    Answer it

    I wanna create a library for sending a notification to my android app but i don't know how it works and what kind of data I should give to the function in the class. this is my code for sending a notification but I don't know how to put it in the class for using in another section of the app.

     

    This code works in MainActivity

     

    Intent intent = new Intent(context, MainActivity.class);
                    PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);
    
                    NotificationCompat.Builder b = new NotificationCompat.Builder(context);
    
                    b.setAutoCancel(true)
                            .setDefaults(Notification.DEFAULT_ALL)
                            .setWhen(System.currentTimeMillis())
                            .setSmallIcon(R.drawable.ic_launcher_background)
                            .setTicker("Hearty365")
                            .setContentTitle("Default notification")
                            .setContentText("Lorem ipsum dolor sit amet, consectetur adipiscing elit.")
                            .setDefaults(Notification.DEFAULT_LIGHTS | Notification.DEFAULT_SOUND)
                            .setContentIntent(contentIntent)
                            .setContentInfo("Info");
    
    
                    NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
                    notificationManager.notify(1, b.build());

  • You can use and NotificationCompact builder to create notification for your android application. If you want to show Firebase push notification you can follow this post: https://trinitytuts.com/firebase-push-notification-android/
    NotificationCompat.Builder builder = null;
    final int NOTIFY_ID = 0; // ID of notification
    String id = "mychannel"; // default_channel_id
    
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
            PendingIntent.FLAG_ONE_SHOT);
    
    Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
    
    if (notifManager == null) {
        notifManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    }
    
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        int importance = NotificationManager.IMPORTANCE_HIGH;
        NotificationChannel mChannel = notifManager.getNotificationChannel(id);
        if (mChannel == null) {
            mChannel = new NotificationChannel(id, title, importance);
            mChannel.enableVibration(true);
            mChannel.setVibrationPattern(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400});
            notifManager.createNotificationChannel(mChannel);
        }
        builder = new NotificationCompat.Builder(context, id)
                .setContentTitle(title)
                .setContentText(desciption)
                .setContentIntent(pendingIntent)
                .setSound(defaultSoundUri)
                .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                .setSmallIcon(R.mipmap.ic_launcher)
                .setPriority(NotificationCompat.PRIORITY_DEFAULT);
    } else {
        builder = new NotificationCompat.Builder(context, id);
        intent = new Intent(context, MainActivity.class);
        intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        builder.setContentTitle(title)
                .setContentText(desciption)                            // required
                .setSmallIcon(android.R.drawable.ic_popup_reminder)   // required
                .setDefaults(Notification.DEFAULT_ALL)
                .setAutoCancel(true)
                .setContentIntent(pendingIntent)
                .setTicker("Accept your request")
                .setVibrate(new long[]{100, 200, 300, 400, 500, 400, 300, 200, 400})
                .setPriority(Notification.PRIORITY_HIGH);
    }
    Notification notification = builder.build();
    NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
    notificationManager.notify(NOTIFY_ID, notification);
  • public class MainActivity extends ActionBarActivity {
       EditText ed1,ed2,ed3;
       protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          setContentView(R.layout.activity_main);
    
          ed1=(EditText)findViewById(R.id.editText);
          ed2=(EditText)findViewById(R.id.editText2);
          ed3=(EditText)findViewById(R.id.editText3);
          Button b1=(Button)findViewById(R.id.button);
    
          b1.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                String tittle=ed1.getText().toString().trim();
                String subject=ed2.getText().toString().trim();
                String body=ed3.getText().toString().trim();
    
                NotificationManager notif=(NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
                Notification notify=new Notification.Builder
                   (getApplicationContext()).setContentTitle(tittle).setContentText(body).
                   setContentTitle(subject).setSmallIcon(R.drawable.abc).build();
                    
                   notify.flags |= Notification.FLAG_AUTO_CANCEL;
                   notif.notify(0, notify);
             }
          });
       }
    }
    Android provides NotificationManager class for this purpose. In order to use this class, you need to instantiate an object of this class by requesting the android system through getSystemService() method.
