Market Application (process com.android.vending) has stopped unexpectedly I have an HTC Android running 2.2. The market application was running perfectly before I  updated it.

It was when the Google changed Market application "Android Market" to "Google Play".
As soon as I pressed the "accept and download updates" button it started getting "process com.android.vending has stopped unexpectedly".

I research a little bit about this problem, I get the answers like 


I have to reboot my phone.
I have to uninstall updates.
I have to uninstall the market application and reinstall it.


I want to know how I can fix this problem.
Clearing the cache worked for me. settings / applications / manage applications / google play store and then clear data.
