我在代码中遇到了以下异常...

我不太明白为什么会出现这个错误。它会导致设备强制关闭的问题。有什么办法可以修复吗?谢谢。
这是我的代码...
public class SearchWord extends Activity {
/** Called when the activity is first created. */
private ProgressDialog progressDialog;
...
}
public void callDialog(){
this.progressDialog = ProgressDialog.show(SearchWord.this,null, "Loading. Please wait..", true);
new Thread(new Runnable(){
public void run(){
try{
Thread.sleep(9000);
}
catch (Exception e){
e.printStackTrace();
}
if(copyFlag){
}
else{
getData();
}
SearchWord.this.handler.sendEmptyMessage(0);
}
}).start();
}
Handler handler = new Handler(){
public void handleMessage(Message msg){
progressDialog.dismiss(); <-- line 718
SetData();
}
};
