Launch fail on my android device

Been trying to launch my game on my android mobile device (android 6) but every time I try to launch the game I get this error…

LogPlayLevel: ERROR: Can’t make an APK without SDK API ‘android-23’ minimum installed
LogPlayLevel: (see C:\Users\Grey\AppData\Roaming\Unreal Engine\AutomationTool\Logs\C+Program+Files+Epic+Games+UE_4.19\UAT_Log.txt for full exception trace)
LogPlayLevel: AutomationTool exiting with ExitCode=1 (Error_Unknown)
LogPlayLevel: Completed Launch On Stage: Deploy Task, Time: 9.256770
PackagingResults: Error: Launch failed! Unknown Error
LogSlate: Took 0.000251 seconds to synchronously load lazily loaded font ‘…/…/…/Engine/Content/Slate/Fonts/DroidSansMono.ttf’ (77K)

I have no idea how to fix this
