Ich arbeite mit einer Android-Anwendung, um Netzwerkfehler anzuzeigen.

NetErrorPage.java

package exp.app;

import android.app.Activity;
import android.app.AlertDialog;
import android.content.Context;
import android.content.DialogInterface;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class NetErrorPage extends Activity implements OnClickListener {    

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.neterrorlayout);
        Button reload=(Button)findViewById(R.id.btnReload);
        reload.setOnClickListener(this);    
        showInfoMessageDialog("Please check your network connection","Network Alert"); 
    }

    public void onClick(View arg0)             
        {
            if(isNetworkAvailable())
            {                   
                Intent myIntent = new Intent((Activity)NetErrorPage.this, MainActivity.class);   
                myIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);              
                ((Activity)NetErrorPage.this).startActivity(myIntent);
                finish();
            }
            else
                showInfoMessageDialog("Please check your network connection","Network Alert");
    }

    public void showInfoMessageDialog(String message,String title)
       {
        AlertDialog alertDialog = new AlertDialog.Builder(NetErrorPage.this).create();
        alertDialog.setTitle("Network Alert");
        alertDialog.setMessage(message);
        alertDialog.setButton("OK",
                new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog,int which) 
                    {   
                        dialog.cancel();
                    }
                });            
        alertDialog.show();
    }

 private boolean isNetworkAvailable()
    {
        NetworkInfo ActiveNetwork;
        @SuppressWarnings("unused")
        String IsNetworkConnected;
        @SuppressWarnings("unused")
        String ConnectionType;
        ConnectivityManager connectivitymanager;
        connectivitymanager=(ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);        
        try
        {           
            ActiveNetwork=connectivitymanager.getActiveNetworkInfo();
            ConnectionType=ActiveNetwork.getTypeName(); 
            IsNetworkConnected=String.valueOf(ActiveNetwork.getState());
            return true;                        
        }
        catch(Exception error)
        {
                return false;
        }
    }    
}

aber ich erhalte den Fehler wie unten,

Ich habe mehr gesucht ... aber ich habe keine richtige Idee, dies zu klären.

Ich möchte, dass beim Laden dieser Seite ein Layout hinzugefügt und ein Dialogfeld angezeigt wird.

Bitte helfen Sie mir, diesen Fehler zu beheben

Hinweis: Ich habe das auch versucht

@Override
    protected void onResume() {
    super.onResume();
        runOnUiThread(new Runnable() {
            public void run() {
                showInfoMessageDialog("Please check your network connection","Network Alert");
            }
        });

    }
