There might have been confusion around App Sim. App Simulator does not support simulating Standard Android Applications. If you are building a 2D android Application, you can use the Android Emulator inside Android Studio Instead. Additionally App Simulator and MLSDK have been deprecated and we recommend using the more recent OpenXR APIs.

Thank you for reply
My application is combination of 2D and 3D. 2D screens developed by Android and 3D screens developed by Unity. I have 2D login(native Android) and once login rendering HTML pages(Rendering webpages in I Frame) with fetching data from Android SQLite database.
then invoke 3D Content(Unity) from Android..
Folder structure created by Android.
I want to know magic leap supported all Android native API's(Camera, Microphone, Video, Audio) or not
Now I want to test in Magic Leap device. As of now i don't have physical device, need to test in simulator.
I am new to magic leap development. Can you help me.

Understood, Magic Leap 2 supports Android's APIs. The OS is based on Android 10. There are some small differences between standard Android but those are on the Rendering side rather than Multimedia since the Magic Leap displays content for both the left, and right eyes.

That said, based on your description the APIs will work as expected on the physical device.
