java.lang.ClassCastException: com.example.BellasHBG.LocationService cannot be cast to com.google.android.gms.location.LocationListener

I'm getting
java.lang.ClassCastException: com.example.BellasHBG.LocationService cannot be cast to com.google.android.gms.location.LocationListener
but I don't know how to resolve. Removing keyword abstract does not fix the problem. This is new to me, and I'm not that knowledgeable of java so any help is appreciated. The error seems top be occurring in LocationService on the following line: LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mlocationRequest, (com.google.android.gms.location.LocationListener) this);
The intent is to get location updates and send a notification to the app user if the location sells this particular bakery product.

How to change firebase databse by connectivity status from background?

I tried to change database onDisconnect method.
I want to change the database when connectivity available from background.
For example,
Suppose currently i am in MainActivity and status is Online and in onPause and onDestroy it becomes offline. For my side it is not enough to set online/offline status.
For this i want
if i have connectivity (background and foreground) my status
is online
if i lost connectivity in the BACKGROUND, my status is offline. And whenever connectivity is available and app is in killed Mode, my status is online.
For this solution stackoverflow suggests me to use BroadCastReceiver, but i dont know how to use this class

We can easily do it by using a Service and a Broadcast Receiver simultaneously to get the output as you wish. This will work always i.e when app is running, app is minimized or when app is even removed from minimized apps.
1.Manifest Code :
<application
...
<service android:name=".MyService" />
</application>
2.MyService.java
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.os.IBinder;
import android.support.annotation.Nullable;
import android.support.v4.app.NotificationCompat;
import android.util.Log;
import android.widget.Toast;
public class MyService extends Service {
static final String CONNECTIVITY_CHANGE_ACTION = "android.net.conn.CONNECTIVITY_CHANGE";
NotificationManager manager ;
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
// Let it continue running until it is stopped.
Toast.makeText(this, "Service Started", Toast.LENGTH_LONG).show();
IntentFilter filter = new IntentFilter();
filter.addAction("android.net.conn.CONNECTIVITY_CHANGE");
BroadcastReceiver receiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (CONNECTIVITY_CHANGE_ACTION.equals(action)) {
//check internet connection
if (!ConnectionHelper.isConnectedOrConnecting(context)) {
if (context != null) {
boolean show = false;
if (ConnectionHelper.lastNoConnectionTs == -1) {//first time
show = true;
ConnectionHelper.lastNoConnectionTs = System.currentTimeMillis();
} else {
if (System.currentTimeMillis() - ConnectionHelper.lastNoConnectionTs > 1000) {
show = true;
ConnectionHelper.lastNoConnectionTs = System.currentTimeMillis();
}
}
if (show && ConnectionHelper.isOnline) {
ConnectionHelper.isOnline = false;
Log.i("NETWORK123","Connection lost");
//manager.cancelAll();
}
}
} else {
Log.i("NETWORK123","Connected");
showNotifications("APP" , "It is working");
// Perform your actions here
ConnectionHelper.isOnline = true;
}
}
}
};
registerReceiver(receiver,filter);
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service Destroyed", Toast.LENGTH_LONG).show();
}
}
3.ConnectionHelper.java
import android.content.Context;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
public class ConnectionHelper {
public static long lastNoConnectionTs = -1;
public static boolean isOnline = true;
public static boolean isConnected(Context context) {
ConnectivityManager cm =(ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return activeNetwork != null && activeNetwork.isConnected();
}
public static boolean isConnectedOrConnecting(Context context) {
ConnectivityManager cm =(ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
return activeNetwork != null &&
activeNetwork.isConnectedOrConnecting();
}
}
4.Your Activity Code
startService(new Intent(getBaseContext(), MyService.class));
With this code, you will be able to check the connectivity when the app is onStart, On pause and even when the app is destroyed

You can use this method. It works fine for me.
DatabaseReference connectedRef = FirebaseDatabase.getInstance().getReference(".info/connected");
connectedRef.addValueEventListener(new ValueEventListener() {
#Override
public void onDataChange(#NonNull DataSnapshot snapshot) {
boolean connected = snapshot.getValue(Boolean.class);
if (connected) {
Log.d("FirasChebbah", "connected");
} else {
Log.d("FirasChebbah", "not connected");
}
}
#Override
public void onCancelled(#NonNull DatabaseError error) {
Log.w("FirasChebbah", "Listener was cancelled");
}
});

How to make an android app show notification even when it is closed

I want to make an app that shows a notification as soon as headphone is plugged in and remove it when it is plugged out.

// boolean connectedMicrophone = (intent.getIntExtra("microphone", 0) == 1) && connectedHeadphones;
String headsetName = intent.getStringExtra("name");
Log.v("message", "headphone connected" + headsetName);
Intent i = new Intent(context, MainActivity.class);

Using IntentService instead of AsyncTask for Broadcast Receiver?

I am in the process of trying to get an email sent using BroadcastReceiver, the code is working correct using AsyncTask when using onClick but does not work when AlarmReceiver is being called.
Would it be better to use IntentService for this method? If so, what is the best way to write this?
Can anyone help with this problem? I am still new to java and want to help improve my knowledge. :)
Any help would be appreciated! Thank you!

import android.os.AsyncTask;
import android.util.Log;
import android.widget.Toast;
import static android.graphics.Color.GREEN;
public class AlarmReceiver extends BroadcastReceiver {
Context cxt;
Activity context;
#Override
public void onReceive(Context arg0, Intent arg1) {

addNotification();
new SendMail().execute();
}
private class SendMail extends AsyncTask<String, Integer, Void> {

String[] toArr = {"toemail#outlook.com"};
m.setTo(toArr);
m.setFrom("fromemail#gmail.com");
m.setSubject("Achieve Alert!");
m.setBody("This is a reminder about your upcoming assignment or examination!");
try {

First start Intent service from Alarm manager :
private void setAlarm(Calendar targetCal){
/* HERE */ Intent intent = new Intent(getBaseContext(), AlarmService.class);
final int _id = (int) System.currentTimeMillis();
/* HERE */ PendingIntent pendingIntent = PendingIntent.getService(this,_id,intent,PendingIntent.FLAG_ONE_SHOT);
AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
......
.....
Now Intent Service class:
public class AlarmService extends IntentService {
PowerManager powerManager;
PowerManager.WakeLock wakeLock;
public AlarmService() {
super("");
}
#Override
protected void onHandleIntent(Intent intent) {
powerManager = (PowerManager) getSystemService(POWER_SERVICE);
wakeLock = powerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "FCFCFCFC");
wakeLock.acquire();
addNotification();
sendMAIL();
}
public void addNotification() {
NotificationCompat.Builder builder =
new NotificationCompat.Builder(getApplicationContext())
.setSmallIcon(R.drawable.icon_transperent)
.setLights(GREEN, 700, 700)
.setContentTitle("Achieve - Alert!")
.setContentText("This is a reminder for your deadline!");
Intent notificationIntent = new Intent(getApplicationContext(), MainMenu.class);
PendingIntent contentIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent,
PendingIntent.FLAG_UPDATE_CURRENT);
builder.setContentIntent(contentIntent);

Now, Manifest add:
<uses-permission android:name="com.android.alarm.permission.SET_ALARM"/>
<uses-permission android:name="android.permission.WAKE_LOCK"/>
<service android:name=".AlarmService" android:exported="true" android:enabled="true"/>

Service don't run like it should on real device

Problem is when I run service on emulator(android 4.0.3), then all is working(data is sent once per hour), but when i run it on my phone it's start sending data every minute. I can't figure out why, hope someone can help me with this.
The service is sending data to http://gprsbtn.herokuapp.com/coordinates where it's going to database.
