If clearing the cache and data in your Google Play Store didn’t work then you may need to go into your Google Play Services and clear the data and cache there. Doing this is easy. You need to go into your Settings and hit Application manager or Apps. From there, find the Google Play Services app (the puzzle piece).
Can not download from Google Play?
If you still can’t download after you clear the cache & data of the Play Store, restart your device. Press and hold the Power button until the menu pops up. Tap Power off or Restart if that is an option. If needed, press and hold the Power button until your device turns on again.
