How to run (not only install) an android application using .apk file?

Question

Is there any command on cmd.exe that would allow me to start the main activity of a particular android application using the .apk file of that appl

Answer 1

I put this in my makefile, right the next line after adb install ...

adb shell monkey -p `cat .identifier` -c android.intent.category.LAUNCHER 1

For this to work there must be a .identifier file with the app's bundle identifier in it, like com.company.ourfirstapp

No need to hunt activity name.
