Bug when getting string resource

[janheinrichmerker]

Seems to be a framework bug but anyway I wanted to let you know:

Bug was reported on a OnePlus ONEPLUS A3003 running Android 7.1.1.

I see you modified ISCLicense to include a onViewCreated method. This is likely a bug in your code, as all license objects as singletons and kept in a static map. You probably have a context leak somewhere and using a destroyed context.

[janheinrichmerker]

I didn't modify anything. Using library version 1.8.1. Maybe the specific user had something like Xposed on his phone that modified the code?

[hameno]

Hmm, that whole stacktrace looks weird, those linenumbers and method names do not match with that version. Are you sure, that you used the correct mapping file?

[janheinrichmerker]

You're right, that might actually be the problem
