Hotspot in Android 11

[ahadobas]

Hi,
My phone has freshd itself to Android 11.
I installed the latest version 5.1.
But at "Wi-Fi hotspot" setting got "Not supported for Android 11+" message.
It worked on Android 10 with Google Play version.
How can I get back the switching opportunity of hotspot on my phone?
Thanks.

Yes this is probem. I do not found solution for Android 11+. Maybe solution is with PhoneProfilesPlusExtender. Or root. I will looking on it. And maybe will be resolved in next version.

Maybe solution is with PhoneProfilesPlusExtender.

Nothing has changed after installing this one :(

Or root.

I don't want to root because of my mobilbank app :(

I will looking on it. And maybe will be resolved in next version.

I'm waiting for it :)

"Maybe solution is with PhoneProfilesPlusExtender.

Is not implemeted. I must implenet it ;-)

Hm:

"If using Android Version >= 11
You can start a hotspot with TetheringManager#startTethering code here. Here is an example from the official docs on usage.
Similarly, there is a TetheringManager#stopTethering method with code here. This will stop a hotspot."

But these methods are marked with: @SystempApi. Application must be installed as system application. :-(

Only solution is emulating user clicks to device Settings as for "Force stop application". But this si complicated, because of changes in Settings GUI in various devices. :-(

Other apps like
MacroDroid - Device Automation

And
Automate
https://play.google.com/store/apps/details?id=com.llamalab.automate&hl=en&gl=US
support this

My device is rooted

Hm hm. MacroDroid working. Tested in my non-rooted Galaxy S21. Only problem is with Wi-Fi off (not working), even when I install latest MacroDroid Helper apk.

My, in Android 10 working version not working in Android 11. Returned is:

java.lang.NoSuchMethodError: No interface method startTethering(ILandroid/os/ResultReceiver;ZLjava/lang/String;)V in class Landroid/net/IConnectivityManager; or its super classes (declaration of 'android.net.IConnectivityManager' appears in /system/framework/framework.jar!classes2.dex)

IConnectivityManager is changed in Android 11. :-(

I must search for solution.

Does this help?

[henrichg]

Yes, I was readed it.

Problem is with this: TetheringManager#startTethering() and TetheringManager#stopTethering().

1. I must use java reflection for running it. Because for compile android sdk 29 (used in PPP) class TetheringManager not exists.
2. Problem is with StartTetheringCallback callback parameter. This interface not exists in compile sdk 29.

In MacroDroid is not needed root to enable hotspot. And its compile sdk is 30+. :-(

PPP uses this, to call android hidden api: https://github.com/anggrayudi/android-hidden-api
But for compile sdk 30 is in android.jar bug. It generates error when I build PPP. By me, I must wait for fix.

News: I can build with compile SDK = 30.

This problem is resolved:
