    <p>An application background service updates sqlite database. Therefore my activities are becoming outdated. Activity intents also contain outdated params so onCreate, onResume will crash the application. An easiest solution is to restart whole application. I don't want to add IFs to all onCreate, onResume methods in all activities to handle one special case.</p> <p>I noticed that <a href="https://github.com/ACRA/acra" rel="nofollow">ACRA</a> has following code executed after an exception has been handled.</p> <pre><code>android.os.Process.killProcess(android.os.Process.myPid()); System.exit(10); </code></pre> <p>However many people discourage use of <code>System.exit(0)</code>. Is <code>System.exit(0)</code> really that dangerous for an Android application data integrity? Of course my code will close the database before existing.</p> <p><strong>Update:</strong></p> <p>I known how to use <code>finish()</code>, content providers, send broadcasts, read many answers here on SO, etc. However each of these approaches requires additional thousands lines of code. I implemented solution with <code>System.exit(0)</code> in ten minutes. The restart is so fast that it is indistinguishable from ordinary startActivity action. The db update/restart is done after longer user inactivity so the app is already suspended by the system. My app doesn't require real time syncing. During tests the application behaves correctly. This is quick and dirty solution.</p> <p>Therefore I asked the question about possible side effects of <code>System.exit(0)</code>. Not how I can do the design differently. I know that current design is not perfect.</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.
