<android.support.constraint.ConstraintLayout
   xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: app = "http://schemas.android.com/apk/res-auto"

      app :layout_constraintTop_toTopOf= "parent" />
</android.support.constraint.ConstraintLayout>

Step 3 − Add the following code to src/MainActivity.java

package app.tutorialspoint.com.notifyme;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
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 {
   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) {
            Intent intent = new Intent(getApplicationContext(), MainActivity. class );
            final PendingIntent resultPendingIntent =
            PendingIntent. getActivity (
               MainActivity. this,
               0,
               intent,
               PendingIntent. FLAG_CANCEL_CURRENT
            );
            NotificationCompat.Builder mBuilder =
               new NotificationCompat.Builder(MainActivity. this,
               default_notification_channel_id )
               .setSmallIcon(R.drawable. ic_launcher_foreground )
               .setContentTitle( "Test" )
               .addAction(R.drawable. ic_launcher_foreground, "Add", resultPendingIntent)
               .setContentIntent(resultPendingIntent)
               .setStyle( new NotificationCompat.BigTextStyle().bigText( "Big View Styles" ))
               .setContentText( "Hello! This is my first push notification" );
            NotificationManager mNotificationManager = (NotificationManager)
               getSystemService(Context. NOTIFICATION_SERVICE );
            mNotificationManager.notify(( int ) System. currentTimeMillis (), mBuilder.build()) ;
         }
      });
   }
}

Step 4 − 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" >
   <uses-permission android :name= "android.permission.VIBRATE" />
   <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>
      <service
         android :name= ".MyFirebaseMessagingService"
         android :exported= "false" >
         <intent-filter>
            <action android :name= "com.google.firebase.MESSAGING_EVENT" />

      </service>
   </application>
</manifest>
