+Building on Android
+---------
+
+This is a small guide to help you run civetweb on Android. Currently it is
+tested on the HTC Wildfire. If you have managed to run it on other devices
+as well, please comment or drop an email in the mailing list.
+Note : You dont need root access to run civetweb on Android.
+
+- Download the source from the Downloads page.
+- Download the Android NDK from [http://developer.android.com/tools/sdk/ndk/index.html](http://developer.android.com/tools/sdk/ndk/index.html)
+- Run `/path-to-ndk/ndk-build -C /path-to-civetweb/build`
+  That should generate civetweb/lib/armeabi/civetweb
+- Using the adb tool (you need to have Android SDK installed for that),
+  push the generated civetweb binary to `/data/local` folder on device.
+- From adb shell, navigate to `/data/local` and execute `./civetweb`.
+- To test if the server is running fine, visit your web-browser and
+  navigate to `http://127.0.0.1:8080` You should see the `Index of /` page.

+
+Notes:
+
+- `jni` stands for Java Native Interface. Read up on Android NDK if you want
+  to know how to interact with the native C functions of civetweb in Android
+  Java applications.
+- TODO: A Java application that interacts with the native binary or a
+  shared library.
