Just found the error...
I was writing/reading a file from File.DirInternal was ther setup for running specific app from my launcher!!! changing that to DirRootExternal saved MY DAY!
SORRY ! and thank you all guys again.
at app i want to load it there is a 2nd activity not MAIN is it possible without trick to say at intent run specific activity (ROCKING)....
Dim pm As PackageManager
Intent1 = pm.GetApplicationIntent("mvt.client/ROCKING")
ofcourse not works.. is there a solution.. ?
A solution thought was writing to external root a file with the name of activity or a text reminds what activity i want...
and then at MAIN / activity_resume read that file and startactivity the ROCKING...
But is there another way at Intent ?
