Andriod源码开发,打包so到apk(3)

    return add22(x,y);
}
e)        在工程根目录下输入mm,编译提示out/target/product/sk886x/obj/STATIC_LIBRARIES /libtestapi_intermediates/libtestapi.a 找不到,这时候我们把b)得到的libtestapi.a放到提示的文件夹里,再重新编译就通过.得到的apk,安装到目标机,运行,成功.
4.        在步骤3的基础上,我们让callapp.c调用libtesapi.so
a)        修改工程根目录,android.mk
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := user eng
LOCAL_SRC_FILES := $(call all-subdir-java-files)
LOCAL_PACKAGE_NAME := jnitest
LOCAL_JNI_SHARED_LIBRARIES := libapptest libtestapi
include $(BUILD_PACKAGE)
include $(LOCAL_PATH)/jni/Android.mk
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))注意libapptest libtestapi 要同一行,否则,前面一个不会打包到apk里.
b)        Jni目录下Android.mk 里添加
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE_TAGS := user eng
LOCAL_MODULE    := libapptest
LOCAL_SRC_FILES := callapp.c
LOCAL_C_INCLUDES += \
        $(JNI_H_INCLUDE)
LOCAL_SHARED_LIBRARIES := libutils libtestapi
#LOCAL_STATIC_LIBRARIES := libtestapi
LOCAL_LDLIBS := -ldl -llog
LOCAL_PRELINK_MODULE := false
include $(BUILD_SHARED_LIBRARY)               
c)        编译,提示找不到libtestapi.so,我们把他分别复制到out/target/product/sk886x/obj/lib/和/out/target/product/sk886x/system/lib/ 这样能编译通过.
d)        运行apk,发现提示错误.由于libtestapi.so 是我们以动态共享库提供给libapptest.so,所以libtestapi.so要放到/system/lib里,通过adb push 到/system/lib以后,重新运行apk,可以正确运行.
