Player.Stop bug with android 5.0 lollipop

[Richard Incorvia]

Hello,

I don't know where to post a bug report so I'm posting it here. If there is a better place let me know and I'll post it there too.

Summary: On android 5.0.1 lollipop starting and stopping the Player more than once results in a Run Time Error and crashes the app. This only happens using android 5.0. The bug is not present in android 4.4 kitkat.

Bug Reproduction: I have created a test app with only two buttons (player.start and player.stop). Player is set to play an mp3 and is on loop. Player.start begins playing the mp3 on loop. Then the player.stop will stop the sound. When you repeat this for the second time, pressing the player.stop button will cause a run time error every time. This only happens running android 5.0. I've tested this on android 4.4 and it doesn't cause the app to crash. Here are the devices I've tested this with:

Nexus 6 Lollipop: Crash

Nexus 5 Lollipop: Crash

Moto X Lollipop: Crash

Moto X Kitkat: Fine

Galaxy Nexus Kitkat: Fine

Galaxy S3 Kitkat: Fine

Work around: Using Player.Pause does not cause the run time error. This is limited in its usefulness though.

I forgot to include the simple app I made to test this.

thank you for the report. 

could you add your small test project (aia file) into this thread to demonstrate that issue?

Here you go.

I can confirm this issue on Nexus 5 running Android 5.0.1: after pressing Start - Stop - Start - Stop in the Blocks Editor the following window appears:

this is from logcat (see also attachment)

@MIT: please check!

Thanks for reporting this and especially for clear description and aia file and log excerpt.   It looks like it might be related to this issue

I am getting the same error using my Nexus 7 tablets running 5.0.2. Player1.pause works fine.

Player.stop
Player.start

Chrash on Motor G with Lollipop here too.
Any news on this ?

I re-tested this on 5.1.1 and it works. 
I'll close the issue.  People still running 5.0.1 would want to upgrade anyway, for other reasons.
