The UI will ask you which app you want to sign, and your dummy app should be pre-selected. The instructions to create such a keystore file are available on the Android Developers documentation.īasically, just create a dummy Android project with Android Studio, and then go to Build > Generate Signed Bundle / APK.

Let us go through an example of how to create your application file without resorting to Expo servers. It is open-source and available on GitHub. The build process relies on a CLI tool called turtle-cli. Luckily for you, Expo provide the tools they are using on their servers for free (did I mention they’re great!?). (Although, if you made the same mistake as I did, a ticket to their support can delete any files you had wished to keep private. And you obtain a nice URL to the artifact created for you when the build finishes.īut, again, this is public.
