My .so File Info:
"libvcsFPClient.so: ELF 32-bit LSB shared object, ARM, version 1 (SYSV), dynamically linked, not stripped."
So it was build in above environment.
Now problem is , while running the project it gives the following error log:

My Android.mk file:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := hello-jni
LOCAL_SRC_FILES := hello-jni.c
include $(BUILD_SHARED_LIBRARY)
include $(CLEAR_VARS)

How to link prebuilt cross compiler toolchain?
How to modify further .mk file ?
My system Properties are ,
