This makefile shows how to build a shared library and an activity that

bundles the shared library and calls it using JNI.

TOP_LOCAL_PATH:= $(call my-dir)

Build activity

LOCAL_PATH:= $(TOP_LOCAL_PATH) include $(CLEAR_VARS) LOCAL_MODULE_TAGS := samples LOCAL_SRC_FILES := $(call all-subdir-java-files) LOCAL_PACKAGE_NAME := SimpleJNI LOCAL_JNI_SHARED_LIBRARIES := libsimplejni LOCAL_PROGUARD_ENABLED := disabled LOCAL_SDK_VERSION := current include $(BUILD_PACKAGE)

============================================================

Also build all of the sub-targets under this one: the shared library.

include $(call all-makefiles-under,$(LOCAL_PATH))
