Question

Below is my code.
I want to set it disable auto change screen orientation.
And enable auto change screen orientation.

class NewLoad extends AsyncTask<String, String, String> {
        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            progDailog = new ProgressDialog(this);
            progDailog.setMessage("test");
            progDailog.setIndeterminate(false);
            progDailog.setProgressStyle(ProgressDialog.STYLE_SPINNER);
            progDailog.setCancelable(false);
            progDailog.show();
            //set disable auto change
        }

        @Override
        protected String doInBackground(String... aurl) {
            //do something
            return null;
        }

        @Override
        protected void onPostExecute(String unused) {
            super.onPostExecute(unused);
            progDailog.dismiss();
            //set enable auto change
        }
    }

How can I do it?

Make your activity to look something like this in manifest

  <activity
                android:name=".Hello"
                android:label="@string/app_name"
                android:screenOrientation="portrait"   <-- Screen will be forced to have portrait
                android:configChanges="orientation|keyboardHidden|screensize" > <-- No Restart in these cases

ScreenSize attribute seems to be added in 4.0 so don’t mentioned it if you are ruuning below 4.0.
