[Android] Read "position" property of the async opened FileStream after writing data from Socket cause application crash

Here is the bugbase ticked: Bug#3982883 - [Android] Read "position" property of the async opened FileStream after writing data f...

Read "position" property of the async opened FileStream after writing data from Socket cause application crash.

It has been tested with AIR 14.0.0.178, AIR 16, AIR 17.0.0.144 and AIR 18.0.0.109 beta with Android 4.4.2 and Android 5.0.2 with different devices. Same problem in all cases. That works fine with Windows.

Steps to Reproduce:

1) Open file for writing via openAsync method.

2) Receive data from socket connection (as a client via Socket ProgressEvent.SOCKET_DATA event) and read it to temp ByteArray.

3) Write temp ByteArray to opened file.

4) Read FileStream "position" property (trace it, for example). There will be application crash.

I'd like to ask everyone affected by this issue to take a minute and vote for the following bug.

Thanks.

The same problem if you try to call addEventListener or close methods instead of read FileStream position.
So, async opened FileStream with writing bytes from Socket completely unusable with Android.
Please fix it ASAP.

I'm asking the team to take a look, does this still occur with the 21.0.0.150 beta?

Thanks,

Hi, Chris.

It works a little bit better with latest AIR 21.0.0.150 beta, but it still crashes.

Thank you for checking.  Our QA team has investigated and they were also able to reproduce.  We'll continue to work on this and keep the bug updated.
