Try following the setup guide for android SDK and NDK here [Link](https://docs.unrealengine.com/4.26/en-US/SharingAndReleasing/Mobile/Android/Setup/AndroidStudio/). Look at the section “Android SDK and NDK Compatibility” for the required android studio version and NDK. After setup, use one of the mobile template to build to device for testing. ---
