Runtime Notification Permission in Android 13 in JAVA & KOTLIN

Earlier Android version we just need permission in Android Manifest file. But onwards Android 13 also need runtime permission. If user Allowed it then it will receive notifications otherwise it will not work. So, here is what we need to enable it and ask for permission.

First of all we will mention permission in Manifest file.

    <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/>Code language: HTML, XML (xml)

Then we will add given below snippet it in code file.
For JAVA

private void requestNotificationPermission() {

        ActivityResultLauncher<String> requestPermissionLauncher = registerForActivityResult(
                new ActivityResultContracts.RequestPermission(),
                isGranted -> {
                    if (isGranted) {
                        Log.d("DEBUG_TAG", "Notifications permission granted");
                    } else {
                        Snackbar.make(
                                mainLayout,
                                String.format(
                                        "Notifications permission denied",
                                        getString(R.string.app_name)
                                ),
                                Snackbar.LENGTH_INDEFINITE
                        ).setAction("Go to Settings", v -> {
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                                Intent settingsIntent = new Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS)
                                        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
                                        .putExtra(Settings.EXTRA_APP_PACKAGE, getPackageName());
                                startActivity(settingsIntent);
                            }
                        }).show();
                    }
                }
        );
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
            requestPermissionLauncher.launch(Manifest.permission.POST_NOTIFICATIONS);
        }
    }Code language: JavaScript (javascript)

For Kotlin

private fun requestNotificationPermission() {
    val requestPermissionLauncher = registerForActivityResult(
        ActivityResultContracts.RequestPermission()
    ) { isGranted ->
        if (isGranted) {
            Log.d("DEBUG_TAG", "Notifications permission granted")
        } else {
            Snackbar.make(
                mainLayout,
                "Notifications permission denied",
                Snackbar.LENGTH_INDEFINITE
            ).setAction("Go to Settings") {
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
                    val settingsIntent = Intent(Settings.ACTION_APP_NOTIFICATION_SETTINGS)
                        .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
                        .putExtra(Settings.EXTRA_APP_PACKAGE, packageName)
                    startActivity(settingsIntent)
                }
            }.show()
        }
    }
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        requestPermissionLauncher.launch(Manifest.permission.POST_NOTIFICATIONS)
    }
}
