    <p>It is hard to tell without complete source code exactly what is happening, but perhaps Romain Guy's answer <a href="https://groups.google.com/forum/?fromgroups#!topic/android-developers/G_ngkPTOfRo">here</a> on Google Groups will help.</p> <blockquote> <p><code>onLowMemory()</code>is called when the entire system is running out of memory, not when your process is running out of memory. Each app is limited to a fixed amount of RAM (24 MB on a Nexus One for instance). If you use up these 24 MB but the system still has more RAM available, you will get an<code>OutOfMemoryError</code>but not<code>onLowMemory()</code>.</p> </blockquote> <p>The 24mb limit is pretty much set in stone for applications on &lt; Honeycomb. If you are targeting API 11 or higher you can ask for more memory by declaring that a large heap be allocated for your application. It is not mentioned in documentation but adding <code>android:largeHeap="true"</code> to your <code>application</code> tag in your Manifest.xml will do this (although it is not guaranteed).</p> <p>Note: on modified firmware (custom ROMs) it is possible for that value to be lower or higher. I believe on the Samsung Galaxy Nexus it is 48mb by default, but as a general rule staying within 24mb is a safe assumption. There is also a <a href="http://developer.sonymobile.com/wp/2012/03/30/learn-about-the-technical-differences-between-gingerbread-and-ics/">great post</a> on the Sony Ericsson explaining the technical differences between Gingerbread and Ice Cream Sandwich (RAM is a topic covered in-depth).</p> <p>Good luck, I hope this at least helps you track down the issue.</p>

    2. CO@anDroider It is difficult to tell without your source code what the problem is, but all signs point to some sort of performance issue. If you tried it on a higher-end device running API 11 or higher with largeHeap="true" are these results the same? That, or add some log calls in your native code and see where those stop. Perhaps you have some infinite recursion or loop or memory leak you are unaware of.

    3. COIt's 16mb on the Nexus one, I use: long heap = Debug.getNativeHeapAllocatedSize() / 1024; On apps what allow users to keep loading pictures to stop them before heap gets too close to 16mb, and also keep sending that number to logcat to help debug leaky apps.

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.
