Android 设备正在执行内存清理时，进度对话框未旋转

大家好，我需要从数据库中获取1200条记录，所以我已经为retrevind数据编写了AsyncTask。这是我的代码

 new AsyncTask<Integer, Integer, Integer>(){
                  @Override
                    protected void onPreExecute() {
                               pd=ProgressDialog.show(CasePersonScreen.this, "Please Wait", "Getting Case Persons");
                               pd.setIndeterminate(true);           
                          }
                @Override
                    protected Integer doInBackground(Integer... params) {
                        // **Code** performing database operations
                        CasePersonArryList = objBLParentToChildCommonOperations.getCasePersons(objCase);
                        return 1;
                    }
                   @Override
                    protected void onPostExecute(Integer arg0) {
                        if(pd!=null&&pd.isShowing())
                        {
                            pd.dismiss();
                        }
     }.execute(1,1,1);

请帮我解决这个问题

提前感谢

您可能在主线程中执行了一项繁重的任务，导致UI卡住。你能发布你的全部主要活动吗？

没有安卓专家，但我敢肯定，除了主线程，你不能进行任何UI操作。我认为您必须从异步线程向主UI线程发送某种消息。尝试在crunchs中获取数据..解决了我的问题，在onPostExecute（）中调用了另一个巨大的db操作，现在将代码转移到doinBackground解决了问题
