Published: November 13, 2016

Updated: November 14, 2016


Goal: Share how to set up re-natal v0.3.x (i.e., cljs + reagent + re-frame + figwheel + react-native) on Ubuntu 16.04 LTS for android application development.


  • Clean install of Ubuntu 16.04 (not in a VM)
  • 25 GB of disk space (with everything installed, I used 21.8 GB of disk space)
  • 16 GB of RAM (with everything running, I used 8.4 GB of RAM)

Step 9: Download android studio

Download some 32 bit stuff.

sudo apt-get install -y libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1

Download android studio here, and unzip it. Note, your version may vary.


Run android studio:

cd android-studio/bin/ && ./

Select I do not have a previous version of Studio or I do not want to import my settings. and then click Ok.

A welcome page will appear, click Next.

For install type, choose Standard, then click Next until you get to Finish and click that. A bunch of things will get installed, then click Finish again.

At this point, you should see the standard welcome screen when you launch Android Studio. At the bottom, click configure, then click SDK Manager. It should open with Andorid SDK highlighted in the left bar. In the bottom right, select Show Package Details. Select the following additional options under Android 6.0 (Marshmallow):

  • Google APIs
  • Android SDK Platform 23
  • Sources for Android 23
  • Intel x86 Atom System Image
  • Intel x86 Atom64 System Image
  • Google APIs Intel x86 Atom System Image
  • Google APIs Intel x86 Atom64 System Image

Go to SDK Tools tab and select Show Package Details. Under Android SDK Build-Tools, select version 23.01.

Click Apply, confirm the change to install, accept the license agreements, then click Finish. You can now close android studio.

Add the following lines to ~/.bashrc.

export ANDROID_HOME=~/Android/Sdk
export PATH=${PATH}:${ANDROID_HOME}/tools:${ANDROID_HOME}/platform-tools

Source your .bashrc file.

source ~/.bashrc

Step 10: Install Virtualbox

sudo apt-get install -y virtualbox

Step 11: Install Genymotion

Go here and create a Genymotion account. Sign in, click the Download link in the top banner, and then click the Download for Ubuntu (64bit) button.

Make the file executable. Note, your version may vary.

chmod +x genymotion-2.8.0-linux_x64.bin

Run the file.


When prompted, type y to install to the current directory or n to install somewhere else.

cd into the genymotion directory that was created, and start up genymotion.

cd genymotion

You will be prompted to create your first virtual device, click yes. Next, click the Sign In link at the bottom right.

After signing in, select Samsung Galaxy S6 - 6.0.0 - API 23 - 1440x2560 and create the virtual device. Click Finish.

You should return to a list of your devices.

Go to Settings, click on the ADB tab. Select 'Use custom Android SDK tools' and enter the path of your Android SDK, which should be something like /home/<username>/Android/Sdk.

Step 12: Create and run your first app

Create an app from the re-natal template.

re-natal init FutureApp
cd future-app

Start Genymotion (if it isn't already running)


Start a simulated android device

In Genymotion, select the device you made earlier and hit Start.

Prepare the app

In another terminal:

re-natal use-android-device genymotion
re-natal use-figwheel

Start figwheel

lein figwheel android

Start react-native

In another terminal:

react-native start

Run the app

In yet another terminal:

react-native run-android

Verify the figwheel REPL is connected to the simulated app

In the figwheel REPL type:

(js/alert "Hello, world!")

You should see an alert pop-up in the simulated app.

Verify that you can debug remotely in a browser

In the simulated app, press Ctrl + M. Select enable debug remotely, which should take you to localhost:8081/debugger-ui. Once there press Ctrl + Shift + J, this should open the developer's console. In the figwheel REPL, type:

(js/console.log "Hello, console!")

You should see the message printed to the developer's console.
