Cannot connect devices, plus getting an error in Android O #37

Closed pratjosh9 closed 3 years ago

pratjosh9 commented 3 years ago

Cannot connect to groups.

In Android O, I'm getting an error "Operation failed due to an internal error"; after the location permission is provided.

The sample app was created from the example of usage from README.md. I've just added a view to output the contents of console.log.

Note:

  1. My repo containing the code can be found here
  2. The apk for the sample app can be downloaded from here

How do I connect two devices running this app? I'm not able to join any groups.

Hi @pratjosh9 As I can see from screenshot error happens in: https://github.com/pratjosh9/FileWarp/blob/master/App.js#L81

But in fact you call a lot of methods (from line 61 till line 82), such as: initialize, PermissionsAndroid.request, startDiscoveringPeers. From the error description, I may assume it's thrown by startDiscoveringPeers. Am I correct?

I tested it on Android O too, and everything was working fine.

By some reasons native method is throwing an error, with code 0. You can read here about it: https://developer.android.com/reference/android/net/wifi/p2p/WifiP2pManager#ERROR As you can see, there is no additional info, why it's failed. Would be really nice, if you could attach logs from logcat tool. in this case I can say more about your problem.

BTW do you see nearby devices from settings?

Hi @kirillzyusko

Thanks for the quick response.

I'll try to refactor the code to pinpoint the exact line resulting in Code:0 but most likely it is coming from startDiscoveringPeers.

Yes, I can see the wifi network created by createGroup in settings.

Here is the logcat of some operations on the app. I tried createGroup, removeGroup, getConnectionInfo, getGroupInfo operations.

@pratjosh9 Thanks for logs!

I have a question: do you have GPS enabled? I found this in logs:

Location mode is disabled for the device

From certain Android versions it's required to have GPS enabled in order to be able to discover P2P devices (I wrote about this requirement in readme: https://github.com/kirillzyusko/react-native-wifi-p2p#caveats)

@kirillzyusko Thank you for the support.

I enabled location and changed parameters to few calls that led to the sample app being functional.

I'm closing this issue since the problem has been resolved.
