<p>See <a

Debug</a> and <a
href="https://android.googlesource.com/platform/bionic/+/master/libc/malloc_debug/README_api.md">Native
Memory Tracking using libc Callbacks</a> for a thorough description of the
debugging options available for native memory issues.</p>

<h2 id="ddms">Dalvik Debug Monitor Server</h2>

<p>You can also use the <a
href="https://developer.android.com/studio/profile/ddms.html">Dalvik Debug
Monitor Server</a> (DDMS) to obtain a graphical view of Malloc Debug
output.</p>

<p>To use DDMS, first turn on its native memory UI:</p>
<ol>
<li>Open <code>~/.android/ddms.cfg</code></li>
<li>Add the line: <code>native=true</code></li>
</ol>

<p>Upon relaunching DDMS and selecting a process, you can switch to the new
native allocation tab and populate it with a list of allocations. This is
especially useful for debugging memory leaks.</p>
