I double checked this latest expansion file bug. I uploaded the same project but deleted some files to get the APK size small enough that expansion files are not needed. The music was there. So it must be expansion file. I’ll try with ogg… If it really is the file format.
As I see this, Corona has two problems with expansion files:
-
The original problem (the app runs in background when the permission alert is waiting to be answered -> crash). This problem can be handled with some code, but of course it’s just a fix…
-
Apparently mp3 files don’t work when using Expansion Files. This is a major bug.
What I can do? Our Android launch is delayed because of this. Is it possible that Corona staff could take a look at this? If you think this is a minor problem and it takes time to solve this, please let us know.
EDIT: Made new tests:
-
Expansion Files & mp3 files seems to work - at least somehow. We have a module for playing background music (works iOS, APK, Google Play APK, but now when using Expansion Files).
-
Same version but I tried ogg format instead of mp3 format, and it works also when using Expansion Files.
This is quite a mess to be honest. The point is that the APK version installed to a device and Google Play version without expansion files work the same way but expansion file version doesn’t. What else we may find? And it’s really slow to test the expansion file version, 'cause you have to upload it to Google Play everytime.
EDIT: More tests (I’m testing for you and hopefully this helps the dev)
- It seems that it’s not the file format. It seems that if the extension file is new, all works ok. That’s why I got the ogg files working, 'cause when I added some ogg files, I have to upload new extension file. I’ve tested this now twice at this seems to be the case. So if my app version is 20, but the the extension file hasn’t changed and I have to use the extension file from the 18 version, music is not playing.
