I am working with Android application to show network error.

NetErrorPage.java

package exp.app;

import android.app.Activity;
impor         


        

Answer 1

 @Override
    protected void onPostExecute(final Boolean success) {
        mProgressDialog.dismiss();
        mProgressDialog = null;

setting the value null works for me
