Can I do this with Tasker?
Yup
Maybe with "code" action - shell?
Yup
I not really familiar with scripting and coding
Nor am I..
You can use the ; to chain shell commands together, so I would try something like this in the shell action.
am start -a android.intent.action.MAIN -n com.vmlite.vncserver/.MainActivity;/data/data/com.vmlite.vncserver/files/vmlitevncserver
Or this..
am start -a android.intent.action.MAIN -n com.vmlite.vncserver/.MainActivity /data/data/com.vmlite.vncserver/files/vmlitevncserver
