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 a mParent
property set to null
. Otherwise the result is lost.
public void finish() {
if (mParent == null) {
int resultCode;
Intent resultData;
synchronized (this) {
resultCode = mResultCode;
resultData = mResultData;
}
if (Config.LOGV) Log.v(TAG, "Finishing self: token=" + mToken);
try {
if (ActivityManagerNative.getDefault()
.finishActivity(mToken, resultCode, resultData)) {
mFinished = true;
}
} catch (RemoteException e) {
// Empty
}
} else {
mParent.finishFromChild(this);
}
}
So my solution is to set result to the parent activity if present, like that:
Intent data = new Intent();
[...]
if (getParent() == null) {
setResult(Activity.RESULT_OK, data);
} else {
getParent().setResult(Activity.RESULT_OK, data);
}
finish();
I hope that will be helpful if someone looks for this problem workaround again.
