Create and Manage Notification Channels in Android

This example demonstrate about Create and Manage Notification Channels in Android

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<? xml version= "1.0" encoding= "utf-8" ?> <android.support.constraint.ConstraintLayout    xmlns: android = "http://schemas.android.com/apk/res/android"    xmlns: app = "http://schemas.android.com/apk/res-auto"    xmlns: tools = "http://schemas.android.com/tools"    android :layout_width = "match_parent"    android :layout_height = "match_parent"    android :padding = "16dp"    tools :context = ".MainActivity" >    <Button       android :id = "@+id/btnCreateNotification"       android :layout_width = "0dp"       android :layout_height = "wrap_content"       android :text = "Create notification"       app :layout_constraintBottom_toBottomOf = "parent"       app :layout_constraintEnd_toEndOf = "parent"       app :layout_constraintStart_toStartOf = "parent"       app :layout_constraintTop_toTopOf = "parent" /> </android.support.constraint.ConstraintLayout>

Step 3 − Add a sound into raw folder

Step 4 − Add the following code to src/MainActivity.java

package app.tutorialspoint.com.notifyme ; import android.app.NotificationChannel ; import android.app.NotificationManager ; import android.content.ContentResolver ; import android.content.Context ; import android.graphics.Color ; import android.media.AudioAttributes ; import android.net.Uri ; import android.support.v4.app.NotificationCompat ; import android.support.v7.app.AppCompatActivity ; import android.os.Bundle ; import android.view.View ; import android.widget.Button ; public class MainActivity extends AppCompatActivity {    public static final String NOTIFICATION_CHANNEL_ID = "10001" ;    private final static String default_notification_channel_id = "default" ;    @Override    protected void onCreate (Bundle savedInstanceState) {       super .onCreate(savedInstanceState) ;       setContentView(R.layout. activity_main ) ;       Button btnCreateNotification = findViewById(R.id. btnCreateNotification ) ;       btnCreateNotification.setOnClickListener( new View.OnClickListener() {          @Override          public void onClick (View v) {             Uri sound = Uri. parse (ContentResolver. SCHEME_ANDROID_RESOURCE + "://" + getPackageName() + "/raw/quite_impressed.mp3" ) ;             NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(MainActivity. this,                default_notification_channel_id )                .setSmallIcon(R.drawable. ic_launcher_foreground )                .setContentTitle( "Test" )                .setSound(sound)                .setContentText( "Hello! This is my first push notification" );             NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context. NOTIFICATION_SERVICE ) ;             if (android.os.Build.VERSION. SDK_INT >= android.os.Build.VERSION_CODES. O ) {                AudioAttributes audioAttributes = new AudioAttributes.Builder()                   .setContentType(AudioAttributes. CONTENT_TYPE_SONIFICATION )                   .setUsage(AudioAttributes. USAGE_ALARM )                   .build() ;                int importance = NotificationManager. IMPORTANCE_HIGH ;                NotificationChannel notificationChannel = new                   NotificationChannel( NOTIFICATION_CHANNEL_ID , "NOTIFICATION_CHANNEL_NAME" , importance) ;                notificationChannel.enableLights( true ) ;                notificationChannel.setLightColor(Color. RED ) ;                notificationChannel.enableVibration( true ) ;                notificationChannel.setVibrationPattern( new long []{ 100 , 200 , 300 , 400 , 500 , 400 , 300 , 200 , 400 }) ;                notificationChannel.setSound(sound , audioAttributes) ;                mBuilder.setChannelId( NOTIFICATION_CHANNEL_ID ) ;                assert mNotificationManager != null;                mNotificationManager.createNotificationChannel(notificationChannel) ;             }             assert mNotificationManager != null;             mNotificationManager.notify(( int ) System. currentTimeMillis (), mBuilder.build()) ;          }       }) ;    } }

Step 5 − Add the following code to androidManifest.xml

<? xml version = "1.0" encoding = "utf-8" ?> <manifest xmlns: android = "http://schemas.android.com/apk/res/android"    package = "app.tutorialspoint.com.notifyme" >    <application       android :allowBackup = "true"       android :icon = "@mipmap/ic_launcher"       android :label = "@string/app_name"       android :roundIcon = "@mipmap/ic_launcher_round"       android :supportsRtl = "true"       android :theme = "@style/AppTheme" >       <activity android :name = ".MainActivity" >          <intent-filter>             <action android :name = "android.intent.action.MAIN" />             <category android :name = "android.intent.category.LAUNCHER" />          </intent-filter>       </activity>    </application> </manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen −
