I don’t know if this is for everyone, but updating Eclipse and cleaning my project resulted in a problem with IMarketBillingService where
@Override public android.os.IBinder asBinder()
It was asking for me to remove the @Override as well as in several other places. Just to help anyone who has the same problem I’m including the answer because the current answers didn’t work for me.
Right click on your project
Click properties
Click “Java Compiler” on the left
Uncheck “Enable project specific settings”
Click “Configure Workspace Settings”
Set the JDK Compliance -> Compiler compliance level to 1.6
Click apply and clean your project.
Should now work.
If it doesn’t set more values to 1.6 until it does work.
