I have 3 classes in my example:
Class A, the main activity. Class A calls a startActivityForResult:
Intent intent = new Intent(this, ClassB.class);
startActivityForResult(intent, "STRING");
Class B, this class is a TabActivity:
Intent intent = new Intent(this, ClassC.class);
tabHost.addTab...
Class C, this class is a regular Activity:
Intent intent = this.getIntent();
intent.putExtra("SOMETHING", "EXTRAS");
this.setResult(RESULT_OK, intent);
finish();
onActivityResult is called in Class A, but the resultCode is RESULT_CANCELED
instead of RESULT_OK
and the returned intent is null. How do I return something from the Activity inside a TabHost?
I realize that the problem is that my Class C is actually running inside of Class B, and Class B is what is returning the RESULT_CANCELED
back to Class A. I just don't know a work around yet.

Oh, god! After spending several hours and downloading the Android sources, I have finally come to a solution.
If you look at the Activity class, you will see, that
finish()
method only sends back the result if there is amParent
property set tonull
. Otherwise the result is lost.So my solution is to set result to the parent activity if present, like that:
I hope that will be helpful if someone looks for this problem workaround again.
