Connect Problem about simpleopenvpn-android

[nnjun]

Are you sure the connection has been successful? If the connection is inexplicably disconnected after success, then it is recommended to pay attention to the server log!

Hello nnjun, thanks for the hard work.

It connects then exits when getting to the "Getting client config" part.
I didn't change anything but the data string.
I'm getting the connection closed for some reason.

logcat:

OpenVPN: Starting openvpn

OpenVPN: OpenVPN process exited

TAG: 连接关闭

OpenVPN: Exiting

This is the server log:
My config is okay,
My credentials are okay,
The server recognizes it as normal.
If you connect to the server with a regular client then exit it, it produces this same log.

Any idea why?

peer-id 0' (status=1)
Connection reset, restarting [0]
SIGUSR1[soft,connection-reset] received,
client-instance restarting

[nnjun]

Hello, there are many reasons for this. What I've encountered is that two clients use this configuration at the same time, resulting in crowding out each other. If you don't have this situation, it's advisable to sort out other problems. Google searches for "openvpn Connection reset, restarting [0].

[yunolawliet]

I've already done that.
I've solved the problem by using https://github.com/micer/openvpn-sample-app
Module instead, and porting your VPNActivity with it.
The problem now is the service isn't working properly.

[yunolawliet]

Okay, managed to port everything now including the VPNService.
I don't know what actually is wrong, micer's module is much older than what you are using, nonetheless thank you so much. It's really hard to find a good OpenVPN for android source and you got one. It actually helped me a lot in understanding the process core of Schwabe's openvpn. Also the VPNActivity is just a genius class, made my life easier. thanks!

[nnjun]

Yes, it's hard to find the right code for OpenVpn, and I'd like to make it easier for people in trouble. Demo is the most basic connection. In fact, OpenVpn involves much more than you might think. We should expand it. Of course, the original intention of this library is to make it more convenient. For expanding or more functions, developers can explore for themselves. He's much stronger than we thought!

@yunolawliet can share what you do please , i have same problem as you

[yunolawliet]

@yunolawliet can share what you do please, I have the same problem as you

@coderzstas I suggest you get a module from an openvpn android client and follow these steps:
Import module,
Import nnjun's VPNActivity and Service to it.

The problem I have right now is with the notification.
When I click it doesn't show the app.
Must be a binding problem, I yet to still solve.

@nnjun He has the same problem as mine, any idea?

[nnjun]

I've added support for him and a new way of listening. See Readme for details. I have updated the code! @yunolawliet

[yunolawliet]

@nnjun great, I've tested the intent part and it works. Any idea on how to preserve the app while the service is running? The app keeps closing while the server is alive.

[nnjun]

Do you mean that the back-end service of the application has been killed by the system? @yunolawliet

[yunolawliet]

@nnjun Yes. But the a better approach would be checking if the service is running. So if the system killed the back end, you can adjust the layout. Or my approach is wrong? Do you have a better idea? Also, it's nice that you made the code neat. Also having access to the state and it's equivalent strings would be great.

@yunolawliet Firstly, mobile ROM is involved. Different manufacturers have different limitations. Secondly, we can adjust the parameters of the server, such as keepalive 10 120. We can slightly shorten the Ping time to enhance connectivity. For example, keep alive 5 120, more still need to look at mobile phones.

[yunolawliet]

@nnjun got it. Thank you. Loving your module so far. :)

[nnjun]

@yunolawliet Thank you. Remember to pay close attention to me. Ha ha ha ha ha ha ha
