#Override
public void onPlayerError(ExoPlaybackException error) {
}
#Override
public void onPositionDiscontinuity() {
}
});

how to disable back-button on rewarded video show/playing?

During the Rewarded video play i want to disable the back button and set a minimum waiting time . is it possible to do?On which function should i change to complete my desired functionality?
here is my code
if (mAd.isLoaded()) {
mAd.show();
} else {
startActivity(new Intent(EssayActivityQstnShow2.this, Essay_Answer_Show.class));
}
and here is Rewarded video ads handling methods
private void loadRewardedVideoAds() {
if (!mAd.isLoaded()) {
mAd.loadAd(getResources().getString(R.string.rewardedvideoid), new AdRequest.Builder().build());
}
}
#Override
public void onRewardedVideoAdLoaded() {
}
#Override
public void onRewardedVideoAdOpened() {
// onBackPressed();
}
#Override
public void onRewardedVideoStarted() {
// onBackPressed();
}
#Override
public void onRewardedVideoAdClosed() {
startActivity(new Intent(EssayActivityQstnShow2.this, Essay_Answer_Show.class));
}
#Override
public void onRewarded(RewardItem rewardItem) {
}
#Override
public void onRewardedVideoAdLeftApplication() {
}
#Override
public void onRewardedVideoAdFailedToLoad(int i) {
loadRewardedVideoAds();
}
#Override
public void onRewardedVideoCompleted() {
startActivity(new Intent(EssayActivityQstnShow2.this, Essay_Answer_Show.class));
}

Try below code
private boolean isVideoPlaying;
#Override
public void onRewardedVideoStarted() {
isVideoPlaying = true;
}
#Override
public void onRewardedVideoAdClosed() {
isVideoPlaying = false;
}
and than onBackPress() check, if the video is playing or not
#Override
public void onBackPressed() {
if (!isVideoPlaying)
super.onBackPressed();
}
Before implementing this, please read the policies carefully.

You must override the onBackPressed callback in activity and remove line super.onBackPressed(). then if the user taps the back button the activity will not close.
If you have no access to the Essay_Answer_Show activity check can you create another activity which extends that or clone library and tries to modify activity?

Youtube API: listener onVideoEnded() not working

i'm trying to use the onVideoEnded() method, but by any reason it is not working.
I've implemented PlayerStateChangeListener but it did not seems to be working. I've added toasts on every method of the implementation, they are not firing.
when this activity starts, it automatically plays the video:
#Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player,
boolean wasRestored) {
if (!wasRestored) {
player.loadVideo(videoId);
}
}
And this is the interface implementation:
//start interface implementation
#Override
public void onLoading() {
android.widget.Toast.makeText(getApplicationContext(), "onloading",
android.widget.Toast.LENGTH_LONG).show();
}
#Override
public void onLoaded(String s) {
android.widget.Toast.makeText(getApplicationContext(), "onloaded",
android.widget.Toast.LENGTH_LONG).show();
}
#Override
public void onAdStarted() {
android.widget.Toast.makeText(getApplicationContext(), "onadstarted",
android.widget.Toast.LENGTH_LONG).show();
}
#Override
public void onVideoStarted() {
android.widget.Toast.makeText(getApplicationContext(), "onvideostarted",
android.widget.Toast.LENGTH_LONG).show();
}
#Override
public void onVideoEnded() {
android.widget.Toast.makeText(getApplicationContext(), "onvideoended",
android.widget.Toast.LENGTH_LONG).show();
}
#Override
public void onError(YouTubePlayer.ErrorReason errorReason) {
android.widget.Toast.makeText(getApplicationContext(), "onerror",
android.widget.Toast.LENGTH_LONG).show();
}
Am i missing something?
thanks!

I just figured it out and i'll post it in case somebody have the same issue. You just need to add a new class with the state listener just as it is described on
this website

Play Youtube video in background using YouTubePlayerSupportFragment

I have been successfully using YouTubePlayerSupportFragment to play YouTube videos.
But I still need to continue playing in the background, when the back button is pressed.
If you have any ideas, please share with me. Thanks!
Here is my code -
YoutubePlayerFragment class
public class YoutubePlayerFragment {
public static String DEVELOPER_KEY = "DEVELOPER_KEY";
public static boolean isFullScreen;

}
#Override
public void onInitializationSuccess(Provider arg0, YouTubePlayer player,
boolean paramBoolean) {
PlayerService.youTubePlayer = player;
PlayerService.youTubePlayer.setPlayerStyle(YouTubePlayer.PlayerStyle.DEFAULT);
setListener(fragment.getActivity());
}
});
replaceFragment(fragment);
}
public static void replaceFragment(final Fragment fragment) {
if (fragment == null)
return;
FragmentManager fragmentManager = fragment.getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.youtubeplayerFrameLayout,
MainFragment.youtubePlayerFragment);
fragmentTransaction.commit();
}
public static void setListener(final Activity activity) {
PlayerService.youTubePlayer.setOnFullscreenListener(new OnFullscreenListener() {
