Android 10 support. Testers needed

[ThanosFisherman]

Please report any connectivity issues related to Android 10 here.

WiFiUtils now has a basic support for Android 10 thanks to the contribution #46 of @eliaslecomte

Hopefully owners of Android 10 devices will help us fix potential bugs.

Does it have a way to connect to Wifi network as I've written here:
#31 (comment)
?
At least via root?

[ThanosFisherman]

@AndroidDeveloperLB I haven't tried the root way because that's another story that involves some command line arguments plus I'm not even sure if it's gonna work.

The new contribution aims to make this library connect to WiFi networks on Android 10 devices without requiring root but it's not thoroughly tested yet.

[AndroidDeveloperLB]

@ThanosFisherman Wait you have an idea of what should be done using root?
As for without root, I only know of a "suggestion" API that Google presented. It has various disadvantages:

1. Not staying forever. If the app is removed, the networks too.
2. Has some limit of number of networks, though it's a very high limit.
3. Last time I checked, the API causes a notification to appear, instead of just adding the networks or even show a confirmation dialog to the user to add them. Not only that, but it didn't appear right away. It might have changed since I checked it though.

[eliaslecomte]

That is correct, with the new api (starting Android 10), the wifi internet is only for the app that requested it. I assume the use case is more like connecting to configure IoT devices.

[AndroidDeveloperLB]

@eliaslecomte Well it's not such a nice alternative to what we had before...

[RussNelson]

I believe that they're trying to prevent MITM attacks by not allowing an app to connect to a subverted access point. They don't explicitly say that because you never want to give attackers suggestions.

[AndroidDeveloperLB]

" subverted access point" ?
So it's not about privacy of getting location by knowing the surrounding Wifi networks?

[RussNelson]

No, that's why an application can't connect without recommending the connection to the user.
The added permissions needed to scan are about getting location by knowing the surrounding WiFi networks. By insisting on both COARSE_LOCATION and FINE_LOCATION, it becomes a moot point that you can look up the location via WiFi. The user has to trust your app with your location because .... you can figure it out on your own.

[AndroidDeveloperLB]

What I say is that without COARSE_LOCATION and FINE_LOCATION permissions, it's still possible to get a good guess of where you are, so that's why I think they added those into the mix.

[RussNelson]

Yes, you are quite correct. So rather than leave the user in the dark, they require scanning for WiFi access point to have location permissions. The user gets explicitly asked for that.

I tried implementing the same in a new project. The phone connects and instantly disconnects to the network, as the OnAvailable method of the NetworkCallback seems to be in a loop. Demo video

[AndroidDeveloperLB]

@singhal2 Can you please share the source code of this?
Maybe it's a bug on the OS

What network security is used (wpa2?)?
Is it a network with or without internet?

[singhal2]

WPA2 and with internet. I’ll upload a sample soon.

@singhal2 If you can make it happen even without this library, you should report it to Google:

Is your app targetting Android 10? If that's the case it's not actually saving the wifi configuration. You can only Disconnect in wifi settings but it's never saved in the first place. I would call the remote method first.

[super0610]

min sdk version is 23, targetSDK version is 29

[ThanosFisherman]

Regarding the sample I did some cleanups, migrated to .kts gradle scripts, renamed the MainKotlinActivity into MainActivity and removed the old Java MainActivity. The sample should work as is. Just make sure you are using the latest Android Studio Version (CC @mas1515 )

@super0610 Seems like another restriction (or probably a bug on Android OS itself). You say that if you manually forget the network then WifiUtils are able to reconnect with the new password. Please Try the following:

• Make sure the hotspot you are trying to connect to is not previously saved in the device. If it is then manually forget it from the Settings
• Open the sample and try to connect with the current password (This step should work fine)
• Now change the HotSpot password via your router firmware
• Launch the sample again and choose REMOVE - Let me know at this point if the network is actually removed from the Settings
• Modify the Wifi password in sample code to the new one and rerun the sample
• Turn off and back on your device's wifi (just in case there is a glitch or something)
• Try to connect again with the new password - Let me know what happens at this point

[super0610]

Thanks for your reply @ThanosFisherman
Yes, I am using latest Android Studio, and latest WifiUtils library (1.6.3)
I will check this in few hours and share here.
Best Regards.,

[super0610]

hi @ThanosFisherman
I tested with the Sample, but the sample doesn't work.
I tried same credential for the wifi, forget wifl from settings.
Tested several times, but sample didn't work, and our app works with same credential.

[super0610]

in Android 7, sample works.
in Android 10 (mine is Samsung SM-T290 tablet), it doesn't (Timeout)

[ThanosFisherman]

Thanks for the update @super0610 I'm not sure yet what might be wrong or if this is an intended behavior. I'll try to investigate it and post back.

[super0610]

Thanks @ThanosFisherman
I will wait good news, and i can test in my side if needed.

[eliaslecomte]

I'm not having a Samsung SM-T290, so I can't help on this one. If you could do any more debugging @super0610 that would be awesome.

Getting Error COULD_NOT_SCAN in android 10 when connecting to local hotspot created with specific ssid and password

Getting Error COULD_NOT_SCAN in android 10 when connecting to local hotspot created with specific ssid and password

Same here. Galaxy S20 connecting to a device that doesn't have an internet connection with a specific ssid and password.

edit: could be an S20 specific issue. I am able to connect to the same WiFi network using Google Pixel 4a on AN10

edit 2: location was turned off on the S20. Turned it on and was able to connect

[OneupLee]

I have found an application and it can easily connect to wifi on android 10 device.But I don't know how it work.

About enabling/disabling Wifi through the library on Android 10 (and up) - I think because of the OS restrictions that have been put in place the best option would be to invoke a Settings panel:

val panelIntent = Intent(Settings.Panel.ACTION_WIFI)
startActivityForResult(panelIntent, WIFI_REQUEST)

What do you think?

This is logic you want to add in your app :-). The library indicates wifi is off. You show this 'error state' and the user has to take action. You can add a button that then opens the Settings screen.

[ansuman87]

I tried it on my Android 10 device and I get zero scanResults.

[ImBIOS]

It's probably because location permission that is not permitted maybe due to reinstalling the app. I have same issue and resolved it like this.
