Why signed android apk is not running on emulator

Question

I have made a signed apk of an android project. Whenever my client try to run it on the emulator, he faces the following error message:

D:\\Android\\android-sdk-         


        

Answer 1

You can run the Command:

C:\Program Files\Android\android-sdk\platform-tools>adb logcat

It will give you a more detail on which exact file is not signed:

Package has no certificates at entry assets/META-INF/AIR/application.xml; ignoring!
