Answer 1

You are probably using or accessing something which is simply supported in higher android SDK, as the error shows here java.lang.Class.newInstanceImpl(Native Method) . I happened to have the same kind of VerifyError while I was using String.isEmplty(); . It seems you have same kind of problem as the message showing error in java.lang.Class

Thrown when the "verifier" detects that a class file, though well formed, contains some sort of internal inconsistency or security problem.

Here is official docs

Answer 2

Possible causes:

1. You might have imported something which is using different support v4/v7 library version.

2. You are targeting something from a higher SDK version. In that case, update your support repository and SDK build version.

Answer 3

Thanks everyone for your support and answers, may be your answers are right but in my case I used extra variables in one method while I was testing, so this exception appeared. Now I get rid of redundant things in my code and it start working. It may help others.
