[cloud_firestore] Fixes crash on Android when run a transaction #87

hoc081098 · 2019-09-04T05:39:52Z

Description

Fixes crash on Android when run a transaction and without internet connection.
This occurred because:

Tasks.await(transactionTCSTask, timeout, TimeUnit.MILLISECONDS)
throws a Exception
→ result.error("Error performing transaction", e.getMessage(), null) will be called
→ transaction result is null
→ in addOnCompleteListener#onComplete:

    if (task.isSuccessful()) { // result is null
      result.success(task.getResult());
    }

will also be called
→ result#success has been called after result#error
→ This cause java.lang.IllegalStateException: Reply already submitted

Thanks for the PR! The cloud_firestore integration test crashed on this PR but fortunately the fix was easy. I've updated your PR with 928e052. (Yay tests!)

Nice work :)

creativecreatorormaybenot · 2019-09-07T21:20:16Z

Wow. Thanks so much for this PR. I was seeing this crash for quite a while now. In Crashlytics it shows as the following:

DartMessenger.java line 35

io.flutter.embedding.engine.dart.DartMessenger$Reply.reply

This PR resolves #102.
It was just now that I figured out why this was happening as well. Lucky that I saw this PR before finishing my implementation - saving me some work. This shows that it really is benificial to create an issue with a PR or include a stack trace or similar in the PR (or issue) description so that it becomes searchable. I searched for the crash, but could not find anything.

@collinjackson Is there a reason this is not being merged?

Guys, do you have any progress?!
I have used cloud_firestore: 0.12.9+4 and I get crash of my app due 'offline' transaction every time!
When it can be retested again? thanks.

I still get this crashing. Only on Android - LIVE devices and also simulators.

Basically occurs when I try and run a transaction when the device is offline

@fenchai23 Transactions are supposed to fail when offline; as it appears that your device was.
But I assumed it hard crashed? It's not supposed to do that :)
