I'm making a login activity that has a Sign in with Google Button
I am using a Firebase Auth to provide a Google sign-in method. I am following this documentation from firebase. I already follow along with the documentation, but my apps keep stoping. Why this problem occured? I've watched so many tutorials and searched for the same problem in Google. But I can't solve this problem. Here is my LoginActivity and the activity_login.xml code.
Edit
After sawing the logcat, the Google Mobile Ads SDK was initialized incorrectly. Here's the logcat
******************************************************************************
