General :: How To Visualize Related Files In Kernel Source

Jan 24, 2014

Is there any way (or what is the best way) to visualize what specific files within a kernel source are inter-related, what files take priority over others, etc? For example, I want to trace from top to bottom the related kernel source files & actions that would be triggered by insertion into a headphone jack, and dig through the code as much as I'm able and try narrowing down the source of a problem. I can (and have) poked around in github, and understand how to compile the kernel, but don't quite have a grasp of the hierarchy of files, drivers, etc. within the source.

If there isn't a way to 'map' out a specific kernel source, any generic flowchart or 'map' created in general for visualizing the inter-relationships of source files within android kernels?

How to compile a kernel, pack into a boot.img, edit a ramdisk, etc., within the last few weeks, but this is a major roadblock in my understanding of kernel source code.

General :: How To Slim A ROM - Find APKs Related Files

Jun 1, 2014

I'm trying to make my own slimmed version of a ROM's .zip, by deleting some APKs and changing some other files (media, bootanaim, walls; minor changes to systemui and framework-res; etc)..

Until now, I've done it several times, but I think that I can do a more in-depth research to reduce junk files..Is there a way to find a list of LIBs and other files that are related to the APKs that I delete??. I've tried two ways:

1) Decompiling APKs and "explore" to find related files

2) Search all over the Web to find information

Android :: Way To Visualize Activity Stack (activities In Memory) On Droid?

Jun 26, 2010

I'm currently debugging my app which is quite complex and has up to 5 activity levels. In order to detect memory leaks (i.e. activities that aren't removed from memory even finish() is called, due to some references held somewhere) I want to check which activities are still alive in memory. Currently I create hprof dumps, but it's not very convenient, cause every time I need to mount the sdcard, copy the hprof dump file from the sdcard to my PC, etc. (Side note: I already tried to automate the pulling of my hprof file more easily, but I'm on an unrooted device and adb pull <hprof file> won't let me / no permission.) Therefore I am wondering, if all I want to know is IF and WHICH activities are still currently alive in my memory, is there a way through the Android API or any other way on-the-fly with which I can achieve this (list all alive activities of my app), programatically.

Android :: Module Version Conflicts Between Wlan Module - Kernel Source

May 17, 2009

I'm tinkering with building and installing Android from source. Basically I've got it down fairly well, but I seem to have run into a bit of a problem with the wlan module, probably from HTC.

Having pulled the 2.6.27 kernel sources and built that with a .config pulled from the phone, and using that as the kernel image instead of the prebuilt one, I get the following wifi failure message in dmesg:

wlan: version magic '2.6.27-00205-gf2dabc0 preempt mod_unload ARMv6 ' should be '2.6.27-00392-g8312baf preempt mod_unload ARMv6 '

probably because the .config I pulled from the phone has:

CONFIG_LOCALVERSION="-00392-g8312baf"

So I rebuilt with the '00205' localversion and now I get in dmesg:

[61.122497] wlan: Unknown symbol trout_pwrsink_set

but trout_pwrsink_set was changed to htc_pwrsave_set way back in February:

[ARM]: trout: Switch from trout_pwrsink -> htc_pwrsink 33/8933/1 http://android.git.kernel.org/?p=kernel/msm.git;a=commitdiff;h=44a01f...

I'm clearly getting an obsolete wlan module somehow, Any ideas for how I can get a wlan module that goes with the '00392' kernel would be appreciated.

Android :: How To Compile All Source Files - Default Make Target Does Not Compile All Of Them

Mar 16, 2010

when I compile android (http://source.android.com/download) it does not compile some source files. For example there is external/bluetooth/bluez/sbc/sbc.c which is not compiled. There are also other such files.

It's possible those files need not to be compiled. Or it might be that I need some special configuration to compile them.

Either way, if it is possible, I'd like to compile them. Is there some way to do it? Maybe some "compile_all" make target? (I believe the reason why I want to compile all source files is not important)

Android :: How To Rebuild Android Source Code? (Files Not Updated)

Nov 1, 2010

I have android source code in my system and it works fine. But when I make some changes in android source files and run "make" it doesn't generate/update any files.
i) System should generate a new system.img file if changes have been made to its source code
ii) Android kernel file-zImage file doesn't change with any change even if we make any changes to the source code

Another question if I create a new library folder inside / libcore it gets automatically picked up when compiling. For creating a new library folder outside /libcore i added its path in /build/core/main.mk and .classpath file. Still its not getting picked up during compilation. Can someone please confirm where all we have to make changes for adding a new library file outside /libcore.
