开启Android辅助功能 Accessibility Services

• 在root模式下自动开启辅助服务，执行命令

settings put secure enabled_accessibility_services com.example.app/.ExampleService
settings put secure accessibility_enabled 1

但是，这样做其他已经开启的辅助服务会关闭，在/data/system/users/0/settings_secure.xml 目录下保存着所有已开启的Accessibility Services，因此要同时开启多个Accessibility Services可以加“:”做拼接

settings put secure enabled_accessibility_services com.example.app/.ExampleService1:com.example.app/.ExampleService2
settings put secure accessibility_enabled 1

• 利用代码

//申请权限
<uses-permission android:name="android.permission.WRITE_SETTINGS" />
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" />

//设置代码
fun startAccessServices(serviceName: String, callback: () -> Unit) {
Settings.Secure.putString(getContentResolver(),
Settings.Secure.ENABLED_ACCESSIBILITY_SERVICES, "packageName/serviceName")
Settings.Secure.putString(getContentResolver(),
Settings.Secure.ACCESSIBILITY_ENABLED, "1")
}
