I connect my android phone to eclipse. And I see these message from Logcat.
Can you please tell me what does is the difference between ‘GC_EXPLICIT’ and ‘GC_EXTERNAL_ALLOC’? and what does “45% free” mean?

    I would highly suggest giving the Memory Management video presentation from Google I/O 2011 a watch:

    http://www.youtube.com/watch?v=_CruQY55HOk

    At about 14 minutes in, he goes in to depth on exactly what these mean in the logcat output.

    GC Explicit basically means that an app has explicitly called System.gc();

    GC Concurrent is triggered when your heap starts to fill up and a Concurrent GC kicks in to hopefully clear memory before it fills up.
