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): http://ics-openvpn.blinkt.de/FAQ.html
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
<ca>
-----BEGIN CERTIFICATE-----
MIIHPTCCBSWgAwIBAgIBADANBgkqhkiG9w0BAQQFADB5MRAwDgYDVQQKEwdSb290
[...]
-----END CERTIFICATE-----
</ca>
Please note that OpenVPN used by this project is under GPLv2.
If you cannot or do not want to use the Play Store you can download the apk files directly.
