[Saba Arshad]

Hello Sir,

>From many days i am trying to add strace in my application and call it at
run time. for this purpose i have installed ndk, imported strace package
through Android.mk file.

My Android.mk file is:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

*include $(BUILD_SHARED_LIBRARY)*


I cannot find any documentation about *BUILD_SHARED_LIBRARY* at
official page (https://developer.android.com/ndk/guides/android_mk.html).

I cannot find any way of calling the strace executable in java class,
as for shared library we can use System.loadlibrary(strace).

Can anyone suggest me the solution?

Thanks in advance.
