While trying to create a shared library using android-ndk-r8b it shows the error
Your APP_BUILD_SCRIPT points to an unknown file /home/myLib/ndk1/jni/Android.mk
Android NDK Aborting... .Stop
For my application,I simply created a jni folder which contains a ndk1.c file and Android.mk file
Steps for building library:
export ARM_ROOT=/home/myLib/android-ndk-r8b
export ARM_TOOL=/home/myLib/android-ndk-r8b/toolchains/arm-linux-androideabi-
4.4.3/prebuilt/linux-x86
export ARM_LIB=/home/myLib/android-ndk-r8b/platforms/android-8/arch-arm/usr/lib
export ARM_LIBO=/home/myLib/android-ndk-r8b/toolchains/arm-linux-androideabi-4.4.3/prebuilt/linux-x86/lib/gcc/arm-linux-androideabi/4.4.3
export ARM_INC=/home/myLib/android-ndk-r8b/platforms/android-8/arch-arm/usr/include
export ARM_PRE=arm-linux-androideabi
export NDK=/home/myLib/android-ndk-r8b
export PATH=$PATH:/home/myLib/android-ndk-r8b
export NDK_PROJECT_PATH=/home/myLib/ndk1
Please help with your valuable suggestions!!

This is a very good tutorial for ndk beginners http://marakana.com/forums/android/examples/49.html
In tutorial : as you are building on android-ndk-r8b replace step which says
go to your NDK-HOME and run make APP=ndk_demo
do this
go to your android project directory and run ndk-build in terminal
Checklist
1) Make sure path NDK path is set
2) Make sure you generated the header file and moved to jni folder
3) You copied appropriate function signature from the header file to your c file this a place people make mistakes while referring to examples they blindly copy the function signature while using some other package name and class name.
JNIEXPORT jint JNICALL Java_com_your_package_class_method(JNIEnv *d, jobject e, jstring f);
4)Make file is present inside your jni folder and contains the correct c file name
5)You are running ndk-build in correct directory ,i.e., project home directory

try verbose with the "ndk-build".... So you can follow step-by-step what the build is doing with the instructions in the .mk
ndk-build -B V=1
use above for more details ....
