How to import a .so Library in Android.mk when i build APK

I have this problem: I have to build my app using the Android.mk file and I have to insert the library "libcom_google_ase_Exec.so" inside the final apk, but I can't do it. What I get is an APK that doesn't contain the library and therefore the app doesn't work.
The code for the Android.mk I'm currently using is:
#ifneq ($(TARGET_BUILD_PDK), true)
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := com_google_ase_Exec
LOCAL_SRC_FILES := app/src/main/jniLibs/armeabi/libcom_google_ase_Exec.so

include $(BUILD_MULTI_PREBUILT)
#include $(call all-makefiles-under, $(LOCAL_PATH))
#endif
The folder structure within my project is as follows:
In the root i have:
--> /app and Android.mk
In the app folder i have:
--> app/src/main/jniLibs/armeabi/libcom_google_ase_Exec.so
How can i change the Android.mk file to import the .so library in the final APK?

I solved in this way, i build a 64bit version.
If u need a 32bit version u can uncomment all LOCAL_MULTILIB = 32.

The problem addressed here is not relavant to what i am facing, though the error is similar.
The error i got is:
Android NDK: jni/inner/Android.mk:mylib: LOCAL_MODULE_FILENAME should not include file extensions
Android NDK: jni/inner/Android.mk:mylib: LOCAL_MODULE_FILENAME must not contain a file extension
Please help!!
[So often i am meeting headless problems!!]

You need to ensure that you call include $(CLEAR_VARS) after you include the make files which build your static libs. The auto generation of the module file name only works if that variable is empty, and your previous make file includes end up defining it when you call $include ($BUILD_STATIC_LIBRARY)

Try using LOCAL_MODULE_FILENAME := libavcodec LOCAL_MODULE_FILENAME += libavutil instead of LOCAL_SRC_FILES += libavcodec.a libavutil.a in your jni/Android.mk.

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:

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

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.

When I run the ndk-build command I get the following error:
build-binary.mk:197: *** target pattern contains no '%'. Stop.
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
