Fehler: Launcherdialogabweisung ist fehlgeschlagen: java.lang.IllegalArgumentException

Question

Ich habe diese Frage früher gestellt here, aber niemand war in der Lage, diese auch zu beantworten. Das Problem ist, dass in meiner Tätigkeit onCreate ich einen Alarm Dialog erschaffe und diese Methode läuft perfekt auf Android 5.0, aber in Android API weniger als 5 Ich erhalte eine Fehlermeldung:

Logcat:

E/HwLauncher: Launcher dialog dismiss failed : java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog 

unten ist mein Code für die Aktivität

private static int SPLASH_TIME_OUT = 3000; 

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

     // Alert Box 

     final AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setTitle("Internet not connected"); 
     builder.setMessage("You need to connect WiFi/Mobile-Data run this app."); 
     builder.setCancelable(false); 

     builder.setPositiveButton(
       "Go to Settings", 
       new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 

         startActivity(new Intent(Settings.ACTION_SETTINGS)); 
         finish(); 
        } 
       }); 

     builder.setNegativeButton(
       "Cancel", 
       new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         finish(); 
        } 
       }); 
     final AlertDialog alert = builder.create(); 
     alert.show(); 

     ConnectivityManager cm = (ConnectivityManager) 
       getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); 
     NetworkInfo networkInfo = cm.getActiveNetworkInfo(); 

     if (networkInfo != null){ 

      alert.dismiss(); 
      new Handler().postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        // This method will be executed once the timer is over 
        // Start your app main activity 
        Intent i = new Intent(splash.this, LoginActivity.class); 
        startActivity(i); 
        // close this activity 
        finish(); 
       } 
      }, SPLASH_TIME_OUT); 

     } 
    } 

ich habe versucht, andere Antworten von Stackoverflow like this one aber keine dieser Antworten half mir

EDIT:

Ich habe den AlertDialog-Teil des Codes auskommentiert, aber der Fehler besteht immer noch. Unten ist der Code, den ich jetzt ohne bin mit Alertdialog

public class splash extends AppCompatActivity { 

    private static int SPLASH_TIME_OUT = 3000; 

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


     new Handler().postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       // This method will be executed once the timer is over 
       // Start your app main activity 
       Intent i = new Intent(splash.this, LoginActivity.class); 
       startActivity(i); 
       // close this activity 
       finish(); 
      } 
     }, SPLASH_TIME_OUT); 
     // Alert Box 

     /* 
     final AlertDialog.Builder builder = new AlertDialog.Builder(this); 
     builder.setTitle("Internet not connected"); 
     builder.setMessage("You need to connect WiFi/Mobile-Data run this app."); 
     builder.setCancelable(false); 

     builder.setPositiveButton(
       "Go to Settings", 
       new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 

         startActivity(new Intent(Settings.ACTION_SETTINGS)); 
         finish(); 
        } 
       }); 

     builder.setNegativeButton(
       "Cancel", 
       new DialogInterface.OnClickListener() { 
        public void onClick(DialogInterface dialog, int id) { 
         finish(); 
        } 
       }); 

     final Dialog alert = builder.create(); 
     alert.show(); 

     //WifiManager wifi =(WifiManager)getApplicationContext().getSystemService(Context.WIFI_SERVICE); 

     ConnectivityManager cm = (ConnectivityManager) 
       getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE); 
     NetworkInfo networkInfo = cm.getActiveNetworkInfo(); 


     if (networkInfo != null){ 

      alert.dismiss(); 
      new Handler().postDelayed(new Runnable() { 
       @Override 
       public void run() { 
        // This method will be executed once the timer is over 
        // Start your app main activity 
        Intent i = new Intent(splash.this, LoginActivity.class); 
        startActivity(i); 
        // close this activity 
        finish(); 
       } 
      }, SPLASH_TIME_OUT); 

     }*/ 
    } 

Auch mit dem Alertdialog aus Logcat kommentiert zeigt den gleichen Fehler:

Launcher dialog dismiss failed : java.lang.IllegalArgumentException: no dialog with id 1 was ever shown via Activity#showDialog

       alert.show(); 
      } 
     } else { 
      alert.show(); 
     } 
    } 
} 

ich so versucht und es funktioniert. unten ist meine gradle Datei

    } 
    buildTypes { 
     release { 
      minifyEnabled false 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' 
     } 
    } 
}
