Broadcast Reveiver not being called from Alarm Manager

Question

I've searched the archives and still can't resolve my issue.

I'm trying to take an user input in seconds that will call the broadcast receiver to create a toast message and vibrate the phone. However, the broadcast receiver is never called and I can't figure it out. My code is below.

Thanks!

package com.example.cs984x.alrm;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Intent;
import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.text.Editable;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Button btn1 = (Button) findViewById(R.id.button1);
    btn1.setOnClickListener(new View.OnClickListener() {
        @Override
         public void onClick(View v) {
            EditText inputSeconds = (EditText) findViewById(R.id.editText1);
            int inputTime = Integer.parseInt(inputSeconds.getText().toString());
            Toast.makeText(MainActivity.this, "The alarm will go off in " + inputTime + " seconds.", Toast.LENGTH_LONG).show();
            AlarmManager alarmManager = (AlarmManager)getSystemService(Context.ALARM_SERVICE);
            Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
            myIntent.setAction("com.example.cs984x.alrm.vibrate");
            PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);
            alarmManager.set(AlarmManager.RTC_WAKEUP,   System.currentTimeMillis()+(inputTime*1000), pendingIntent);


        }
    });
}
}

Broadcast Receiver Class:

package com.example.cs984x.alrm;

import android.app.AlarmManager;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Vibrator;
import android.widget.EditText;
import android.widget.Toast;

import static android.content.Context.ALARM_SERVICE;


public class MyReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

    Toast.makeText(context, "Your time is up", Toast.LENGTH_LONG).show();
    Vibrator v;
    v= (Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
    v.vibrate(2000);

}

}

Add action to intent:

Intent myIntent = new Intent(MainActivity.this, MyReceiver.class);
myIntent.setAction("YourPackageName.YourAction");
            PendingIntent pendingIntent =PendingIntent.getBroadcast(MainActivity.this, 0, myIntent,0);

in AndroidManifest:

<intent-filter>
                <action android:name="YourPackageName.YourAction" />
            </intent-filter>
