Android. Firebase: Keystore file does not exist: ~/.android/debug.keystore

Android Studio will do the SHA key generating part to save your time and effort. You've to find Gradle Project tab somewhere at the right edge of your Android studio. Open it up.

Under your project(root)>Tasks>android, find something called signingReport and run it by double clicking on it.

You will find your SHA1 and MD5 certificates in the Run section, below.

Copy the SHA1 and use it. Otherwise, debug signing certificate SHA-1 is optional in this case, so you can continue without this.


maybe you can try this, go to the right side of your android studio and then double click the signingReport

gradle
and you will find the SHA-1 here,
