Prerequisites

Create a new project in Android Studio and ensure the native development environment (NDK) is properly conifgured.

Loading the Native Library

Load the required native driver library in your main activity class:

static {
    System.loadLibrary("native_driver");
}

Setting Up the Hardware Interface

Define a helper class to manage the native methods and initialize the connection:

public class HardwareInterface {
    public native void setupDevice();
    public native int executeCommand();
}

Invoking Driver Operations

Initialize the hardware interface and trigger a specific operation within the activity lifecycle:

import android.os.Bundle;
import android.util.Log;
import androidx.appcompat.app.AppCompatActivity;

public class DeviceActivity extends AppCompatActivity {
    private HardwareInterface hwInterface;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_device);

        hwInterface = new HardwareInterface();
        
        // Initialize the hardware connection
        hwInterface.setupDevice();
        
        // Execute a driver command
        int status = hwInterface.executeCommand();
        
        // Check the execution result
        if (status == 0) {
            Log.i("Hardware", "Operation completed successfully");
        } else {
            Log.e("Hardware", "Error during driver execution");
        }
    }
}
