loadWifiList() is returning a null wifiStringList even there are available connections !

[DinukaManohara]

RN 0.44.0 CLI 2.0.1 Android 7.0 EMUI 5.0 (Huawei GR5 2017) All the other methods are working perfectly but this loadWifiList() is returning a null list ???

@DinukaManohara Some android systems need to open up a list of the wifi available on the phone's GPS

@dan-me I'm having the the same issue. No list of wi-fi from method loadWifiList(). What should be added to make it work?

@jdeibe What is the version of Android? Do you have to open the phone GPS?

[jdeibe]

RN 0.45.1, Android 7.0, Honor from Huawei. I just noticed once I turn on GPS/Position from settings in my app it works. I would suggest to add code for permission to use GPS. I still don't understand why I need GPS permission..

Thanks @dan-me , we are already using this permission but this would help someone who is using this module.

@jdeibe We are using the following, and its working fine.

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

I had this same problem even after adding the permissions. Then I went into my app settings on my device and went into permissions. I realized that the "location" permission for my app was toggled to off. This permission did not even appear before I added the "ACCESS_FINE_LOCATION" permission, but for some reason it did not ask me to grant this permission in the app when I added it. I toggled it on in the settings and now i do get the list.

Edit: If you use the React-Native's PremssionsAndroid module and use PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION); the app will ask you if you'd like to grant permission in the app the next time you use it.

@SirNeuman Thanks! This was exactly my problem!

[tripflex]

Yup I can confirm this is specifically related to the ACCESS_FINE_LOCATION, which I only figured out through numerous trial and errors on a cordova plugin I forked for managing WiFi: https://github.com/tripflex/WifiWizard2/pull/8

[tolik85]

My app keeps crashing saying there's no ACCESS_FINE_LOCATION in the AndroidManifest, although it is there. Also, as @SirNeuman said, the location permission for my app in Android settings was toggled off and the app was not asking for user's permission with PermissionsAndroid.request(PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION);, but crashes instead (until I manually turn the location toggle on). Why is that?

Hi guys ! Anyone have solution about this problem ? I'm on Huawai, API 27

[ParthBarot-BoTreeConsulting]

I assume you have tried all the above permissions.

One thing you can check is, which version you are on and does it work for older Android versions? Like, we have tested this on Android 7, not sure in new versions!

Thanks

Hi @ParthBarot-BoTreeConsulting

Yes, you can see my AndroidManifest :

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

    <uses-permission android:name="android.permission.CAMERA" />
    <uses-feature android:name="android.hardware.camera" />
    <uses-feature android:name="android.hardware.camera.autofocus"/>

    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
