Change this dialog cancel    to dialog dismiss     The solution is to call dismiss   on the Dialog you created in NetErrorPage java 114 before exiting the Activity  e g  in onPause     Views have a reference to their parent Context  taken from constructor argument   If you leave an Activity without destroying Dialogs and other dynamically created Views  they still hold this reference to your Activity  if you created with this as Context  like new ProgressDialog this    so it cannot be collected by the GC  causing a memory leak

The way I got around this issue is by not calling intent within a dialog              use syntax applicable to activity or fragment accordingly                     Override public void onClick DialogInterface dialog  int which        checkvariable  true      getActivity   finish        Override public void onStop         super onStop        if  checkvariable            startActivity intent

Thank you Guys to give me many suggestions  Finally I got a solution  That is i have started the NetErrorPage intent two times  One time  i have checked the net connection availability and started the intent in page started event  second time  if the page has error  then i have started the intent in OnReceivedError event  So the first time dialog is not closed  before that the second dialog is called  So that i got a error      Reason for the Error  I have called the showInfoMessageDialog method   two times before closing the first one    Now I have removed the second call and Cleared error  -

Override     protected void onPostExecute final Boolean success            mProgressDialog dismiss            mProgressDialog   null    setting the value null works for me

The dialog needs to be started only after the window states of the Activity are initialized This happens only after onresume   So call  runOnUIthread new Runnable         showInfoMessageDialog  Please check your network connection   Network Alert          in your OnResume function  Do not create dialogs in OnCreate Edit   use this   Handler h   new Handler     h postDelayed new Runnable             showInfoMessageDialog  Please check your network connection   Network Alert          500     in your Onresume instead of showonuithread

I got this error but it is resolved interesting  As first  i got this error at api level 17  When i call a thread  AsyncTask or others  without progress dialog then i call an other thread method again using progress dialog  i got that crash and the reason is about usage of progress dialog    In my case  there are two results that    I took show    method of progress dialog before first thread starts then i took dismiss    method of progress dialog before last thread ends     So    ProgresDialog progressDialog   new        configure progressDialog   progressDialog show     start firstThread               start lastThread             be sure to finish threads  progressDialog dismiss       This is so strange but that error has an ability about destroy itself at least for me
