在Xamarin中使用AccessibilityService类打开飞行模式

<service android:name=".MyAccessibilityService"
    android:permission="android.permission.BIND_ACCESSIBILITY_SERVICE">
    <intent-filter>
        <action android:name="android.accessibilityservice.AccessibilityService" />
    </intent-filter>
    <meta-data
        android:name="android.accessibilityservice"
        android:resource="@xml/accessibility_service_config" />
</service>

<accessibility-service xmlns:android="http://schemas.android.com/apk/res/android"
    android:accessibilityEventTypes="typeAllMask"
    android:accessibilityFlags="flagDefault"
    android:accessibilityFeedbackType="feedbackGeneric"
    android:canRetrieveWindowContent="true"
    android:description="@string/accessibility_service_description"
    android:notificationTimeout="100"
    android:packageNames="com.example.app"
    android:settingsActivity="com.example.app.SettingsActivity" />

public override void OnAccessibilityEvent(AccessibilityEvent e)
{
    // 判断当前界面是否是需要打开飞行模式的界面
    if (e.PackageName == "com.example.app" && e.EventType == AccessibilityEventType.WindowStateChanged)
    {
        // 执行打开飞行模式的操作
        var settingsIntent = new Intent(Android.Provider.Settings.ActionAirplaneModeSettings);
        settingsIntent.AddFlags(ActivityFlags.NewTask);
        Application.Context.StartActivity(settingsIntent);
    }
}

public override void OnServiceConnected()
{
    // 进行一些初始化操作
}
