    copied!<p>I have few problems with syntax errors here. Below I have an <code>alertDialog</code> with <code>sharedPreference</code> and if you are wonder why I have this in a asynctask you can see this <a href="https://stackoverflow.com/questions/18796561/shared-prefence-for-alert-dialog-is-making-my-application-non-responsive">Shared Prefence for alert dialog is making my application non responsive</a> But the syntax problem is underneath <code>installed</code> in my <code>onPostExecute</code> and it says "<code>installed</code> cannot be resovled to a variable." I also have another one under <code>settings</code> in my <code>onPostExecute</code> that says the same thing as well. I know this may seem like an easy fix to some people but I find this really complicated for someone like me. I also advice you look at the link if you have a better method than the <code>AsyncTask</code> and <code>onResume()</code></p> <pre><code>@Override protected void onResume() { class asynctask extends AsyncTask&lt;String, String, String&gt; { @Override protected String doInBackground(String... arg0) { final SharedPreferences settings = getSharedPreferences("pref_name", 0); boolean installed = settings.getBoolean("installed", false); return null; }}} protected void onPostExecute(String file_ad) { if(!installed){ final AlertDialog.Builder alertDialog = new AlertDialog.Builder(this); alertDialog.setTitle("Title"); alertDialog.setIcon(R.drawable.ic_launcher); alertDialog.setAdapter(new MyAdapter(), null); alertDialog.setPositiveButton("OK", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int which) { SharedPreferences.Editor editor = settings.edit(); editor.putBoolean("installed", true); editor.commit(); } }); alertDialog.show(); } super.onResume(); } </code></pre>
