle("Oops! Something went wrong")
.errorMessage("The app ran into an unexpected problem. Please restart the app.")
.restartButtonText("Restart now")
.closeButtonText("Close")
.detailsButtonText("Technical details")
.reportButtonText("Send report")
.copyButtonText("Copy details")
```

### Custom colors

```java
.backgroundColor(0xFF111827)
.cardBackgroundColor(0xFFFFFFFF)
.primaryButtonColor(0xFF2563EB)
.secondaryButtonColor(0xFFF3F4F6)
.titleTextColor(0xFF111827)
.messageTextColor(0xFF4B5563)
.buttonTextColor(0xFFFFFFFF)
.secondaryButtonTextColor(0xFF111827)
.metaTextColor(0xFF6B7280)
```

### Crash ID display

```java
.showCrashId(true)
.crashIdPrefix("CRASHX")
```

CrashX generates a unique crash ID for each crash. This helps developers match user reports with logs.

### App info display

```java
.showAppInfo(true)
```

When enabled, the default crash screen can display app and crash metadata such as app version and CrashX version.

---

## Crash report sharing

CrashX v7.X.X can show a report button and prepare a shareable crash report.

```java
.showReportButton(true)
.supportEmail("support@example.com")
.reportSubject("Crash report from my Android app")
.reportChooserTitle("Send crash report using")
.additionalReportInfo("Environment: Production")
```

If `supportEmail()` is provided, CrashX prepares an email-style report. If no support email is provided, the user can still share the report through available Android share apps.

---

## Crash report data

CrashX can include the following information in the generated report:

| Data | Description |
|---|---|
| Crash ID | Unique ID generated for the crash |
| Package name | App package identifier |
| App version | Installed app version |
| CrashX version | CrashX library version |
| Android version | Android release version |
| API level | Android SDK level |
| Device model | Device model name |
| Brand | Device brand |
| Manufacturer | Device manufacturer |
| Crash date | Date and time of crash |
| Crash thread | Thread where the crash happened |
| Throwable class | Exception class name |
| Throwable message | Exception message |
| Build date | App build date when available |
| Stack trace | Java/Kotlin exception stack trace |
| Activity log | Recent Activity lifecycle events |
| Additional report info | Custom developer-defined report text |

You can control what gets included:

```java
.includeDeviceInfo(true)
.includeActivityLog(true)
.includeStackTrace(true)
.includeBuildDate(true)
.includeCrashId(true)
.additionalReportInfo("Environment: Production")
```

---

## Recommended configurations

### Debug build

Use this while developing and testing.

```java
CrashConfig.Builder.create()
        .enabled(true)
        .showErrorDetails(true)
        .showRestartButton(true)
        .showCloseButton(true)
        .showReportButton(true)
        .showCopyButtonInDetails(true)
        .trackActivities(true)
        .includeDeviceInfo(true)
        .includeActivityLog(true)
        .includeStackTrace(true)
        .includeBuildDate(true)
        .includeCrashId(true)
        .errorTitle("Debug crash")
        .errorMessage("CrashX caught this crash in debug mode. Open details to inspect the stack trace.")
        .apply();
```

### Production build

Use this for public apps where you want a clean user experience.

```java
CrashConfig.Builder.create()
        .enabled(true)
        .showErrorDetails(false)
        .showRestartButton(true)
        .showCloseButton(true)
        .showReportButton(true)
        .showCopyButtonInDetails(false)
        .trackActivities(false)
        .includeDeviceInfo(true)
        .includeActivityLog(false)
        .includeStackTrace(true)
        .includeBuildDate(true)
        .includeCrashId(true)
        .supportEmail("support@example.com")
        .errorTitle("Something went wrong")
        .errorMessage("The app ran into an unexpected problem. Please restart the app or report the issue.")
        .apply();
```

### Minimal configuration

Use this if you only want a clean restart screen.

```java
CrashConfig.Builder.create()
        .enabled(true)
        .showErrorDetails(false)
        .showRestartButton(true)
        .showCloseButton(true)
        .showReportButton(false)
        .trackActivities(false)
        .apply();
```

---

## Custom error activity

If you want complete control, create your own crash activity.

```java
public class MyCrashActivity extends AppCompatActivity {

private CrashConfig config;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_crash);

config = CrashActivity.getConfigFromIntent(getIntent());

String crashId = CrashActivity.getCrashIdFromIntent(getIntent());
        String stackTrace = CrashActivity.getStackTraceFromIntent(getIntent());
        String activityLog = CrashActivity.getActivityLogFromIntent(getIntent());
        String threadName = CrashActivity.getThreadNameFromIntent(getIntent());
        String throwableClass = CrashActivity.getThrowableClassFromIntent(getIntent());
        String throwableMessage = CrashActivity.getThrowableMessageFromIntent(getIntent());
        String crashDate = CrashActivity.getCrashDateFromIntent(getIntent());
        String fullDetails = CrashActivity.getAllErrorDetailsFromIntent(this, getIntent());

findViewById(R.id.btnRestart).setOnClickListener(v -> {
            CrashActivity.restartApplication(this, config);
        });

findViewById(R.id.btnClose).setOnClickListener(v -> {
            CrashActivity.closeApplication(this, config);
        });
    }
}
```

```xml
<activity
 android:name=".MyCrashActivity"
 android:process=":error_activity"
 android:exported="false" />
```

Then apply it:

```java
CrashConfig.Builder.create()
        .errorActivity(MyCrashActivity.class)
        .apply();
```

---

## Intent filter based setup

You can define the error activity using an intent filter.

```xml
<activity
 android:name=".MyCrashActivity"
 android:process=":error_activity"
 android:exported="false">

<intent-filter>
 <action android:name="com.developer.crashx.ERROR" />
 <category android:name="android.intent.category.DEFAULT" />
 </intent-filter>

</activity>
```

You can define the restart activity like this:

```xml
<activity
 android:name=".MainActivity"
 android:exported="true">

<intent-filter>
 <action android:name="com.developer.crashx.RESTART" />
 <category android:name="android.intent.category.DEFAULT" />
 </intent-filter>

</activity>
```

---

## Useful methods for custom screens

### Get stack trace

```java
String stackTrace = CrashActivity.getStackTraceFromIntent(getIntent());
```

### Get activity lifecycle log

```java
String activityLog = CrashActivity.getActivityLogFromIntent(getIntent());
```

### Get crash ID

```java
String crashId = CrashActivity.getCrashIdFromIntent(getIntent());
```

### Get crash thread name

```java
String threadName = CrashActivity.getThreadNameFromIntent(getIntent());
```

### Get throwable class

```java
String throwableClass = CrashActivity.getThrowableClassFromIntent(getIntent());
```

### Get throwable message

```java
String throwableMessage = CrashActivity.getThrowableMessageFromIntent(getIntent());
```

### Get crash date

```java
String crashDate = CrashActivity.getCrashDateFromIntent(getIntent());
```

### Get full error details

```java
String details = CrashActivity.getAllErrorDetailsFromIntent(this, getIntent());
```

### Get crash config

```java
CrashConfig config = CrashActivity.getConfigFromIntent(getIntent());
```

### Restart application

```java
CrashActivity.restartApplication(this, config);
```

### Restart application with custom intent

```java
Intent intent = new Intent(this, MainActivity.class);
CrashActivity.restartApplicationWithIntent(this, intent, config);
```

### Close application

```java
CrashActivity.closeApplication(this, config);
```

---

## Testing CrashX

You can force a simple crash:

```java
throw new RuntimeException("CrashX test crash");
```

You can test a delayed crash:

```java
new Handler(Looper.getMainLooper()).postDelayed(() -> {
    throw new RuntimeException("CrashX delayed crash test");
}, 3000);
```

You can test a null pointer crash:

```java
String value = null;
int length = value.length();
```

After the crash, verify:

- Crash screen opens.
- Restart button launches the app again.
- Close button exits the app.
- Error details open when enabled.
- Copy button works when enabled.
- Report button opens share/email options when enabled.
- Crash ID appears when enabled.
- Device/app metadata appears in the report when enabled.
- Activity lifecycle log appears when tracking is enabled.

---

## Using with Firebase Crashlytics, ACRA, or other crash tools

CrashX can be used with crash reporting tools, but initialization order matters.

If another library also uses `Thread.setDefaultUncaughtExceptionHandler`, initialize CrashX first, then initialize your crash reporting SDK.

Recommended order:

```java
@Override
public void onCreate() {
    super.onCreate();

CrashConfig.Builder.create()
            .enabled(true)
            .apply();

// Initialize Firebase Crashlytics, ACRA, or another crash tool after CrashX if needed.
}
```

If a custom crash handler replaces CrashX and does not call the previous handler, CrashX may not receive crashes.

## R8 / ProGuard

CrashX usually does not require special ProGuard rules.

If you use a custom error activity or custom event listener and your app has aggressive shrinking enabled, you can keep those classes:

```proguard
-keep class your.package.MyCrashActivity { *; }
-keep class your.package.MyCrashEventListener { *; }
```

CrashX also includes consumer rules for safer library usage.

## Privacy and production recommendations

Crash reports may contain technical information such as stack traces, app version, device model, package name, Activity names, and exception messages.

For production apps:

- Avoid showing raw stack traces to normal users unless needed.
- Use `.showErrorDetails(false)` for public builds if technical details are sensitive.
- Use a support email controlled by your team.
- Do not collect or share personal user data without permission.
- Avoid adding sensitive information to `additionalReportInfo()`.
- Clearly explain crash reporting behavior in your app privacy policy if reports are sent externally.

Recommended production setup:

```java
CrashConfig.Builder.create()
        .enabled(true)
        .showErrorDetails(false)
        .showReportButton(true)
        .supportEmail("support@example.com")
        .includeDeviceInfo(true)
        .includeActivityLog(false)
        .includeStackTrace(true)
        .includeCrashId(true)
        .apply();
```

---

## Limitations

CrashX is designed for uncaught Java/Kotlin exceptions.

CrashX does not handle every possible failure. It does not catch:

- ANRs
- Native crashes
- Low-level system kills
- Force stops by the operating system
- Crashes before the library is initialized
- Some multiprocess edge cases
- Errors inside the crash activity itself

CrashX improves the crash recovery experience, but it is not a replacement for proper crash monitoring, logging, testing, and bug fixing.

## Migration guide for v7.0.1

### 1. Update dependency

```gradle
implementation 'com.github.TutorialsAndroid:crashx:v7.0.1'
```

### 2. Add attribution files

Make sure your repository includes:

```txt
LICENSE
NOTICE
README.md
```

### 3. Review package imports

```java
import com.developer.crashx.CrashActivity;
import com.developer.crashx.config.CrashConfig;
```

### 4. Replace upgraded source files

For the v7.0.1 upgrade, replace these files in the library module:

```txt
library/src/main/java/com/developer/crashx/CrashActivity.java
library/src/main/java/com/developer/crashx/config/CrashConfig.java
library/src/main/java/com/developer/crashx/activity/DefaultErrorActivity.java
library/src/main/java/com/developer/crashx/provider/CrashInitProvider.java
library/src/main/AndroidManifest.xml
library/src/main/res/layout/crash_default_error_activity.xml
library/src/main/res/values/strings.xml
library/src/main/res/values/dimens.xml
library/src/main/res/drawable/crash_ic_bug_report.xml
library/consumer-rules.pro
```

### 5. Update configuration

Old basic setup:

```java
CrashConfig.Builder.create()
        .showErrorDetails(true)
        .trackActivities(true)
        .apply();
```

New v7 recommended setup:

```java
CrashConfig.Builder.create()
        .showErrorDetails(true)
        .showRestartButton(true)
        .showCloseButton(true)
        .trackActivities(true)
        .errorTitle("Oops! The app crashed")
        .errorMessage("Something unexpected happened. Please restart the app.")
        .showReportButton(true)
        .supportEmail("support@example.com")
        .includeDeviceInfo(true)
        .includeActivityLog(true)
        .includeStackTrace(true)
        .includeCrashId(true)
        .apply();
```

### 6. Test crash screen

```java
throw new RuntimeException("CrashX v7.0.1 migration test");
```

- `README.md` uses `v7.0.1` everywhere.
- GitHub release tag is exactly `v7.0.1`.
- JitPack dependency points to `com.github.TutorialsAndroid:crashx:v7.0.1`.
- `CrashActivity.VERSION` is `7.0.0`.
- `NOTICE` file exists.
- Apache 2.0 license exists.
- Original CustomActivityOnCrash attribution is visible.
- Sample app compiles.
- Library module builds successfully.
- Restart button works.
- Close button works.
- Details dialog works.
- Copy button works.
- Report/share button works.
- Crash ID appears when enabled.
- Production config hides technical details when required.

## Relationship with CustomActivityOnCrash

CrashX started from CustomActivityOnCrash and now continues as a credited derivative project.

The original project solved the core idea of showing a custom crash activity instead of the default Android crash dialog.

CrashX builds on that idea with:

- Modern Android maintenance
- Updated documentation
- UI customization
- Crash report sharing
- Crash IDs
- Safer configuration
- Activity log improvements
- Crash metadata improvements
- Updated default UI
- Clear attribution and licensing

Original project: https://github.com/Ereza/CustomActivityOnCrash
