I am having a bit of confusion regarding the function of RAM and ROM within the Android machine. For reference, I'll pick my phone, a Motorola Droid (original), though I guess the question applies to all Android machines.
I am trying to write an article on how Android memory is used, (and once and for all what should we think about CompCache and Swap) The prototype is here: http://forum.xda-developers.com/showthread.php?t=897823 I believe this thing is riddled with major technical errors, but I can't find the actual information. My Google-fu is weak. I would appreciate a technical review if any one want to comment there. In the meanwhile, here's a few related questions. According to Motorola specs on Motodev, it has 512MB of ROM, and 256MB of RAM. From Eneas, I found the boot process explained ( http://www.androidenea.com/2009/06/android-boot-process-from-power-on.html ) I guess my question is what exactly happens when Android loads a program? And what's the ROM loaded with? In the 512MB ROM, is 256MB ROM loaded with boot stuff and system stuff, and the other 256MB for app storage? (Is that what DiskUsage app sees?) How do I read what's in RAM itself? I have CM612 loaded and I have terminal so I can see Busybox output. "Free" doesn't tell me very much. I can do ADB. Which rooted app tells me more? I tried both AutoKiller and Auto Memory Manager, and they give very similar outputs, but I'm not quite understanding them under "processes". What exactly is that "free memory" under Advanced Task Killer? (ATK Froyo by ReChild) It doesn't agree with the numbers I find under "free" in Busybox. How do I interpret that little bar graph at the bottom of "Manage Services"? I figured "red" is system like gapps, acore, and so on, but what is yellow and green? Is green the services and apps that can be killed? Can compcache and swap be activated together? Or are they mutually exclusive? Just how efficient is compcache? Sorry for the messy questions. I seems there is no consensus on task killers, compcache and swap. A lot of this stuff seem to be related by anecdotes instead of actual technical info.
