Android Google Place Picker working in Signed APK but not working in Live app

After several days of investing time for finding solution of this problem. Finally I got the solution. It is because of Google Play App Signing .

With Google Play App Signing: You sign your app with your upload key. Then, Google verifies and removes the upload key signature. Finally, Google re-signs the app with the original app signing key you provided and delivers your app to the user.

So, when I Created API key for "Google Places API for Android" I have restricted that key using my package name and my SHA-1 of Signed APK's KeyStore.

Now that is under "Upload Certificate" and it is not used, as I have to pass my App Singing Certificate's SHA-1 to Google Developer Console. And after doing that my Google PlayStore's live app's Google PlacePicker working well.
