Question

I have 2 Activities, A and B.

A invokes B with an intent and request code –

startActivityForResult(i,123);

… later I want A to stop B and then itself, so in A I did

finishActivity(123);
finish();  // finish itself

… but B doesn’t stop! BUT if I set breakpoints at all the onStop’s and onDestroy’s and step through in the debugger everything works perfectly and both Activities go away. (this suggests a timing or race condition)

However if I comment-out A’s finish() …

finishActivity(123);
// finish();  // finish itself

B does finish but A doesn’t because its finish has been taken away. What is the correct way to have one activity finish another one that it created, and then finish itself?

Thanks in advance.

Answer 1

See if this works:

finishActivity(123);
runOnUiThread(new Runnable() {
    public void run() {
        finish();
    }
});

The reason I suggest this is that I think the call to finish() is not giving finishActivity(123) a chance to do its thing. By calling runOnUiThread, the call to finish() will take place on the next loop through the UI message queue.
