necessarily complete, but they are common and typical. Then, how can we check whether the "signature is successful" after the release ??? In fact, the APK file installed from the development environment to the mobile phone using the eclipse + ADT plug-in already contains the debug signature file of the ADT plug-in.

Everything works normally when using a simulator; When using a real machine, {"data": NULL, "errcode":-103, "MSG": "check sign error", "RET": 3} returned values always appear.
