+# Dependencies
+
+Install Android Studio. I installed version 3.5.2.0 via the `Ubuntu Software` app, which installs a `snap` version. This is a 700Mb download, and snap will likely keep 2 or 3 version of it. 
+
+If there is no prepackaged version for your OS, you can download it directly from [here](https://developer.android.com/studio).
+
+Set ANDROID_HOME environment variable. Add it to ``.bashrc`` or ``.profile``. 
+
+Accept the Android SDK licenses:
+
+```bash
+jon@hpjon:~/Android$ $ANDROID_HOME/tools/bin/sdkmanager --licenses
+Warning: File /home/jon/.android/repositories.cfg could not be loaded.          
+5 of 5 SDK package licenses not accepted. 100% Computing updates...             
+Review licenses that have not been accepted (y/N)? y
+
+...
+```
+
+If you then launch Android Studio, it gives a warning that no SDK has been found and gives you the option to install one. I accepted the defaults and it installed Android 29. 
+
+
+
+
+----
+
+Clone the repository:
+
+```bash
+jon@hpjon:~$ mkdir Android
+jon@hpjon:~$ cd Android
+jon@hpjon:~/Android$ git clone https://github.com/mosaicnetworks/babble-android.git

+
+----
+
+Open the babble-android project within Android Studio. 
+
+
+## Build the aar library
+
+First some dependencies:
+
+Install the Android NDK. Instructions are [here](https://developer.android.com/ndk/guides/index.html).
+
+In Android Studio, Tools/SDK Manager. Under the SDK Tools tab, choose to install LLDB, NDK(Side by side) and CMake. 
+
+In a terminal session, clone Babble. 
+
+```bash
+~/Android/Sdk/ndk$ ln -s 20.0.5594570/ latest
+
+$ go get golang.org/x/mobile/cmd/gomobile
+$ go get golang.org/x/tools/go/packages
+$
+$ cd [...babble]/src/mobile
+
+$ export ANDROID_NDK_HOME=$ANDROID_HOME/ndk/latest
+$ gomobile init 
+$ gomobile bind -v -target=android -tags=mobile .
+$ mkdir -p build/test ; mv mobile.aar mobile-sources.jar build/test
+``
