Failure [INSTALL_FAILED_INVALID_APK]

Question

When I click to run a project I just created in Android Studio 0.2.10 and select my Android (connected by USB with debug by USB on) I get this error:

Waiting         


        

Answer 1

i got similar issue once, what i observed was, package name in my Androidmanifest.xml was started with one empty space character. like " com.example.test" instead of "com.example.test"

I removed all such invalid spaces from my manifest file, it solved my problem

Edit 1: '-' in package name also cause same issue on some android versions
