How do you find an Android module by name in AOSP?

I am building AOSP Kitkat (4.4) and trying to find the Android.mk file that defines the libnfc-nci module. The libnfc_nci_jni module depends on this local shared library (Android.mk included below) and I want to see the source that generates this .so file. I know that the nfc.h exists in /hardware/libhardware/include/hardware/nfc.h, but that is only the headers.
As far as I know, the available tools for searching android source code are cgrep, jgrep, and resgrep. However, (to my knowledge) these don't search Android.mk files. Is there a tool that I'm missing that I can use to find the directory that contains the module libnfc-nci?
Here is the Android.mk for libnfc_nci_jni (found in /packages/apps/Nfc/nci/jni/Android.mk)
VOB_COMPONENTS := external/libnfc-nci/src
NFA := $(VOB_COMPONENTS)/nfa
NFC := $(VOB_COMPONENTS)/nfc

LOCAL_MODULE_TAGS := optional

I am running Ubuntu 14.04

I found libnfc-nci in /external/libnfc-nci after some more googling. It seems there is no better tool to search aosp for a module than google (unless you write your own script).
As Gabe Sechan noted, a grep solution is possible. Here is the command I used that seemed to do the trick (working directory is the root of AOSP).
grep -inIEr "LOCAL_MODULE := libnfc-nci" .

You should try :
godir libnfc-nci
It should give you options in case thete ae several such directories

Unable to compile harfbuz_ng library using NDK

I am developing an application in which i am using indic-text-renderer for devnagri text renderering.As this is NDK library;i am trying to compile it using ndk-build command.
But it gives me following error:
Android NDK: Trying to define local module 'harfbuzz_ng' in /cygdrive/d/Project_WorkSpace/indic-text-renderer//jni/harfbuzz-ng/Android.mk.
Android NDK: But this module was already defined by /cygdrive/d/Project_WorkSpace/indic-text-renderer//jni/harfbuzz-ng/Android.mk.
My android.mk file is:

How can i resolve this error?
I am very new to the NDK programming,so pls let me know if this information is not sufficient

I tried removing the entire BUILD_SHARED_LIBRARY block and it stopped complaining about re-defining problem,because I wanted to compile harfbuzz-ng just as a static library. You may give it a try.
The last time I got this error,is when I cross compile freetype and use it as a PRE-built static library in my project,I exported the NDK-MODULE-PATH and yet there's a line in my jni/Android.mk written include $(MY_LOCAL_PATH)/freetype/Android.mk
So I just comment out this line and everything works fine.
Because when you set NDK-MODULE-PATH , the compiler will look into your PATH directory and search for Android.mk and compile the source with it. please reference this,and I hope it will help you .

and I have a build.sh file in my jni directory,which will exort my freetype module,quite simple:
export NDK_MODULE_PATH=/home/***/workspace/indic-text-renderer/jni

Besides all this, you will have to cross-compile freetype library.
Wish you good luck, it costs me almost a week.

Static Library Android

I'm trying to build the libpng library into a static library on Android, but it's not working! Every time I try to build it, it doesn't do anything. Below is the android make file
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_CFLAGS :=
LOCAL_MODULE := libpng
LOCAL_SRC_FILES :=\

pngwtran.c \
pngwutil.c
LOCAL_LDLIBS := -lz
include $(BUILD_STATIC_LIBRARY)
And if I change the last line to
include $(BUILD_SHARED_LIBRARY)
it builds correctly! Any help?

In the same directory make an Application.mk file and enter the line:
APP_MODULES := your-android-library-as-defined-in-Android.mk

Crash when launching project with two .so files

libTheGame.so

Do you have any idea how can I deal with this :/ ?
I looked into similar questions, but them don't help me.

I had very similar problem. Finally ended up compiling libraries in separate mk files.
I think this answer might help you. Android NDK linking

Issue trying to build PocketSphinx for Android using the NDK on Windows with Cygwin

I'm currently trying to build the PocketSphinx library for Android using the NDK on Windows with Cygwin. I have the PocketSphinxAndroidDemo project code. I also have the pocketsphinx and shpinxbase projects as sub folders of the E:/Development/CMUSphinx folder.
I'm trying to build using ndk-build from the project folder. The Android.mk file in the /jni/ folder of the project looks like this -
# Build the native component of the PocketSphinx library for Android.
# You MUST change this to the absolute path of the directory containing
# sphinxbase and pocketsphinx source code.
SPHINX_PATH := E:/Development/CMUSphinx

I can build all the ndk samples just fine. Any clue what's causing this error? Many thanks in advance!

Jason, Edit jni/Android.mk file
Change Line 162 :
LOCAL_STATIC_LIBRARIES := sphinxutil sphinxfe sphinxfeat sphinxlm pocketsphinx
to :
LOCAL_STATIC_LIBRARIES := pocketsphinx sphinxlm sphinxfeat sphinxfe sphinxutil
That will resolve your issue.

Do you know if this project has been previously built using cygwin with success? Cygwin has a number of oddities, from the awkward combination of windows drive letters with unix paths, to interpreting an inadvertent double slash in an assembled path unusually, and more. You could try the /cygdrive/e/ type of path instead of a drive letter, but who knows if that will help.

Jason,
you have to change your sphinx path to cygwin format i.e without ":"
change
SPHINX_PATH := E:/Development/CMUSphinx
to
SPHINX_PATH := /cygdrive/e/Development/CMUSphinx
this will fix the error

I used following link for Building Pocketsphinx On Android On Windows
https://sites.google.com/site/opiatefuchs/home/pocketsphinxandroiddemo but it misses one step that #Hitesh mentioned about replacing LOCAL_STATIC_LIBRARIES in jni/Android.mk file and I was able to build to latest 0.8 version.. thanks #Hitesh
