Godot 3.3 Android Development Setup

Set up Godot 3.3 for making games on android.

Open the relevant documentation

Configuring your android device for godot:

First enable developer mode on your phone. Tap the build number 3-5 times Settings > System > About phone > build number

Then enable use debugging. Settings > System > Advanced > Developer options > Debugging > USB debugging

Installing stuff

Install Android Development Studio

On linux, download and extract Android Development Studio. Open the install instructions file and follow its guidelines.

Run the bin/start.sh file and click through the various menus.

Then open apk manager under configure > SDK Manager. Enable the latest android sdk version and the sdk for the version of android on your cellphone.

Now add the Sdk Path to Godots editor settings. Editor Settings > Export > Android > Android Sdk Path

Installing Open Jdk.

Install open jdk on your system. In my case I just run:

1

sudo apt install openjdk-8-jdk

Configuring Godot

Create debug keys

Create a debug.keystore file with:

1

keytool -keyalg RSA -genkeypair -alias androiddebugkey -keypass android -keystore debug.keystore -storepass android -dname "CN=Android Debug,O=Android,C=US" -validity 9999 -deststoretype pkcs12

Again in your editor settings, Add the path to the debug.keystore file to the Debug Keystore field. Then copy the -keypass variable "android" to the Debug Keystore Pass field and copy the -alias variable "androiddebugkey" to the Debug Keystore User field

Configure Exports

Download and Install the default export template under Editor > Manage Export Templates.

In your Project > Export... settings, add the Android preset.

My projects tend to use json files. So I need to add *.json as a resource type to include in the export.

Make sure runnable is enabled and then click export.

One click install

Now plugin in your phone to your computer via usb. you should see a Android icon appear in the godot editor.

If it doesn’t show up, Check to see if you can transfer files to your phone. Occasionally my phone will fail to connect to my computer at all. Rebooting my cellphone normally resolves this.

If you can transfer files then make sure usb debugging is enabled in the developer options.

Also make sure your android export has runnable enabled.

If its still not working then double check your editor configuration.

Once you have the android button available, press it to test your game on your phone.

Project Window Settings

Before you get to far into your project Its worth considering your display settings.

I like set my Stretch > Mode to viewport and Stretch > Aspect to expand.

You can read more about these setting in Godot’s Multiple Resolutions Docs

I am using a square 600x600 resolution because I want my design to expand to either screen orientation.

Making a icon

First read about providing launcher icons for godot also read about designing adaptive icons for Android

In the android export settings you will find 3 fields for launcher icons:
