61.3 Creating the Notification Channel

As with the example in the previous chapter, a channel must be created before a notification can be sent. Edit the MainActivity.java file and add code to create a new channel as follows:

.

.

import android.app.NotificationChannel;

import android.app.NotificationManager;

import android.content.Context;

import android.graphics.Color;

.

.

public class MainActivity extends AppCompatActivity {

 

    NotificationManager notificationManager;

    private String channelID = "com.ebookfrenzy.directreply.news";

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_direct_reply);
