<dt><strong>Use debugging helper classes</strong></dt>

<dd>Android provides debug helper classes such as {@link android.util.Log

    util.Log} and {@link android.os.Debug} for your convenience. </dd>

<dt><strong>Garbage collection</strong></dt>

<dd>

The debugger and garbage collector are currently loosely integrated. The VM guarantees that any

object the debugger is aware of is not garbage collected until after the debugger disconnects.

This can result in a buildup of objects over time while the debugger is connected. For example,

if the debugger sees a running thread, the associated {@link java.lang.Thread} object is not

garbage collected even after the thread terminates.
