I am using Firestore in my app and in debug version, everything works as expected. However, when using release version, I get this error:

        maven { url 'https://jitpack.io' }
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

According to https://developers.google.com/android/guides/client-auth I've added SHA-1 of release version, but app still crashes on launch. Any help?

As @Doug Stevenson said in comment, there was a problem with Minification. What i did is:

Change

        shrinkResources true
        minifyEnabled true

To

        shrinkResources false
        minifyEnabled false
