I have a problem with push notifications on android java - android

Hey I am just learning to Android development so I am trying to make push notifications. Book I read says to build it like that. But android studio says "Builder is deprecated" about NotificationCompat.Builder(this)
I also tried to find information on the internet, but none of it works.
This is my code:
package com.example.notifications;
import androidx.appcompat.app.AppCompatActivity;
import androidx.core.app.NotificationCompat;
import androidx.core.app.TaskStackBuilder;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
public class MainActivity extends AppCompatActivity {
public static final int NOTIFICATION_ID = 1;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void onClick(View view){
NotificationCompat.Builder mBuilder =
(NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setContentText("bioba")
.setContentTitle("aboba");
Intent resultIntent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}
}
I use emulator of Android 8.1

Use public Builder(#NonNull Context context, #NonNull String channelId) instead, where channelId is the NotificationChannel where the constructed Notification will be posted.

AlarmManager + NotificationManager not working

First of all I would like to thank you for clicking on this thread.
Thank you so much for taking your time to read this.
I was planning for the application push a notification on a specific time.
I followed some tutorials online but it seems it doesn't work.
There is no error message on the code itself but no notification is coming out.
Here's my "Notification_receiver.java" file:
package com.example.reviewerapplication;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Build;
import androidx.annotation.RequiresApi;
import androidx.core.app.NotificationCompat;
public class Notification_receiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
Intent repeating_intent = new Intent(context,Chapterchoice.class);
String daily10 = "daily";
intent.putExtra("daily",daily10);
repeating_intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(context,100,repeating_intent,PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder builder = new NotificationCompat.Builder(context)
.setContentIntent(pendingIntent)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("Sample Title")
.setContentText("same message")
.setAutoCancel(true);
if (intent.getAction().equals("MY_NOTIFICATION_MESSAGE")) {
notificationManager.notify(100, builder.build());
}
}
}
This is what is on my MainActivity:
//Daily Notification
val calendar = Calendar.getInstance()
calendar.set(Calendar.HOUR_OF_DAY,21)
calendar.set(Calendar.MINUTE,53)
calendar.set(Calendar.SECOND,0)
val intent2 = Intent(this, Notification_receiver::class.java)
intent2.setAction("MY_NOTIFICATION_MESSAGE")
var pendingIntent = PendingIntent.getBroadcast(this,100,intent2,PendingIntent.FLAG_UPDATE_CURRENT )
var alarmManager = getSystemService(Context.ALARM_SERVICE) as AlarmManager
alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,calendar.timeInMillis,AlarmManager.INTERVAL_DAY,pendingIntent)
I actually got it fixed just now.
my issue is that I used "activity" in the Manifest instead of using "receiver"

Android , create notification code doing nothing

Unable to create notification, I have checked several articles code samples look same as mine. Please check the below code and where I am doing the mistake.
Below I have pasted 2 classes. MainActivity class, where one button click should create notification. Second class, where notification is created.
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
NotificationBuilder nB=new NotificationBuilder();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
goToSecondActivity();
nB.createNotify();
}
});
}
private void goToSecondActivity() {
Intent intent = new Intent(this, SecondActivity.class);
startActivity(intent);
}
}
**Second class**
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.v4.app.TaskStackBuilder;
import android.support.v7.app.AppCompatActivity;
public class NotificationBuilder extends AppCompatActivity {
void createNotify() {
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.ic_launcher)
.setContentTitle("My notification")
.setContentText("Hello World!");
Intent resultIntent = new Intent(this, MainActivity.class);
TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
stackBuilder.addParentStack(MainActivity.class);
stackBuilder.addNextIntent(resultIntent);
PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(
0, PendingIntent.FLAG_UPDATE_CURRENT);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
mNotificationManager.notify(001, mBuilder.build());
}
}
Tried with noughat and Kitkat Apis level.
Tried using another phone, but similar results
NotificationBuilder nB=new NotificationBuilder();
You're essentially never supposed to create an Activity like this. It means several required internal components will not be properly initialized.
This means that all the instances of this in createNotify do not work as expected. The context needs to be MainActivity and not your builder class.
Stop extending NotificationBuilder to an Activity and pass the correct Context as a parameter to createNotify. Replacing most calls of this with the context should fix your code.

Notification sound is not created when phone is locked

I'm developing a chat application and I am using Firebase Cloud Messaging. Notification works properly. When the phone is locked, the notification is received properly, but the sound is not generated.
Any help is appreciated.

Go to FCM CONSOLE and enable sound and define key 'sound'==>'default';
and go to php cansole and and type Following code 'sound'==>'default'; thats work properly

Android notification from service does not open activity

Updated MyService #CommonsWare
i have a service that if started will set up an alarm that triggers the notification.
This works fine and the alarms are canceled if the service is stopped.
i am trying to get the notification to open a new activity class but can not get it done
my service class is the following:
package com.example.andtip;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.support.v4.app.NotificationCompat;
public class BReceiver extends BroadcastReceiver {
private static final int MY_NOTIFICATION_ID=1;
NotificationManager notificationManager;
Notification myNotification;
public void onReceive(Context context, Intent intent) {
Intent myIntent = new Intent(context, DoSomething.class);
PendingIntent pi = PendingIntent.getBroadcast(context, 0, new Intent("com.example.andtip"),0 );
PendingIntent pi2 = PendingIntent.getActivity(context, 0, myIntent,0 );
myNotification=new NotificationCompat.Builder(context)
.setContentTitle("This is a notification from the example alarm application.")
.setContentText("Notification")
.setTicker("Notification!")
.setWhen(System.currentTimeMillis())
.setContentIntent(pi)
.setDefaults(Notification.DEFAULT_SOUND)
.setAutoCancel(true)
.setSmallIcon(R.drawable.ic_launcher)
.build();
notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(MY_NOTIFICATION_ID, myNotification);
}
}
how should i link the intent pi2 to the notification?
i am trying to get the notification to open a new activity class but can not get it done
You are using getBroadcast() to create your PendingIntent. Use getActivity() to create a PendingIntent that starts up an activity. Make sure that the Intent you put in the PendingIntent is for an activity, and make sure that the activity has its entry in the manifest.

Why my notification doesn't work?

I put here my code...
I explain my problem..
when I create a notification, it appears to me immediately even if I enter a specific time to make it appear.
at that time instead opens automatically as if i push on notification.
can you tell me how I can play it at the time that i inserted?
thanks

Intent intent =new Intent(context, NotificationReceiverActivity.class);
intent.putExtra("dati", dati);
intent.setData(Uri.parse("content://"+date));
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);

.setTicker(title)
.setDefaults(Notification.DEFAULT_LIGHTS| Notification.DEFAULT_VIBRATE| Notification.DEFAULT_SOUND)
.setContentIntent(pendingIntent);
Notification notification=notificationBuilder.build();
alarmManager.set(AlarmManager.RTC_WAKEUP,
myAlarmDate.getTimeInMillis(), pendingIntent);
notificationManager.notify((int) myAlarmDate.getTimeInMillis(), notification);
}
}
The method NotificationManager.notify(int id, Notification notification) posts the notification immediately. The first argument is an id you specify and not the time the notification should be displayed.
You could use the AlarmManager to schedule a notification.
