In my android device (Sony Xperia J ), when i try to open Google Play, it is unable to open.
i use wifi always....
is there any trouble shooting with that
perhaps there is old version of google play on your Sony Xperia J , this can cause problems, you should update.
It, or your login, may have become corrupted. Go into Settings, then Manage Apps. Find and select Play Store. Clear Cache and see if it helps. If not, go back and delete Data. Try again. If it still does not work, go into Settings, then Accounts and select Google. Select your account and remove your account (or accounts). Try the Play Store again (you will have to login again). If it still does not work, go back into Manage Apps and uninstall the updates for Play Store. Try to open the Play Store and update it if you can access it again. Let us know if you still have trouble.
