In the last days I got some questions about how to resign the apk file you want to test. And here is the answer. First some basic about the signatures in Android development! A signature is needed to identify the author of the Android application. A signature mostly contains information like:
- First name
- Last name
- Name of the organization
- City
- State
- Country Code
For more information please have a look at the Android SDK developer guide http://developer.android.com/guide/publishing/app-signing.html
