findAndConnect restarting the phone and crashing the app

[shihabus]

As a workaround for connection verification I have used NetInfo API. But when I use the findAndConnect method to connect, it crashes the app and restarts the device. What can be the reason for this odd behavior?

Which version of Android are you using?

[shihabus]

I was using Oreo, which version 8.0+. But in lower version, the findAndConnect was not crashing.

Hi @shihabus , have you request user permissions? request permissions Check issues #49, #47

Can you reproduce the bug with the app Example ?

@shihabus we use NetInfo as well #2

[shihabus]

The problem with using NetInfo is that, connectionChange togles muiltiple times on connecting. It is hard to derive a pattern so as to understand whether the connection was successful or not. Can anyone help me on this? @devstepbcn I am requesting permission but not access-coarse-location. I will try this and let you know.

@btav I was using Nougat and Oreo. In Nougout it was fine, in Oreo the app gets crashed and phone reboots.

@shihabus I don't use NetInfo as well. I am just periodically calling getSsid() and it works good.

@gigby That workaround makes sense. So u call getSSID() how frequent? You have any input on, why wifiList returns empty string? This is a recent issue, previously when I was using the lib, this behavior was not there.

@shihabus exaple of using getSSID(): async waitingForIsConnectionRight(multiplier) { let res = false; let counter = 5; const time = 1000;

const delay = multiplier ? multiplier * time : time;

do {
  counter -= 1;

  /* eslint-disable no-await-in-loop */
  res = await new Promise((resolve) => {
    setTimeout(() => {
      resolve(this.isWifiConnectionRight());
    }, delay);
  });
} while ((counter > 0) && !res);
/* eslint-enable no-await-in-loop */

return res;

}

Getting wi-fi list: setWifiNetworks = async () => { const data = await new Promise((resolve, reject) => { wifi.reScanAndLoadWifiList((wifiStringList) => { resolve(filterDuplicatedNetworks(JSON.parse(wifiStringList))); }, (error) => { reject(error); }, ); });

this.setState({
  data,
  loading: false,
  isFormShowed: false,
});

};

These functions work well on almost all devices on Android 7 and 8. I checked few days age this library after last updates (they fixed android 8 connection). It works well

@gigby Thanks!!!

_handleConnectivityChange = async (isConnected) => { // ==== let connectionInfo = await NetInfo.getConnectionInfo() this.props.connectionStateChanged(isConnected) this.props.connectionTypeChanged(connectionInfo.type) // console.log('Type',this.props.connectionType) // console.log('State',this.props.connectionState) };

  }

}, 5000); }

@gigby the method I follow is, after trying to connect with WifiManager.connect() I try to watch NetInfo. If the state changes, I try to get SSID and try to see if it matches the SSID I tried to connect.

@devstepbcn can u fix the Connect() method.
