# ShPref-Library

Simplifies the interaction with Shared Preferences on Android. (Bonus: Logger)

# Installation

- Add the dependency from jCenter to your app's (not project) build.gradle file:

```sh
repositories {
    jcenter()
}

dependencies {
    implementation 'net.alexandroid.utils:shpref:1.7' // Java version
    implementation 'net.alexandroid.utils:shprefkt:1.7' // Kotlin version
}
```

- Add init line in your application class as shown below:

```sh
public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        ShPref.init(this, ShPref.APPLY); // Java

ShPrefKt shpref = ShPrefKt(this); // Kotlin
    }
}
```

* Also don't forget to add: android:name=".MyApplication" at your application tag in AndroidManifest.xml
```sh
 <application
 android:name=".MyApplication"
 ...>
```

# How to use it

On initialization (at yours application class) you should pass default saving mode as a second argument. 
As you know, there are two options to save: APPLY (faster and asynchronous) or COMMIT.

With ShPref library you can use following types: String, int, boolean, float, double, long and lists with that types.
 
- Put:
 
```sh
// Save using a resource as a key
ShPref.put(R.string.some_key, "Sample text");

// Save using a hard coded string
ShPref.put("HardCodedKey", 25);

// Option to chain using Editor class
new ShPref.Editor()
    .put("key1", "key1value")
    .put("key2", "key2value")
    .put("key3", "key3value")
    .commit();

// Saving a List
ArrayList<Integer> list = new ArrayList<>();
for (int i = 0; i < 10; i++) {
 list.add(i);
}
ShPref.putList("myListKey", list); 
```

- Get:
 
```sh
// Get a value and if it not exist get a default value that was passed as a second argument
String myString = ShPref.getString(R.string.some_key, "Default value");
int myInt= ShPref.getInt("HardCodedKey", 0); // 0 is default value

// Get values without to set default values (if not exist: getString return null, getBoolena return false and other 0)
String myString = ShPref.getString(R.string.some_key);
int myInt= ShPref.getInt("HardCodedKey");

// Get value as an object
Object obj = ShPref.get(R.string_some_key); //excluding double

// Get a list
 List<Integer> list = ShPref.getListOfIntegers("myListKey");
```

- Contains:
 
```sh
// Checking for existence
boolean isContains = ShPref.contains(R.string.key_key);
```

- Remove:
 
```sh
ShPref.remove(R.string.key_key);
ShPref.remove("HardCodedKey");
```

- Clear:
 
```sh
// Remove all values from the preferences.
ShPref.clear();
```

- Mode forcing methods: 
For example if you have choosen as default APPLY mode and you need to save or remove something using COMMIT there are special methods for that case:
```sh
putC(); removeC(); // Force commit
putA(); removeA(); // Force apply
```
 
# Bonus

Option to get application Context from anywhere:
```sh
Context appContext = Contextor.getInstance().getContext();
```
