I have this strange problem in my App. My app has a GSigninActivity which is shown after Splash screen to facilitate Single Sign On with Google and Firebase. The problem is that on First Install and Launch, the app directly goes MainActivity without asking for Sign In.I have to the log Out from there and then Sign In. How is it that some Sign in data is present. Please Help.

Looks like you have android:allowBackup="true" in your AndroidManifest.xml.
Since Android 6.0 (API 23), Android has offered the Auto Backup for Apps feature as a way for developers to quickly add backup functionality to their apps. Auto Backup preserves app data by uploading it to the user's Google Drive account, where it is protected by the user's Google account credentials. The amount of data is limited to 25MB per user of your app and there is no charge for storing backup data.
You may want to disable backups. Read here in detail https://developer.android.com/guide/topics/data/autobackup.html#Files
