More bug fixes.
Since version R248 I can't export an APK that works, nor can I publish an app created by Construct 3 on Google Play, it doesn't work! Bug reports are closed at the speed of light, construct 3 is never to blame.
A number of problems really aren't caused by Construct, in which case we really can't help. FWIW I just tried a test APK build in r250 and it seemed to work fine. I also don't see any significant changes that were made to Android in r248 so it may well be unrelated to any issue you were having.
