Application restart suddenly

I made simple picture matching game with four Activities After finishing you can play again.
The problem is most of the time the game stops and return to previous
The error:

Your exceptions shows that you are calling activity that is destroyed or vice versa.
Make sure there is no activity or dialog that is called after destroying that activity.
For more information Check following link
Bad window token, you cannot show a dialog before an Activity is created or after it's hidden

you are trying to show the dialog for a context that no longer exists.
try using this in side your onFinish() method of startTimer()
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity().this);
Also check if activity is visible, like, e.g.
if (getActivity().hasWindowFocus()) {
// create & show dialog here
}

In Exoplayer,How to reload and resume playback automatically?

I"m streaming HLS video with EXOPlayer and it is working perfectly. However, If there is some changes with HLS streaming source video and then video playing stopped and keep showing loading circle.

Stop repetitive radio streaming android

I have a problem with my app. I have an app that streams radio stations. The stream starts when the user clicks on a item of the gridview. To stop the stream i made a button(stop) that appears when the stream starts. The problem appears when the user click many times the same item of the gridview because when click on stop button the stream don't stop, how can i solve that ?

No one knows how to do that ?

it is better to not start playing if the selected gridview item is already playing. so you can store the value of playing gridview item and check it before you call mRadioManager.play("http://s6.mediastreaming.it:9064/", mediaPlayerCallback);
