POHaving two activities with Mainctivity causes the back button to not work properly

Body
copied!<p>I have a MainActivity and I am posting partial code here:</p> <pre><code>@Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection switch (item.getItemId()) { case R.id.action_quit: moveTaskToBack(true); return true; case R.id.action_help: //display the help activity Intent myIntent = new Intent( this, ShowHelp.class); startActivityForResult(myIntent, 0); return true; case R.id.action_about: //display the about window //aboutApp(); return true; default: return super.onOptionsItemSelected(item); } } public void aboutApp() { // custom dialog final Dialog dialog = new Dialog(this); dialog.setContentView(R.layout.about); dialog.setTitle("About TollCulator"); TextView textViewAbout = (TextView) dialog.findViewById(R.id.tvContents); textViewAbout.setText("About: "); textViewAbout.append("\n\tTollCulator - Toll Calculator"); textViewAbout.setMovementMethod(new ScrollingMovementMethod()); Button btnCloseIt = (Button) dialog.findViewById(R.id.btnOk); // if button is clicked, close the custom dialog btnCloseIt.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { dialog.dismiss(); } }); ImageView iv1 = (ImageView) dialog.findViewById(R.id.imgFB); iv1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Uri uri = Uri.parse("https://www.facebook.com/PagesByZ");); Intent intent = new Intent(Intent.ACTION_VIEW, uri); dialog.cancel(); startActivity(intent); } }); dialog.show(); } </code></pre> <p>ShowHelp.class partial code here which is an Activity on it's own:</p> <pre><code>@Override public boolean onOptionsItemSelected(MenuItem item) { switch(item.getItemId()) { case 16908332: Intent myIntent = new Intent(getApplicationContext(), MainActivity.class); startActivityForResult(myIntent, 0); //finish(); } return super.onOptionsItemSelected(item); } @Override public void onBackPressed() { // do something on back. Intent myIntent = new Intent(getApplicationContext(), MainActivity.class); startActivityForResult(myIntent, 0); //finish(); return; } </code></pre> <p>Now when i choose <code>action_help</code> from the menu it opens the ShowClass Activity and I can press the back button and it brings me back to MainActivity without any problem.</p> <p>Now If I choose <code>action_about</code> the About Dialog pops up and If I click on the icon within the Dialog the following pops up: <img src="https://i.stack.imgur.com/uZzA7.png" alt="enter image description here"></p> <p>At this time If I decide to press BACK, instead of closing the pop and displaying my About Dialog, I am just taken to the Homescreen.</p> <p><strong>Commenting the <code>finish();</code> method in ShowClass allows me to click the BACK button from the "Complete action using" But instead of taking me to the MainActivity, it takes me to ShowClass from there I can press the Back button again to come back to MainActivity. So as long as I choose <code>action_help</code> first, pressing back brings me back to the ShowHelp.</strong></p> <p>When the Complete action using pops up from the About Dialog, I set up a Log, and it's on the onPause() state and if I did not run ShowHelp in the beginning, my App goes directly to onStop() and onDestroy().</p> <p>Please help me fix the issue.</p> <p>To test it, I created a demo without the ShowHelp class with just the dialog and By pressing back button, the Complete actiong using dialog closes and then pressing back again closes the About Dialog. So I am not sure what is going on.</p>
