Android Einstellung Alarm, um einen bestimmten Teil einer Aktivität zu tun

Question

Ich bin neu in Java und das ist mein erster Beitrag hier, also hoffentlich kann mir jemand helfen. Ich habe jede Website überprüft, die in Google gefunden wurde, um die Antwort darauf ohne Glück zu finden. Daher versuche ich, einen Wiederholungsalarm einzurichten, der ab der eingestellten Zeit alle 24 Stunden eine Zufallszahl generiert. Ich verwende den Alarm-Manager und kann nur Code-Beispiele finden, die den Alarm-Manager zum Starten von Aktivitäten oder Diensten verwenden. Ich möchte mit dem Alarm-Manager einen einfachen Befehl ausführen, der bereits in einer Aktivität enthalten ist. (Wenn eine andere Art und Weise Theres dies bitte tun Sie mich bitte)

Hier ist ein Beispiel dafür, was ich habe und was im Versuch

import java.util.Calendar; 
import java.util.Random; 
import android.app.Activity; 
import android.app.AlarmManager; 
import android.app.PendingIntent; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.View; 

public class ExampleCode extends Activity 
{ 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.example); 

     AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);   // Here I want to set an alarm  

     Calendar twentyFourHourCalendar = Calendar.getInstance();  


     twentyFourHourCalendar.set(Calendar.HOUR_OF_DAY, 24);         // At midnight 
     twentyFourHourCalendar.set(Calendar.MINUTE, 0); 
     twentyFourHourCalendar.set(Calendar.SECOND, 0); 

     Intent someIntent = new Intent("com.example.SomeOtherProcess");      // Instead of an activity I want it to run the generateRandom() method below 

     someIntent.putExtra("NotifID", 1);         

     PendingIntent displayIntent = PendingIntent.getActivity(
      getBaseContext(), 0, someIntent, 0);    

     alarmManager.set(AlarmManager.RTC_WAKEUP, 
       twentyFourHourCalendar.getTimeInMillis(), displayIntent); 

     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, twentyFourHourCalendar    // I want it to generate a random number every midnight without any user interaction 
       .getTimeInMillis(), 24 * 60 * 60 * 1000, displayIntent);   

    } 



    public void generateRandom()                // This is the method that I want to repeat 
    { 
     Random generator = new Random(); 
      int randomNumber = generator.nextInt(2); 
    } 



    } 

Alles, was ich tun möchte, zu erreichen, ist die generateNumber() -Methode aufrufen Alle vierundzwanzig Stunden bin ich mir sicher, dass die Lösung sehr einfach ist. Ich denke, ich habe mir den Code zu lange angesehen, um es herauszufinden, lol. Jede Hilfe wird sehr geschätzt werden !!!
