    How to make app continue running after turning off phone screen?

    edited October 2019 in General questions
    Hi guys!

    I need app to continue playing when user turns screen off.
    Can we do it somehow in Gideros?

    (Currently when user turns screen off, Event.APPLICATION_SUSPEND triggers
    and Event.APPLICATION_RESUME after turning screen on)

    Can we ignore that Event.APPLICATION_SUSPEND and make app run there normally like nothing happened?

    Many thanks!

      Basically you can’t. What you are trying to do is called background activity, and phones typically forbid that, except for very specific use cases.

      я так робив з APPLICATION_SUSPEND це працює -просто зберігаєш гру при вимкненні а потім при увімкненні вираховуєш час і зміни за цей час у грі, також є інший варіант використати Application:setKeepAwake -і самому затемняти екран імітуючи виключення дисплею..

      thx guys, got it, I guess for such purposes I would have to learn freaking Android Studio
      (but I guess I'll skip learning freaking Android Studio for now, I already have enough adventures in my life)

      @Apollo14 I'll try to have a look at this in android studio when I have time and will come back!

      Hey guys! @hgy29 @MoKaLux
      I've found description of my intentions: https://stackoverflow.com/questions/39080815/continue-playing-the-music-when-screen-goes-off
      (actually I need just mp3 to continue playing)

      People on stackoverflow say that event ".onPause" triggers.
      Does Gideros also react to that ".onPause" event? Can it be ignored somehow?

      p.s. I'm looking at audio-related files https://github.com/gideros/gideros/blob/master/libgid/src/gaudio.cpp
      and https://github.com/gideros/gideros/blob/master/libgid/src/android/gaudio-background-mediaplayer.cpp
      but still have no idea what could possibly be done

      Many thanks!

      @Apollo14 short answer is: not possible right now.
      Long answer: from the github source code it seems that the sound (music) is paused when your app is paused (screen off, put in background, ...)
      It seems to be this code for android:
      https://github.com/gideros/gideros/blob/master/android/GiderosAndroidPlayer/app/src/main/java/com/giderosmobile/android/player/GGMediaPlayerManager.java
      public synchronized void onPause()	{
	if (suspended_)
		return;
	for (int i = 0; i < channels_.size(); ++i)
	{
		Channel channel = channels_.valueAt(i);
 
		if (channel.player == null)
			continue;
 
		if (channel.player.isPlaying())
		{
			channel.player.pause();
			channel.suspended = true;
		}
	}	
	suspended_ = true;
}
      This code is called in the GiderosApplication.java file.
      Unfortunately you cannot modify this file yourself because it is precompiled inside gideros.aar file in the template (see: http://forum.giderosmobile.com/discussion/7802/media-plugin)

      PS: I am watching the video to see the best way to use media in android (from your so question you posted above). done!
      PS2: there seems to be much more to this (putting controls on the home screen, ...) https://github.com/android/uamp

      Wow THX! That's really helpful!
      So after commenting out this piece of code in GGMediaPlayerManager.java and recompiling gideros.aar, audio will continue playing after screen is turned off?
      public synchronized void onPause()	{
	if (suspended_)
		return;
	for (int i = 0; i < channels_.size(); ++i)
	{
		Channel channel = channels_.valueAt(i);
 
		if (channel.player == null)
			continue;
 
		--if (channel.player.isPlaying())
		--{
		--	channel.player.pause();
		--	channel.suspended = true;
		--}
	}
	suspended_ = true;
}
 
public synchronized void onResume()
	{
		if (!suspended_)
			return;		
 
		for (int i = 0; i < channels_.size(); ++i)
		{
			Channel channel = channels_.valueAt(i);
 
			if (channel.player == null)
				continue;
 
			--if (channel.suspended)
			--{
			--	channel.player.start();
			--	channel.suspended = false;
			--}
		}	
 
		suspended_ = false;
	}
      If so, I can temporarily replace my original gideros.aar with custom gideros.aar and build my android app? (then switch back to original file for other projects)

      How to recompile gideros.aar? In can be done in QT?
      @hgy29 would you be so kind to recompile this file? (if it's all set on your machine, I've never worked with QT, not sure how it's all done there)
      MANY THANKS guys!

      You don't need QT, just android studio for that part, but anyway I can do it for you to try

      Hey guys!! I've just managed to compile couple of apks with and without modified 'gideros.aar' file.
      It works like a charm now! Audio is playing when screen is off.
      @MoKaLux @hgy29 Thanks a lot guys!!

      This is interesting. I gather this change effects only the sound player. Is there any way other processes like Timer events could continue after the screen turns off due to inactivity?

      Basically no, phones usually stop running your app when they are in background. There are only a few exceptions (background location, Bluetooth) and they are platform dépendant.
