gnirehtet and android 8.1

[bfcosta]

Does gnirehtet work with android 8.1? I can't get mine working with it. The problem might be the VPN connection or something else.

Yes, it should. What's the problem? Check adb logcat.

Java gnirehtet log says this in the first run:

2019-05-17 22:44:51.483 INFO Main: Starting relay server...
2019-05-17 22:44:51.484 INFO Relay: Relay server started

2019-05-17 22:44:54.494 ERROR Main: Cannot start client: Command adb ["shell", "dumpsys", "package", "com.genymobile.gnirehtet"] returned with value 1

Then, it says this in the second run:

Adb logcat says lots of things, but basically repeats this java null pointer exception.

Well, if it was not clear by my last comment, no connection was possible. Also, I used the rust binaries, not the java jar file.

Same problem on 8.1.

No confirmation dialog when VPN set up. No sign that VPN is set up. App on phone never started.

console output from bat on windows pc...

@bfcosta

basically repeats this java null pointer exception
this NullPointerException comes from another program (com.floriandraschbacher.reversetethering.free).

This issue is another case of no dialog displayed.

Some devices require to "authorize" the app manually, but each in different ways. See for example: #161 (comment) and #150 (comment).

[bfcosta]

I have checked all possible configurations in android settings and could not find any way to "authorize" the app manually. I wonder if there is a way of doing it using adb in the command line. GooglePlay might be able to do it but it does not recognize gnirehet as an app.

[rom1v]

Should be fixed by f868180.
