Is this an application you're developing? You don't give us a whole lot of detail about what the error is so we can't very well tell you, if this is an application you're developing.
If this is an app you've installed and you're getting an error, I suggest you contact the developer but you'll need to give them a LOT more info than you gave us. What device? What OS version? What security patch level? What was the exact error? Not responding to them (or us) will get you nowhere in finding a resolution.
