Android companion app crashes when attempting to open

cameron · 2017-12-23 17:21:16 UTC

Device: LGE Nexus 5X
Android 8.1.0 (API 27)

How to reproduce:
I just installed the Misty companion app from Hockey. I attempt to open the app and it crashes right away. I’ve tried restarting my phone and then opening the Misty companion app again and get the same crash.

Here are the error logs from logcat in Android Studio:

Found this post about a very similar error. Might be helpful:

Krystin · 2017-12-23 17:41:23 UTC

Hi, Cameron. I am at about the same point and hitting the same issue.

cameron · 2017-12-23 17:42:13 UTC

Actually this post seems to have a better fix:

cameron · 2017-12-23 17:45:07 UTC

“Disabe Use Shared Runtime from Project ->Options->Android Options”

Then re-build the app and deploy.

No idea if it will actually help, but sounds like a good thing to try.

Ben · 2017-12-23 18:51:56 UTC

Yay for consolidation and solidarity?

morgan · 2017-12-23 19:15:06 UTC

I’ve published a new build to Hockey, hopefully resolving the crash

Krystin · 2017-12-23 20:12:00 UTC

Unfortunately, not. The crashing persists.

cameron · 2017-12-23 22:54:08 UTC

I installed the latest version and unfortunately it does not work for me either. Tried on the 2 devices mentioned earlier, and then also installed on a Nexus 9 tablet with Android 7.1.1 and the same crash.

logcat looks the same as before:

cameron · 2017-12-23 22:55:39 UTC

If you guys can get the TestFlight invites working I would be happy to give things a shot on iOS.

cameron · 2017-12-30 00:33:26 UTC

I was able to install and open version 1.0.8 (8) of the Android Misty Companion app on my phone with Android 8.1.0!

I was also able to connect to my Misty! I haven’t been able to set the wifi network on Misty - I get an error each time - but this may be because it’s 5Ghz. Will play around with this and see if I can get it on 2.4Ghz.

The bluetooth connection to my Misty seems to drop very quickly. Driving has only worked a little - it gets stuck on the first command sent - so it ends of driving in a circle until I turn Misty off and on again. I will keep playing!

cameron · 2017-12-30 00:48:33 UTC

I should mention for others, I had to manually uninstall the earlier version of the Android app before it would successfully install version 1.0.8(8).

cameron · 2017-12-30 03:01:02 UTC

I have now been able to set the network connection on my Misty and send it commands via wifi using the sample index.html file in the Api Client - just like we did at the Robothon! Wohoo!

The documentation doesn’t explicitly mention what port value is supposed to be used. The default value in the index.html is “2010” - which works. This might be worth noting in the docs.

justin · 2017-12-30 20:52:24 UTC

Hey Cameron and/or Krystin,

I think the error you were seeing earlier regarding the API Level for the Companion App is an issue with the Bluetooth API compatibility. On Android 5.0 the Bluetooth LE API completely changed (for the better) and our app uses the new APIs. So while the app will install on 4.4 the Bluetooth APIs are incompatible. I’m looking into solving this issue but we don’t have a great work around as of right now. Sorry about that, I’ll keep you updated on progress.

Thanks!

cameron · 2017-12-31 00:56:28 UTC

@justin Perhaps, but I experienced the same error on my devices with Android 8.0.1 and Android 4.4.2. Anyway, the latest version of the companion app seemed to resolve the issue.
