Window type error

Window type error - android

I'm creating a audio swipe card reader but I'm getting an error with windows. I can't trace what causing the error in my codes. Can anyone hel me to point what causing the error in my codes? any thought will be highly appreciated.
Here is my codes:

Problem seems to be in onAttachedToWindow(). Change the function as below and give it a try.
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}

your targetSdk must be less than 14.
try setting it to 13
Check this Answer. And it works for me.

my app is in play store under name(domino calculator) here

you are using MediaPlayer objPlayer,objPlayer2 and you have start like
this objPlayer2.start(); but when you are minimize the app onPause() method
called and you have to stop your mediaplayer like this.
#Override
public void onPause(){
super.onPause(); //Always call the superclass method first
objPlayer.pause();
objPlayer2.pause();
PowerManager pm = (PowerManager)

When I remove a window from service class then i am facing these errors and window taking too much time to show

I need show a dailog when a outgoing call is detect and remove it when call is disconnect.
Please let me know the error and how can I resolve it.
Following is my code:

Try to tag the data model/ data source with your list view view.setTag(dataModel) in getView method of your adapter class.

Why not try RecyclerView instead of ListView and use Fresco Image Library?

Activity Memory Leak reported by LeakCanary - WindowManagerGlobal

Window type error - android

Problem seems to be in onAttachedToWindow(). Change the function as below and give it a try. public void onAttachedToWindow() { this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); super.onAttachedToWindow(); }

your targetSdk must be less than 14. try setting it to 13 Check this Answer. And it works for me.
