To call an .apk file from another application

[vaishnavi_s]

I need to call an existing application using its .apk file from another application . There is no particular package for it as it was built using Flash professional. It doesnt have an activity also. Please sugest me a better way to do this.

This is what I have done

Intent intent = new Intent(Intent.ACTION_EXTERNAL_APPLICATIONS_AVAILABLE);
intent.setClassName("coroos.coro", "coroos.coro.ToBeCalled");

This is working well, as it has a package and "ToBeCalled" activity exists.

But my need is to call an application using its .apk file.
Please help me to do it.
Thanks in advance
