    <p>I'd like to create an AsyncTask that sits in the background and calls a web service every X seconds.</p> <pre><code> private class BackgroundTask extends AsyncTask&lt;Integer, Integer, Boolean&gt; { protected Boolean doInBackground(Integer... params) { if (params.length &gt; 0) { int intUserId = params[0]; if (intUserId != -1) { boolean blnRunning = true; while (blnRunning) { // perform query try { this.wait(15000); } catch (InterruptedException e) { blnRunning = false; } } } } return false; } protected void onPostExecute(Boolean blnLaunchStoreFavorites) { // do something? } } </code></pre> <p>This is what I have.</p> <p>Shortly after this.wait() is called, I get an error down in the bowels of ThreadPoolExecuter.class.</p> <pre><code>Uncaught handler: thread AsyncTask #2 exiting due to uncaught exception java.lang.RuntimeException: An error occured while executing doInBackground() at android.os.AsyncTask$3.done(AsyncTask.java:200) at java.util.concurrent.FutureTask$Sync.innerSetException(FutureTask.java:273) at java.util.concurrent.FutureTask.setException(FutureTask.java:124) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:307) at java.util.concurrent.FutureTask.run(FutureTask.java:137) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1068) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:561) at java.lang.Thread.run(Thread.java:1096) </code></pre> <p>I'm not quite sure what is going on here. Any ideas?</p>

    1. COTry putting another catch block after the one for InterruptedException but have it catch Exception and then use printStackTrace to see what exception is being thrown.

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.

SQuiL has stopped working due to an internal error.

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