When building release apk, opening app crashes :

signal 6 (SIGABRT), code -6 (SI_TKILL), fault addr --------
Abort message: 'art/runtime/thread.cc:1350] No pending exception expected: java.lang.ClassNotFoundException: Didn't find class "org.strongswan.android.logic.CharonVpnService$BuilderAdapter" on path: DexPathList[[zip file "/data/app/vpn-1/base.apk"],nativeLibraryDirectories=[/data/app/vpn-1/lib/arm, /data/app/vpn-1/base.apk!/lib/armeabi-v7a, /vendor/lib, /system/lib]]'

Whenever i am trying to connect to any VPN server using this plugin getting unreachableError as status and unable to connect to any VPN. I pinged those servers and checked, they are working fine.

could you make it support ios？

Nice library. But i am getting

 Unhandled Exception: PlatformException(PrepareError, Failed to prepare, false)

when running from vs code.

The app opens and a dialog appears but it is dismissed automatically. Then the error is encountered.

Please the solution !

这个，这个，GPL开源的。虽然我打算构建的app也是要GPL开源。但是为了这个库能够被更多人使用，开源协议使用LGPL会更好一些。
作者若是坚持的话，请直接关闭这个issue。

openvpn server is it possible to use?

I am trying to use free accounts sush as
us.freeikev2vpn.com but i got a notification that says "unreachable server ".

Vpn is working is Android. However I've tested in iOS device, in the xcode it says

VPN started successfully..

But the state doesn't change, it's still FlutterVpnState.disconnected. Then when I put the app in the background to try to browse a webpage I get the error below.

2020-04-20 14:24:32.864656+0800 Runner[17084:9649796] Can't end BackgroundTask: no background task exists with identifier 1 (0x1), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.

On integration it gives error,
java.lang.IllegalArgumentException: Service not registered: io.xdea.flutter_vpn.FlutterVpnPlugin$_serviceConnection

If VPN is in connected state, on pressing back 1-2 times on android, it stops VPN connection.

Or how can ikev2 be used without a certificate?

Note: C:\src\flutter\.pub-cache\hosted\pub.dartlang.org\flutter_vpn-0.6.1\android\src\main\java\org\strongswan\android\logic\NetworkManager.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details.

i want to know how to setup vpn server on ubuntu 16.04. thanks

Is it possible?

Hi guys, this is more like a question, was wondering if there are any plans or work in progress to add support for certificate base authentication e.g. p12 like the current official StrongSwan Android app supports.

Cheers,

When pressing back button on the app brings to home screen and crash.

It says:

App keeps stopping

Unable to destroy activity com.myapp.testvpn/com.example.testvpn MainActivity):
java.lang.IllegalArgumentException: Service not registered: io.xdea.flutter_vpn.FlutterVpnPlugin$

_serviceConnection

if in debug mode, the application can be run, but when in release mode the application cannot be opened

The connection disconnects when I close the VPN app from the the Android's recent applications menu. And the notification state changes to "connecting...".

It is necessary for a VPN to keep working even after the app closed. I have tested the original strongSwan Android app. The connection works even after closing the app. Any idea on how to keep the connection alive in the background?

Is there a way to set custom mtu size?

when build iOS on Catalina, it will fail with error message that SWIFT_VERSION is missing,

it can be fixed by add below lines in flutter_vpn.podspec

  s.ios.deployment_target = '8.0'

  #added to make it working for iOS
  # Flutter.framework does not contain a i386 slice. Only x86_64 simulators are supported.
  s.pod_target_xcconfig = { 'DEFINES_MODULE' => 'YES', 'VALID_ARCHS[sdk=iphonesimulator*]' => 'x86_64' }
  s.swift_version = [ '4.0', '4.1', '4.2', '5.0', '5.1' ]
  

so please fix this in next release.

Hi, I am facing a problem when building release apk.

FlutterVpn.prepare();
FlutterVpn.onStateChanged.listen((s) => setState(() => state = s));

hello . i am using this package in my app but i found a problem ...
the onStateChanged is not working in IOS platform. (it works perfectly in Android platform).
how can i update my State in IOS platform when Vpn is Connected?? what is your suggested approach ???

I tried to run the example in vs code but it does't work

hi,
i encountered a problem in ios platform.
i connect to vpn and get the state of connection using "FlutterVpn.currentState" and it works fine.
but when i exit the app while vpn is still connected, and then open it again, the "FlutterVpn.currentState" function returns "FlutterVpnState.disconnected" while the vpn is still connected.

Hello, I don't know how to set the CA certificate in the program, can you tell me, thank you!

Please, I have a file .opvn and port(TCP) , was wondering if you could tip me , connect vpn
thank you!

hello

how can i determine the connection type ? for example L2TP or PPTP .
and what is the default connection type ??

Do you have plans to support wiregaurd ?

I added the ndk filters as described on read me.

However when I build appbundle and run it on pixel 2 , it crashes on start up

drops java.lang.UnsatisfiedLinkError coudln't find libflutter.so

Ok, just installed strongswan, did some configs, was wondering if you could tip me, for multiple users, is it better to use same credentials or new one per each. and how so?
About the app, just tried it, there is the start notification after connection, now if you disconnect and exit the app, the star remains up the notification area, is there a way to control that?
