In Eclipse:
Window -> Preferences -> Android -> Lint Error Checking.
In the list find an entry with ID = ProtectedPermission. Set the Severity to something lower than Error. This way you can still compile the project using Eclipse.
In Android Studio:
File -> Settings -> Inspections
Under Android Lint, locate Using system app permission. Either uncheck the checkbox or choose a Severity lower than Error.
