How to dismiss AlertDialog.Builder?

Question

In the following code below, how do I dismiss the alert box? I don't want to cause a memory leak. I tried the .dismiss() on alertDialog, but that didn't work... Thanks

// User pressed the stop button public void StopMsg_button_action(View view){     final EditText password_input = new EditText(this); // create an text input field     password_input.setHint("Enter Password"); // put a hint in it     password_input.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD); // change it to password type      AlertDialog.Builder alertDialog = new Builder(this); // create an alert box     alertDialog.setTitle("Enter Password"); // set the title     alertDialog.setView(password_input);  // insert the password text field in the alert box     alertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() { // define the 'OK' button         public void onClick(DialogInterface dialog, int which) {              String entered_password = password_input.getText().toString();              if (entered_password.equals(my_password)) {                 locManager.removeUpdates(locListener); // stop listening for GPS coordinates                 startActivity(new Intent(Emergency_1Activity.this,Main_MenuActivity.class)); // go to main menu              } else {                  alert("Incorrect Password");              }         }      });     alertDialog.setNeutralButton("Cancel", new DialogInterface.OnClickListener() { // define the 'Cancel' button         public void onClick(DialogInterface dialog, int which) {          }      });     alertDialog.show(); // show the alert box }

What didn't work about dismiss()?

You should be able to use either Dialog.dismiss(), or Dialog.cancel()

alertDialog.setNeutralButton("Cancel", new DialogInterface.OnClickListener() { // define the 'Cancel' button     public void onClick(DialogInterface dialog, int which) {         //Either of the following two lines should work.         dialog.cancel();         //dialog.dismiss();     }  });
