Android:使用TYPE_APPLICATION_OVERLAY拒绝窗口类型2038的权限

问题描述 投票:15回答:5

我试图创建一个高于其他应用程序的视图:

WindowManager.LayoutParams paramsDirectorView = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
        WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

我查看了其他回复,发现了以下“绘制应用程序”的内容:

  • 我在清单中有android.permission.SYSTEM_ALERT_WINDOW
  • 我正在进行Settings.canDrawOverlays(this)检查,返回true。
  • 我做了一切位于这里permission denied for window type

我仍然得到“ - 窗口类型2038的权限被拒绝”错误。截至目前我正在使用TYPE_PHONE并且它可以工作,但它已被弃用并且说要使用TYPE_APPLICATION_OVERLAY。有人可以对此进行跟进,因为TYPE_PHONE答案不是真正的解决方案,而是Android O中不推荐使用的“补丁工作”解决方案。

我在Android 7.1.2上运行

我有完全相同的问题。我想你应该区分目标(奥利奥之前和之后)

int LAYOUT_FLAG;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
     LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
} else {
        LAYOUT_FLAG = WindowManager.LayoutParams.TYPE_PHONE;
}

params = new WindowManager.LayoutParams(
        WindowManager.LayoutParams.WRAP_CONTENT,
        WindowManager.LayoutParams.WRAP_CONTENT,
        LAYOUT_FLAG,
        WindowManager.LayoutParams.FLAG_NOT_TOUCHABLE | WindowManager.LayoutParams.FLAG_LAYOUT_IN_SCREEN | WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
        PixelFormat.TRANSLUCENT);

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

我在服务类(Marshmallow之前和之后)有完全相同的问题。

if (Build.VERSION.SDK_INT >= 23) {
    if (!Settings.canDrawOverlays(this)) {
        Intent intent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
          Uri.parse("package:" + getPackageName()));
        startActivityForResult(intent, 1234);
    }
} else {
    startService(new Intent(SplashActivity.this,                     
    CheckServicesForApps.class));
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == 1234) {
            startService(new Intent(SplashActivity.this, 
            CheckServicesForApps.class));

    }
}

public class CheckServicesForApps extends Service {
    private Context context = null;

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

        ImageView imageView = new ImageView(context);
        imageView.setVisibility(View.GONE);

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            try {
                windowManager = (WindowManager)getSystemService(WINDOW_SERVICE);

                //here is all the science of params
                final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                        WindowManager.LayoutParams.WRAP_CONTENT,
                        WindowManager.LayoutParams.WRAP_CONTENT,
                        WindowManager. LayoutParams.TYPE_SYSTEM_ERROR,
                        WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED
                                | WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON
                                | WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON,
                        PixelFormat.TRANSLUCENT
                );

                windowManager.addView(imageView, params);
                hand=new Handler();

            } catch (Exception e) {
                hand=new Handler();
                e.printStackTrace();
            }
        }else{
            windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);

            final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
                    WindowManager.LayoutParams.WRAP_CONTENT,
                    WindowManager.LayoutParams.WRAP_CONTENT,
                    WindowManager.LayoutParams.TYPE_PHONE,

            params.gravity = Gravity.TOP | Gravity.CENTER;
            params.x = ((getApplicationContext().getResources().getDisplayMetrics().widthPixels) / 2);
            params.y = ((getApplicationContext().getResources().getDisplayMetrics().heightPixels) / 2);
            windowManager.addView(imageView, params);
        }
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        * stopped, so return sticky.
        */
        return START_STICKY;
    }

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

        if (imageView != null) {
            try {
                windowManager.removeView(imageView);
            } catch (Exception e) {

            }
        }
        /**** added to fix the bug of view not attached to window manager ****/

您是否通过调用以下intent来请求运行时权限?

private void requestOverlayPermission() {
    if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.M) {
        return;
    }

    Intent myIntent = new Intent(Settings.ACTION_MANAGE_OVERLAY_PERMISSION);
    myIntent.setData(Uri.parse("package:" + getPackageName()));
    startActivityForResult(myIntent, APP_PERMISSIONS);
}

然后在onActivityResult()中检查Settings.canDrawOverlays(this)是否为true,否则通过调用above方法再次请求权限。

Source SYSTEM_ALERT_WINDOW字符串SYSTEM_ALERT_WINDOW允许应用使用类型TYPE_APPLICATION_OVERLAY创建窗口,显示在所有其他应用之上。很少有应用程序应该使用此权限;这些窗口用于与用户进行系统级交互。

注意:如果应用面向API级别23或更高级别,则应用用户必须通过权限管理屏幕向应用明确授予此权限。该应用程序通过发送动作ACTION_MANAGE_OVERLAY_PERMISSION来请求用户的批准。该应用可以通过调用Settings.canDrawOverlays()来检查它是否具有此授权。

尝试将WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY改为WindowManager.LayoutParams.TYPE_PHONE
