Keep your android setting as it is when you use for shipping build, and make test build.
This command below is I used in my environment.
E:\UnrealEngine\Engine\Build\BatchFiles\RunUAT BuildCookRun -nocompileeditor -nop4 -project=E:/Development//.uproject -cook -stage -archive -archivedirectory=E:/Build -package -clientconfig=Test -ue4exe=UE4Editor-Cmd.exe -pak -prereqs -distribution -nodebuginfo -targetplatform=Android -cookflavor=ETC1 -build -utf8output -compile
and install on your device, you can get the log by ‘adb logcat -s UE4’.
You don’t need to download everytime from market.
