This is a spare time project that I work on my own time and pick to work what I want. You are free use the source code of this app with the conditions (GPL) that are attached to it but do not expect any support or anything that I do not feel like to provide.
The goal of this project is about providing an open-source OpenVPN app for Android. It is NOT about creating a library to be used in other projects.
If you build something on top of this is app you MUST publish your source code according to the license of this app (GPL).
This not personal against other developers or your software and projects. The reason that I am not helping or spending time to really into issues that are not part of this app itself is that this is just a spare time project of mine. The number of apps that use my code is quite large and the majority of them violates the license of my app. People create new apps that do not publish their source code.
I am just not willing to be the unpaid support for other people trying to make money of my code for free anymore. That is just not something I want to do in my spare time, so I tend to close these tickets quite quickly.
When the project started, I tried to help people but most people were just taking advantage of me and promises about open sourcing their app when they were finished were not fulfilled and I was just often ghosted when asking for the promises. Some people had even the audacity to come then back a year or two later and demand help with critical bug fixes when their app broke with some newer Android versions. Over the time, I simply lost confidence in people that were hesitant to share their source code and play with open cards.
That being said, I am happy to work together with people that are have are reproducing bugs in this app that they observed in their open-sourced fork to improve this app.
With the new VPNService of Android API level 14+ (Ice Cream Sandwich) it is possible to create a VPN service that does not need root access. This project is a port of OpenVPN.

If you want to develop on ics-openvpn please read the doc/README.txt before opening issues or emailing me.
Also please note that before contributing to the project that I would like to retain my ability to relicense the project for different third parties and therefore probably need a contributer's agreement from any contributing party. To get started, sign the Contributor License Agreement.
Even if you are no programmer you can help by translating the OpenVPN client into your native language. Crowdin provides a free service for non commercial open source projects (Fixing/completing existing translations is very welcome as well)
You can find the FAQ here (same as in app): https://ics-openvpn.blinkt.de/FAQ.html
There is the AIDL API for real controlling (see developing section). Due to high demand also acitvies to start/stop, pause/resume (like a user would with the notification) exists
de.blinkt.openvpn.api.DisconnectVPNde.blinkt.openvpn.api.ConnectVPNde.blinkt.openvpn.api.PauseVPNde.blinkt.openvpn.api.ResumeVPN
They use de.blinkt.openvpn.api.profileName as extra for the name of the VPN profile.
You can use adb to to test these intents:
adb -d shell am start -a android.intent.action.MAIN -n de.blinkt.openvpn/.api.ConnectVPN --es de.blinkt.openvpn.api.profileName myvpnprofile
You make your life and that of your users easier if you embed the certificates into the .ovpn file. You or the users can mail the .ovpn as a attachment to the phone and directly import and use it. Also downloading and importing the file works. The MIME Type should be application/x-openvpn-profile.
Inline files are supported since OpenVPN 2.1rc1 and documented in the OpenVPN 2.3 man page (under INLINE FILE SUPPORT)
(Using inline certifaces can also make your life on non-Android platforms easier since you only have one file.)
For example ca mycafile.pem becomes

The old official or main repository was a Mercurial (hg) repository at http://code.google.com/p/ics-openvpn/source/
The new Git repository is now at GitHub under https://github.com/schwabe/ics-openvpn
Please read the doc/README before asking questions or starting development.
