Code Review

This pull request introduces comprehensive notification snippets, including channel creation, basic and styled notifications, tap actions, and reply handling with a dedicated ReplyReceiver. Feedback focuses on addressing a potential resource leak by properly closing an InputStream in ReplyReceiver, improving type safety when accessing the NotificationManager, and using shared constants for notification reply keys to ensure consistency.

[gemini-code-assist]

The InputStream obtained from openInputStream is not closed, which can lead to resource leaks. Use the .use extension function to ensure the stream is closed automatically even if an exception occurs during processing.

                context.contentResolver.openInputStream(imageUri)?.use { inputStream ->
                    val bitmap = BitmapFactory.decodeStream(inputStream)
                    // Display the image
                    // ...
                }

[gemini-code-assist]

For better type safety and consistency with modern Android practices, use context.getSystemService(NotificationManager::class.java). This avoids manual casting and is safer when the SDK version is 23 or higher.

Suggested change

	val notificationManager: NotificationManager =
	context.getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
	notificationManager.createNotificationChannel(channel)
	val notificationManager = context.getSystemService(NotificationManager::class.java)
	notificationManager?.createNotificationChannel(channel)

[gemini-code-assist]

It is recommended to use the constant ReplyReceiver.KEY_TEXT_REPLY instead of a hardcoded string. This ensures that the key used to send the reply matches the key used to retrieve it in the receiver.

Suggested change

	val KEY_TEXT_REPLY = "key_text_reply"
	val KEY_TEXT_REPLY = ReplyReceiver.KEY_TEXT_REPLY
