    I am getting this error whenever I try running my app. The app crashes when I press the sign up button. I am using android studio version 3.6.3 and my platform is windows 10. Here is the error screen:

    Why you need to initialize your xml twice?

    Since you already have setContentView(R.layout.activity_register);, so just remove this line:

    Code (Java):
    1.  View mView = getLayoutInflater().inflate(R.layout.activity_register, null);
