SimpleRT stops working after device reboot

Hi,

I am using SimpleRT for a Samsung Galaxy S7 with Android Version 7.0 connected to a Raspberry Pi 3 with Raspbian as the Host.

I have downloaded your provided apk and installed it via adb install

Reverse tethering is working fine until I restart the android device. After the restart, SimpleRT on the Pi is telling me that reverse tethering is working again but the android device is unable to get an internet connection.

This problem is resolved after I enable wifi on the android device, let the device connect to a wifi hotspot and then disable wifi again. Afterwards, reverse tethering can be used again.

This is the complete rt debug output.

Just a quick update:

It looks like the android device does have internet after a restart. It just doesn't know about it.

Because I can ping 8.8.8.8 from within the adb shell. The Samsung Galaxy S7 probably doesn't even try to connect to a website in the browser. I assume it believes that it can't possibly have internet because it never connected to any network. For some reason, connecting to a network once and disconnecting afterwards solves this issue...

I can also ping www.google.de from within the adb shell. So it's not a dns problem.

I see that you write in your Readme.md: "Issues: Some apps do not recognize the reverse tethered internet connection due to ConnectivityManager policy. Just leave WiFi or 3g connection active, connection will go through SimpleRT anyway."

So I guess you are already aware of this issue. Therefore, I am closing this issue.
