Throws Securityexception When Signing With The Default Debug Keystore

I am receiving a SecurityException since yesterday when I launch the service using signature protection level for permission with the default debug keystore. The strange thing is I

Solution 1:

As I make my service unreachable by setting my signature as a permission requirement, I got this error randomly when using the debug signature. I don't know the reason. But I delete the permission setting of my service while developing when I got this error and insert it again before signing the application. But, as I said, generally I don't get this error.

I know that this is not the actual answer. But, it is a work around. Hope it helps someone else.

Thanks.
