# DroidCast_raw

本项目修改自 [DroidCast](https://github.com/rayworks/DroidCast) ，是为 [AzurLaneAutoScript](https://github.com/LmeSzinc/AzurLaneAutoScript) 提供的一个能够在 Android 设备上面截取屏幕并**返回 Bitmap** 的工具。

⚠️ 代码中通过反射调用了一些系统隐藏的方法，相关功能可能会随着 Android 系统接口的变化而受到影响。

当前该工具支持从SDK 23(Android 6.0) 至 SDK34(Android 14)的屏幕截图获取。

## 依赖

- [Python 3.6+](https://www.python.org/downloads/)（可选）

- [ADB Tools](https://developer.android.google.cn/studio/releases/platform-tools)

## 快速上手

- 连接你的 Android 设备或模拟器

- 安装 APK

```shell
adb install DroidCast_raw-release-1.0.apk
```

- 运行脚本

> 默认运行在 53516 端口上

```shell
python scripts/automation.py
```

> 你可以通过附加参数 ```-h``` 来获取帮助，如```python scripts/automation.py -h```

随后，默认浏览器将会打开，展示屏幕截图。

- （可选）指定截屏服务端口

```shell
python scripts/automation.py -p 8080
```

## 手动运行

> 注：安装 APK 后，你可以使用脚本来自动化完成以下操作

### 方法一（需要安装 APK）

- 安装 APK

```shell
adb install DroidCast_raw-release-1.0.apk
```

- 获取 ```CLASSPATH```

```shell
adb shell pm path ink.mol.droidcast_raw
```

返回的 ```package:``` 后面的内容即为 ```CLASSPATH=``` 后的内容

- 通过 ```app_process``` 启动内部的图片处理服务进程

```shell
adb shell CLASSPATH=*** app_process / ink.mol.droidcast_raw.Main
```

> ```***``` 为上一步获取的 ```package:``` 后面的内容

> 如获取到的结果为 ```package:/data/app/~~nmfieV3qg8e0Mju_KptQRg==/ink.mol.droidcast_raw-II4YPHI93Nl0kjdPC4D6Vg==/base.apk```

> 需要执行的命令就为 ```adb shell CLASSPATH=/data/app/~~nmfieV3qg8e0Mju_KptQRg==/ink.mol.droidcast_raw-II4YPHI93Nl0kjdPC4D6Vg==/base.apk app_process / ink.mol.droidcast_raw.Main```

- 使用 ```adb forward``` 命令将本地（PC）socket 连接重定向到已连接的 Android 设备上

```shell
adb forward tcp:53516 tcp:53516
```

此时可打开 ```http://127.0.0.1:53516/preview``` 获取截图

### 方法二（无需安装 APK）

- 将 apk 文件 push 到手机的 tmp 文件夹下

```
adb push DroidCast_raw-release-1.0.apk /data/local/tmp
```

- 通过 app_process 启动内部的图片处理服务进程

```shell
adb shell CLASSPATH=/data/local/tmp/DroidCast_raw-release-1.0.apk app_process / ink.mol.droidcast_raw.Main (--port=8080)
```
> 注： 在某些设备上, 如果碰到类似 ```appproc: ERROR: could not find class 'ink.mol.droidcast_raw.Main'``` 的错误，请改用方法一。

- 使用 ```adb forward``` 命令将本地（PC）socket 连接重定向到已连接的 Android 设备上

```shell
adb forward tcp:53516 tcp:53516
```

此时可打开 ```http://127.0.0.1:53516/preview``` 查看截图或者按指定的图片大小和类型查看，如 ```http://127.0.0.1:53516/preview?width=1080&height=1920```

## 数据返回
```shell
GET http://ip:port/screenshot(?width=xxx&height=xxx)
返回 BitmapByteArray(RGB_565) ContentType="application/octet-stream"
```

```shell
GET http://ip:port/preview(?width=xxx&height=xxx)
返回 ByteArrayOutputStream ContentType="image/png"
```
