    <p>In my MainActivity I have a class initialization like so:</p> <pre><code>Presentation presentation = new Presentation("link"); </code></pre> <p>Presentation is a class which gets initialized using values from a .JSON file on a web server:</p> <pre><code>public Presentation(String URL) { // Do stuff doNetworking(); } private doNetworking() { // Network access here // This throws the Network on Main Thread exception } </code></pre> <p>In my MainActivity, I need all the values of Presentation to be there in the next step:</p> <pre><code>Presentation presentation = new Presentation(); // Do some stuff with it </code></pre> <p>Using the AsyncTask I am not sure how I should go about doing this, so far I have something like this: public Presentation(String URL) { // Do stuff new InitializePresentation().execute(URL); }</p> <pre><code>private class InitializePresentation extends AsyncTask&lt;String, Void, Boolean&gt; { // Amongst other things protected Boolean doInBackground(String... params) { // Do the networking stuff here } } </code></pre> <p>What I need is to refactor this code so that it is asynchroneous but behaves like a synchroneous call. Any help is greatly appreciated.</p> <p><em>edit</em> How does one refactor a code to accomplish this?</p> <pre><code>Bitmap b = new Bitmap(); Load bitmap from network; Use bitmap in imageview; </code></pre> <p>Can this be used in this fashion? Or do I have to use it like</p> <pre><code>Async, doInBackground() { Load bitmap from network Use bitmap in imageview Continue with application } </code></pre> <p>Thank you!</p>

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
