Tip
Ubuntu Linux 32 bit developers who encounter problems (as I did) in running adb (debugger) when debugging an Android app should read here for solution ...
http://askubuntu.com/questions/714653/adb-android-studio-ubuntu-error-unable-to-detect-adb-version-adb-output-hom
This applies to Ubuntu Studio and Qt Creator.
I guess one day I'll have to move from 32 to 64 bits .. but not right now.
