NoSuchMethodError in lxg.a - nosuchmethoderror

Question

My users are getting this crash from my app, but I haven't a clue where it is coming from. It is mostly coming from Gingerbread users. The bug report from the Developer Console looks like this:
java.lang.NoSuchMethodError: android.view.ViewParent.requestSendAccessibilityEvent
at lxg.a(Unknown Source)
at lxx.a(Unknown Source)
at kzf.c(Unknown Source)

The app is here:

The app uses in app purchases and the camera. Could it be coming from one of those packages?

Answer 1

android.view.ViewParent.requestSendAccessibilityEvent was added in API 14 (Android 4.0). This crash appears when you try to call the method on a device with a lower API level.
The following code:
at lxg.a(Unknown Source)
at lxx.a(Unknown Source)
at kzf.c(Unknown Source)
Looks like an obfuscated code. So you're either using Proguard to obfuscate your code or you're using an external library which was obfuscated.
If you obfuscated the code with Proguard, then you can decode the obfuscated code as explained here. If you are using some external obfuscated library, then you can either search their documentation to see if they support API levels lower than 14. If they do, then you can send them a bug report.
