One-click deploy is a feature that is available once a platform is properly configured and a supported device is connected to the computer. Since things can go wrong at many levels (platform may not be configured correctly, SDK may be incorrectly installed, device may be improperly configured, etc.), it's good to let the user know that it exists.
After adding an Android export preset marked as Runnable, Godot can detect when a USB device is connected to the computer and offer the user to automatically export, install and run the project (in debug mode) on the device. This feature is called one-click deploy.
One-click deploy is only available once you've added an export template marked as Runnable in the Export dialog. You can mark several export presets as runnable, but only one preset per platform may be marked as runnable. If you mark a second preset in a given platform as runnable, the other preset will no longer be marked as runnable.
Android: Exports the project with debugging enabled and runs it on the connected device.
Make sure to follow the steps described in Android用にエクスポート. Otherwise, the one-click deploy button won't appear.
If you have more than one device connected, Godot will ask you which device the project should be exported to.
HTML5: Starts a local web server and runs the exported project by opening the default web browser.
Support for more platforms such as iOS is planned.
Using one-click deploy¶
If deploying to Android, enable developer mode on your mobile device then enable USB debugging in the device's settings.
After enabling USB debugging, connect the device to your PC using an USB cable.
For advanced users, it should also be possible to use wireless ADB.
Make sure there is an export preset marked as Runnable for the target platform (Android or HTML5).
If everything is configured correctly and with no errors, platform-specific icons will appear in the top-right corner of the editor.
Click the button to export to the desired platform in one click.
