Android IllegalStateException while finishing Activity [closed]

Question

I got this exception

"java.lang.IllegalStateException: Can not be called to deliver a result" 

And didn't immediately understand why. Below is my answer to why this happened, maybe this helps someone.

Well, this has helped me and it looks as if it has helped other as well. So maybe not so off-topic right? – Yecies

Answer 1

I had called finishAffinity() after having set a result code. Android was complaining that it will never be able to deliver the result when calling finishAffinity().

Solution: either don't set the result before calling finishAffinity(), or set the result again before calling finishAffinity() but this time with Activity.RESULT_CANCELED as the result code:

setResult(Activity.RESULT_CANCELED);
finishAffinity();

Not sure if the API changed, but I believe this is supposed to call setResultCode() instead of setResult(). – Anatol

I'm still seeing setResult() in the docs...? developer.android.com/reference/android/app/… – Puling

@DaveLeeds there is no "setResultCode()" for Activities, only BroadcastReceivers – Ethelynethene
