As of Android Studio 2.2, SHA-1 fingerprint can be obtained from inside the IDE itself. The most common way developers use to find the fingerprint is shooting up the console/terminal/cmd prompt and using the keytool command. Here’s an example for that:
keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android
This way of finding the SHA-1 is pretty old now, as a developer you always want things like these to be on on fingertips. Now I will show you a better and faster way to get SHA-1 fingerprint.
Step 1. Open your project in Android Studio.
Step 2. Click on Gradle Menu on the right side and expand it.
Step 3. Click on android and then signing report.
