回答1:
There are a couple of clarifications needed to answer your question
Was the app working fine before you migrated to androidx?
Does the app work without crashing on other devices but crashes on just android 10.0?
did you refactor your package names correctly? If your file names in the manifest or generated code have a package name starting with capital letters, 'class not found exception' could result
You can try pasting (if possible) the Github link to the whole project for proper debugging.
However, from the code you pasted, your minsdkversion= 16 in your project build.gradle ext block differs from the minsdkversion= 15 in your app build.gradle file. The targetsdkversion also differs in the two files
回答2:
thanks for all the support i solved the issues, this was due to the usage of deprecated method, this was not related to migration
@Override
public Resources getResources() {
return new CustomResources(sharedPrefence, getAssets(), super.getResources().getDisplayMetrics(), super.getResources().getConfiguration());
}
custom Resources class cannot be used in this way in androidX, by removing this method from Baseactivity.java solved the problem, thanks for all your suppor
