Google Play Apps Editorial Board raises issue of sound playing after app was suspended (new Nexus 7)

You said earlier that you’re app is not receiving an “applicationSuspend” event, right?

If that’s the case, then that is the root cause of this issue, because Corona will automatically pause audio playback when it raises a suspend event.

If this is the issue, then we’re likely running into a multithreading issue.  Trouble is, we still can’t reproduce it… even after testing with your app.  So, if the problem is in fact in our code, we’re left guessing as to where it could be.  We’ll keep looking.

One more question.  Is your app using any plugins?

If you are, then we can double check them for multithreading issues.

Oh and one more question.  Are you positive that your app is built with build #1202 or higher?

Would you mind double checking please?

I ask because we thought we fixed this issue months ago.  Sometimes developers have a “build.settings” option or system setting set to force the Corona Simulator to build with a specific build number (or special beta version) and I want to make sure that hasn’t happened to you.  It’s rare, but sometimes it happens and causes confusion.

Just add the following line to your “main.lua” file.  It’ll print the Corona build number to the Android log.

   print("@@@ Corona Build: " … tostring(system.getInfo(“build”)))

Thanks.

Hi Joshua,

I thought that it is normal that we don’t get the “applicationSuspend” event before the shutdown when the power of the Android device is shut manually off using the button?

I get the event after the device is turned on again, closely followed by the resume event.

To your questions:

>Is your app using any plugins?

“Freeze!” is using the Google Play Games plugin for Leaderboards & Achievements, but e.g. the “Little Rainbow Fish” doesn’t use any plugins, and the same bug happens on the NEXUS 7.

>Are you positive that your app is built with build #1202 or higher?

Yes, in both cases I used 1206. This is definite, because I needed 1206 for the xxhdpi icons demanded by the Google Review Team, and now they accepted the apps and the xxhdpi icons are in.

Hm, both apps not only have the problem with the manual hard power off, but they both have the issue that the bg music sometimes continues to play when you do not touch the device for a while and a soft shutdown happens. In these cases the applicationSuspend event should have been sent, but it wasn’t. So this really seems to be the problem.

But you cannot test this with my apps, because for that part of the problem I made updates for my apps with the shutdown on idle set to false.

Best,

Andreas
