I trying to create a view that is above other applications:
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);
I have looked in other responses and found the following things for "drawing over applications":
I am still getting "-- permission denied for window type 2038" error. As of now I am using TYPE_PHONE and it works, but it is deprecated and says to use TYPE_APPLICATION_OVERLAY. Can some one follow up on this as the TYPE_PHONE answer is not truly a resolution but a "patch work" solution that is deprecated in Android O.
I am running on Android 7.1.2
android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@1f47e89 -- permission denied for window type 2038 at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:3344) at android.app.ActivityThread.-wrap21(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1583) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6121) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:889) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:779) Caused by: android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@1f47e89 -- permission denied for window type 2038 at android.view.ViewRootImpl.setView(ViewRootImpl.java:703) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:342) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:93) at HeadService.TwoViewManager.(TwoViewManager.java:99) at HeadService.UIHeadService.onStartCommand(UIHeadService.java:65) at android.app.ActivityThread.handleServiceArgs(ActivityThread.java:3327) at android.app.ActivityThread.-wrap21(ActivityThread.java) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1583) at android.os.Handler.dispatchMessage(Handler.java:102) at android.os.Looper.loop(Looper.java:154) at android.app.ActivityThread.main(ActivityThread.java:6121) at java.lang.reflect.Method.invoke(Native Method) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:889) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:779)
I had the exactly same issue. I guess you should differentiate the target (before and after Oreo)
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" />
I had the exactly same issue in service class(before and after Marshmallow).
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,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
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) {
/* We want this service to continue running until it is explicitly
* stopped, so return sticky.
*/
return START_STICKY;
}
@Override
public void onDestroy() {
super.onDestroy();
if (imageView != null) {
try {
windowManager.removeView(imageView);
} catch (Exception e) {
e.printStackTrace();
}
}
/**** added to fix the bug of view not attached to window manager ****/
