Answer 1

The leak comes because you keep the link to the activity after it is destroyed, so use

 if(progressDialog !=null) { progressDialog = null; } progressDialog = new ProgressDialog(this.getApplicationContext()); progressDialog.setMessage("Uploading data, please wait..."); 

OR

use it, it will help

 @Override public void onClick(View v) { switch (v.getId()) { case R.id.btnSubmitNow: // Submit now // Sample upload image UploadImage.uploadImage("testimage"); new AsyncTask<Void, Void, Void>() { // called before execution // main/UI thread protected void onPreExecute() { progressDialog = new ProgressDialog(SignOut_Activity.this); progressDialog.setMessage("Uploading data, please wait..."); progressDialog.show(); }; @Override protected Void doInBackground(Void... params) { // Submit the store data StoreData.postData(StoreList_Activity.storesList .get(StoresListAdapter.Position)); return null; } // on store data uploaded // main/UI thread protected void onPostExecute(Void result) { progressDialog.dismiss(); setSignOut(); StoreList_Activity.storesList .get(StoresListAdapter.Position).isSubmitted = true; SignOut_Activity.this.finish(); }; }.execute(); 

Answer 2

Why is this error ...?

this error occurs if you keep a link to an unused activity

Decision

remove the link to the progress bar, dialogue ..... etc. after use.

rejecting them or making them equal to zero

you can come close to this when you no longer need it

It is recommended to put it in onStop

  @Override protected void onStop() { super.onStop(); if(_dialog.isShowing()){ _dialog.dismiss(); } if(_dialog != null){ _dialog = null; } } 

Answer 3

Reset the dialog after using it, it will not let your application crash.

 dialog.dismiss(); 

Answer 4

use this code progressDialog.dismiss();

Answer 5

Make sure you cancel () the dialog after using the dialog and before starting the next background process.
