JAVA Speech SDK 1.16 crashes if there is no connection

[matecode]

With version 1.16 the java library crashes if there is no network connection. i'm using it on an android device.

Reproduction:
Check out Sample Project and change directlinespeech modules build.gradle to
implementation 'com.microsoft.cognitiveservices.speech:client-sdk:1.16.0'

Run without any network connection on device

Logcat:
A/libc: Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x0 in tid 24001 (Thread-4), pid 23963 (irtualassistant)

@matecode thanks for reporting this! Can you please check to see if this also happens with version 1.15 or earlier?

@dargilco Sorry, i forgot to mention: It does not happen in version 1.15

[dargilco]

@matecode, thanks for confirming. Let me follow up on it and I’ll post an update here as soon as I have it.

[dargilco]

Okay did some more investigation and it is a bug in Speech SDK after all. This is a regression in Speech SDK version 1.12, as I can run the Android sample with version 1.11 and get the cancelation event as expected (when I use wrong Speech Key). When I do the same with version 1.12, there is a crash. I do not get a cancelation event.
@matecode I opened a high-priority bug in our internal system and we will be looking at it.
To keep the list of open issues here fresh, I am closing this issue, but will continue to update here with your findings.
Thanks,
Darren

I checked version 1.15 and 1.16, and in my own project which is different to the sample i have a crash with 1.16, but not with 1.15

@matecode what is the Android device you are using and what Android version does it run?

[matecode]

@dargilco I tested with Android10 on a Nokia 7.2 and also with Android11 on a SamsungS20+

this is the logcat output from the VirtualAssistantClient Sample on the S20+:

Thanks!

@matecode The crash in Speech SDK was fixed and will be available in the next public release. Thank you again for reporting this! I also noticed that the Virtual Assistant sample code blindly tries to re-create the DialogServiceConnector session on every cancelation event, including no network connection or bad speech keys, which is probably not a good idea as this just results in an infinite loop of re-creating the session. It should simply display the error and stop. I'll file a bug on the Bot-Framework solution team to fix the sample code. I will close this issue.
