Run the auto installer for unreal android sdk¶

In order to facilitate the setup for Unreal-Android usage we added to the prepare_repo.sh a optional parameter that is --install-mobile-sdk.

Warning

You will need to run as a adminitrator in order to run all the processes required to install.

Note

The --install-mobile-sdk basically gets the version of your UProject and run the Turnkey command from unreal to install everything.

Please follow the extra steps in the unreal documentation to have everything ready.

Installing the Turnkey¶

The Turnkey will start to install all needed, for most cases you will need only the default. But bellow you can see as the default of the options should looks like.
