How to integrate Runtime permissions with other Android components?

Integrating runtime permissions with other Android components is essential for modern application development. Below, we outline a straightforward method to implement runtime permissions, using an example of accessing the device's camera.

Runtime Permissions in Android

Starting from Android 6.0 (API level 23), users are prompted to grant or deny permissions at runtime instead of at install time. This change enhances user control over their data and privacy.

Example: Accessing the Camera

Here's how you can integrate runtime permissions to access the camera in an Android application.

// In your Activity or Fragment private static final int REQUEST_CAMERA_PERMISSION = 200; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); // Check for camera permission if (ContextCompat.checkSelfPermission(this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) { // Request the permission ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.CAMERA}, REQUEST_CAMERA_PERMISSION); } else { // Permission granted, proceed with camera functionality openCamera(); } } @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) { super.onRequestPermissionsResult(requestCode, permissions, grantResults); if (requestCode == REQUEST_CAMERA_PERMISSION) { // If request is cancelled, the result arrays are empty. if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { // Permission granted, open camera openCamera(); } else { // Permission denied, show a message to the user Toast.makeText(this, "Camera permission is required.", Toast.LENGTH_SHORT).show(); } } } private void openCamera() { // Your code to open the camera }
