I have two apps. From the first app main activity it calls startActivityForResult() for launching second app's main activity. I know I can send result through Intent from second app's main activity.
But for some case if second app's main activity launches another activity and it finish the main activity then how I can send result to first app's main activity from second app's another activity?
Let's assume that you have three activities - A
in the first app and B
and C
in the second app.
I see two possible scenarios:
A
starts for result B
starts for result C
. The result from C
is delivered to B
, B
delivers it as a result to A
. Intent
s directly - don't start B
for result, but use explicit Intent
s to return the result to A
. This means you should set A
's launch mode to singleTop
and use appropriate flags to make sure you won't end up with multiple instances of the activity. You can also fire Intent
s not directly to A
, but to a BroadcastReceiver
that will handle them accordingly.
