[Interest] Qt App crashing on first install after beinged installed from Google Play store but working perfectly when launched locally.

[Nuno Santos]

Hi,

I’m facing one of those problems that can lead someone to madness very quickly.

Yesterday I have updated one of my apps to Qt 5.10 and uploaded it to Google Play store. I’m using Proguard to obfuscate it.

It happens that when testing the release build locally it works without any problem.

However, when installed from the Google Play store, it crashes the first time. If I try again, it works without problems, but on the first launch after install it always crashes.

I have sent the reports to Google Play but the available information is not very useful:

java.lang.RuntimeException: 
  at android.app.ActivityThread.handleReceiver (ActivityThread.java:3021)
  at android.app.ActivityThread.-wrap18 (ActivityThread.java)
  at android.app.ActivityThread$H.handleMessage (ActivityThread.java:1561)
  at android.os.Handler.dispatchMessage (Handler.java:102)

  at com.android.internal.os.ZygoteInit.main (ZygoteInit.java:776)

Caused by: java.lang.ClassNotFoundException: 
  at dalvik.system.BaseDexClassLoader.findClass (BaseDexClassLoader.java:56)
  at java.lang.ClassLoader.loadClass (ClassLoader.java:380)
  at java.lang.ClassLoader.loadClass (ClassLoader.java:312)
  at android.app.ActivityThread.handleReceiver (ActivityThread.java:3016)

It seems it is not being able to find some class…. but which one!?

I have added the Proguard mapping files to the Google Play console but so far I haven’t seen any report deobfuscated…. I don’t know how much time it takes to make it available.

Maybe some of you have already passed through this nightmare before. 

Any ideas?

Thanks!

Regards,

Nuno
