Body
<code>installed</code> is declared only in <code>doInBackground</code>, so it's not visible into <code>onPostExecute</code>. Instead of returning a <code>String</code> in <code>doInBackground</code> (where in fact you always return <code>null</code>), you should return a <code>boolean</code> (which would be <code>installed</code>), and in <code>onPostExecute</code> change the parameter for a <code>boolean</code> and test it instead of testing <code>installed</code>. EDIT Taking more time to update my answer : First, I agree with @codeMagic, you definitely DON'T need an <code>AsyncTask</code> to do that ! But if you really want to do it this way, here is how you could do it : first, you should change the signature of your <code>AsyncTask</code> this way : <pre><code>class asynctask extends AsyncTask<String, String, Boolean> { </code></pre> Then in <code>doInBackground</code>, change the return value and instead of returning <code>null</code>, return <code>installed</code> : <pre><code>@Override protected boolean doInBackground(String... arg0) { final SharedPreferences settings = getSharedPreferences("pref_name", 0); boolean installed = settings.getBoolean("installed", false); return installed; }}} </code></pre> And finally, change the parameter of <code>onPostExecute</code> to accept a <code>boolean</code> : <pre><code>protected void onPostExecute(boolean installed) { </code></pre> This way, you can test <code>installed</code> in your method.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
