App network access denial causes app to crash

John564479

Hi,
I have noticed that some apps does not work (app crashes and does not launch) if the network access is denied. One example is the GBA emulator "pizza boy" from google play. Does anyone know why this happens?

John564479 logs might help determine the cause. I don't recall any apps on my phone crashing when the network permission was not granted.

Any update om this?

It should say swich emulator "yuzu" not "pizza boy" in my question*

Probably9857

Hmm....looks like it is trying to open a socket to broadcast UDP packets, and it is not being allowed to do that...

This is just a guess, but if you are on the 2024091700 release, maybe updating to 2024091900 will fix this.

GrapheneOS

Probably9857 It's unrelated.

Probably9857

Or maybe you just need to grant Network permission, although I would expect the app to handle the lack of a network connection more gracefully than this.

GrapheneOS

Probably9857 The app isn't doing error handling but rather crashes when it gets an error.

Probably9857

Another thing you could try, just as an experiment:

Put your phone in Airplane Mode and wifi off. Grant Network permission. See if you get the same error.

Not a solution, but might provide some useful information to understand what's going on.

yore

Grant the app the Network permission, then force stop it and clear all cache and data. Turn on Airplane mode and disable Wi-Fi. Launch the app. If your problem persists, then we can confirm it's most likely a problem with the app.

GrapheneOS

yore No, since the Network permission prevents creating the socket including one for the loopback interface. We made changes to improve compatibility by returning standard I/O errors at the Java layer, not running network-dependent jobs, pretending the network is down in a bunch of APIs, etc. but apps still need to handle errors properly. It's possible for buggy apps to be incompatible with it but not the external networks being down. It's also possible for apps to genuinely need the loopback interface. In the future we could use network namespaces to isolate loopback for apps to the profile or specifically to the app but that's quite far from something we can do soon.

yore

GrapheneOS I wasn't aware of that. Thanks for clarifying.

GrapheneOS

Alright cheers for getting back to me regarding this. I can also confirm that the app does still work if WiFi is disabled as you mentioned.

I have noticed the same/similar issue on some other apps as well (cant recall the names as I just uninstalled them) so it would be great if it gets fixed in future updates.
