Trusted UI (Trusted Execution Environment or TEE) Implementation

I am trying to implement the PIN entry page using device’s TEE. I have acquired the confidential OEM Documentation. It have some C++ code and some code flow such as creating a TUI Session, start it, do some input processing, then stop and finally terminate it. I have no clue where to put that code.

I am completely new to android (or even to the software dev field), I am completely struct how to continue. Anybody please help me with it, and if there any good resources, please provide.

Implementing a PIN entry page using the device’s TEE involves managing a Trusted User Interface (TUI) session, following steps like session creation, input processing, and termination. Since the provided OEM documentation contains C++ code, it likely needs integration via JNI in an Android app. As a beginner, start by understanding Android NDK and TEE basics. Refer to Android NDK docs, GlobalPlatform TEE specs, and any OEM-provided SDKs. If unclear, reaching out to the OEM or Android developer forums can provide further guidance.
