i'm trying below code, but getPackageName() method didn't return aar packagename

Signature[] sigs = context.getPackageManager().getPackageInfo(context.getPackageName(), PackageManager.GET_SIGNATURES).signatures;
for (Signature sig : sigs){

}

Answer 1

The AAR library is only read during compilation time. When you build an App that uses that library the AAR is "included" and merged with the App code, so the PackageName in runtime is the one of the App and not the one of your library. Signin an AAR file is used to make developers sure about the source of that file, and nothing else. In runtime that signature is lost after the build procedure.

You can simply get the package name by accessing a class from the .aar library. Suppose you have a class in the library named Sample.java , then you can get the package name like this:

String packageName = Sample.class.getPackage().getName();
