+Install the [Android NDK Revision 10d](https://developer.android.com/tools/sdk/ndk/index.html) for 64-bit OS X:
+
+    brew install android-ndk
+
+Install [Android Studio](https://developer.android.com/sdk/installing/studio.html) and the Android SDK:
+
+    brew cask install android-studio
+    android
 
-Install the Android SDK. We recommend doing this by way of [Android Studio](https://developer.android.com/sdk/installing/studio.html). To install it, open Android Studio. By default, the SDK will be installed to `~/Library/Android/sdk`. In case you get an error message telling you that it can't find a JVM, it's because you installed a custom Java VM from Oracle. Follow [these instructions](http://tools.android.com/recent/androidstudio1rc3_releasecandidate3released) to start Android Studio. Make sure all environment variables are absolute; don't use `~` to indicate the home directory.
+Install the Android SDK by opening Android Studio. By default, the SDK will be installed to `/usr/local/opt/android-sdk`. In case you get an error message telling you that it can't find a JVM, it's because you installed a custom Java VM from Oracle. Follow [these instructions](http://tools.android.com/recent/androidstudio1rc3_releasecandidate3released) to start Android Studio. You'll wind up setting these environment variables in your .bash_profile or similar:
 
-    export ANDROID_HOME="/Users/username/Library/Android/sdk"
+    export ANDROID_HOME=/usr/local/opt/android-sdk
+    export ANDROID_NDK_PATH=/usr/local/Cellar/android-ndk/r10d
+    export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk
 
 Run:
 
     make android
+    open -a Android\ Studio
 
 You can then open `android/java` in Android Studio via "Import Non-Android Studio Project".
