TimedNotification

I have an app where I want a daily notification to be sent at 8:00 AM because this is when I will update the website that the app connects to. I spent a few hours researching and after a couple of headaches and looking at a lot of examples I settled for this but something is wrong. Can someone help me sort it out.

This is my MainActivity

package com.subjectofthought.subjectofthought;

import android.app.AlarmManager;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.support.annotation.RequiresApi;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.app.NotificationCompat;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

import java.util.Calendar;

public class MainActivity extends AppCompatActivity {

    private WebView webview;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        webview = (WebView)findViewById(R.id.webView);
        WebSettings webSettings = webview.getSettings();
        webSettings.setJavaScriptEnabled(true);
        webview.loadUrl("http://opensourceco.com/");
        webview.setWebViewClient(new WebViewClient());
    }

    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    Intent alarmIntent = new Intent(this, NotificationBroadcastReceiver.class); // AlarmReceiver1 = broadcast receiver

    PendingIntent pendingIntent = PendingIntent.getBroadcast(MainActivity.this, 0, alarmIntent, PendingIntent.FLAG_UPDATE_CURRENT);
        alarmIntent.setData((Uri.parse("custom://"+System.currentTimeMillis())));
        alarmManager.cancel(pendingIntent);

    Calendar alarmStartTime = Calendar.getInstance();
    Calendar now = Calendar.getInstance();
        alarmStartTime.set(Calendar.HOUR_OF_DAY, 8);
        alarmStartTime.set(Calendar.MINUTE, 00);
        alarmStartTime.set(Calendar.SECOND, 0);
        if (now.after(alarmStartTime)) {
        Log.d("Hey","Added a day");
        alarmStartTime.add(Calendar.DATE, 1);
    }

  alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, alarmStartTime.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);
         Log.d("Alarm","Alarms set for everyday 8 am.");


}

My BroadcastReceiver

package com.subjectofthought.subjectofthought;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;

/**
 * Created by gener on 1/27/2018.
 */

public class NotificationBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Intent intent1 = new Intent(context, IntentService.class);
        intent1.setData(Uri.parse("custum://"+System.currentTimeMillis()));
        context.startService(intent1);
    }
}

My IntentService

package com.subjectofthought.subjectofthought;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.content.res.Resources;
import android.graphics.BitmapFactory;
import android.media.RingtoneManager;
import android.net.Uri;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.NotificationManagerCompat;
import android.support.v7.app.NotificationCompat;
import android.util.Log;

/**
 * Created by gener on 1/27/2018.
 */

public class IntentService extends android.app.IntentService {

    private int NOTIFICATION_ID = 1000;

    protected void onHandleIntent(Intent intent) {
        Context context = this.getApplicationContext();
        NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        Intent mIntent = new Intent(this, MainActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("test", "test");
        mIntent.putExtras(bundle);
        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, mIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        Resources res = this.getResources();
        NotificationCompat.Builder builder = new NotificationCompat.Builder(this);
        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM);
        Notification notification = new NotificationCompat.Builder(this)
                .setContentIntent(pendingIntent)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(BitmapFactory.decodeResource(res, R.mipmap.ic_launcher))
                .setTicker("ticker value")
                .setAutoCancel(true)
                .setPriority(8)
                .setSound(soundUri)
                .setContentTitle("SubjectOfThought")
                .setContentText("New Topic for Today").build();
        notification.flags |= Notification.FLAG_AUTO_CANCEL | Notification.FLAG_SHOW_LIGHTS;
        notification.defaults |= Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE;
        notification.ledARGB = 0xFFFFA500;
        notification.ledOnMS = 800;
        notification.ledOffMS = 1000;
        notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
        notificationManager.notify(NOTIFICATION_ID, notification);
        Log.i("notif","Notifications sent.");

    }
}

Finally figured out how to do it from a youtube video. I think people were overthinking this a lot.
