I tried some methods posted on the website but nothing works. I tried clearing data and force-stopping the app, then reboot but after a while the app crashed when I tried downloading an application. I got this message: "The application Google Play Store (process com.android.vending) has stopped unexpectedly. Please try again"
I wiped also cache through the system reboot but I had the same problem but also sth strange happened, Google Play Books app re-appeared in my menu.
I tried also deleting hosts.txt from \system\etc folder and even editing it as suggested (There was only one line on my hosts.txt: 127.0.0.1 localhost):
but I had the same problem after a while.
I finally tried changing my Google account password and this helped only for a little bit as I got the same message. I get this message even when I am trying to download an app from the web version of Google play.
Can somebody help me please? Any ideas?
