こんにちは、TabHosts を Progress Dialog で動作させようとしていますが、それぞれのアクティビティで ListView をロードするとこれらのエラーが発生し続けますが、これらのエラーが発生し続けます。

コード：

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

        //final ProgressDialog dialog = ProgressDialog.show(getParent(), "Please wait..", "Doing stuff..", true);
        final ProgressDialog pd = new ProgressDialog(this);
        pd.setMessage("Please wait...");
        pd.show();
        Runnable myRun = new Runnable(){
        public void run(){
            Looper.myLooper().prepare();
            //DO EVERYTHING YOU WANT!
            TabHost tabHost = getTabHost();

            // Tab for All
            TabSpec allspec = tabHost.newTabSpec("All");
            allspec.setIndicator("All", getResources().getDrawable(R.drawable.icon_photos_tab));
            Intent allIntent = new Intent(AndroidTabLayoutActivity.this, AllApplicationsActivity.class);           
            allspec.setContent(allIntent);

            // Tab for Installed Application
            TabSpec systemspec = tabHost.newTabSpec("Installed Applications");
            // setting Title and Icon for the Tab
            systemspec.setIndicator("Applications", getResources().getDrawable(R.drawable.icon_videos_tab));
            Intent systemIntent = new Intent(AndroidTabLayoutActivity.this, SystemApplicationsActivity.class);
            systemspec.setContent(systemIntent);


            // Adding all TabSpec to TabHost
            tabHost.addTab(allspec); 
            tabHost.addTab(systemspec); 

            //Finally
            runOnUiThread(new Runnable() {
            public void run() {


            pd.dismiss();
            }
            });
        }
        };

        Thread T = new Thread(myRun);
        T.start();


    }


}

編集：プログラムを起動するとエラーが発生するようになりました

交換：

Intent allIntent = new Intent(this, AllApplicationsActivity.class);            
Intent systemIntent = new Intent(this, SystemApplicationsActivity.class);

と：

Intent allIntent = new Intent(AndroidTabLayoutActivity.this, AllApplicationsActivity.class);           
Intent systemIntent = new Intent(AndroidTabLayoutActivity.this, SystemApplicationsActivity.class);

のイニシャルがProgressDialog正しくありません。

ProgressDialog pd = new ProgressDialog(getContext());
pd.setMessage(...);
pd.show();
