和我的Android.mk

LOCAL_PATH:= $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE    := Hello
LOCAL_CFLAGS    := -Werror
LOCAL_SRC_FILES := lib.c


include $(BUILD_SHARED_LIBRARY)

and my Application.mk
APP_PROJECT_PATH := D:/Java_2/workspace_indigo/JniTest

像在文档中说的那样简单，但仍然不起作用.. 为什么它不能正常运作的原因是什么？

Answer 1

显然，您的Android.mk文件位于错误的位置，因为它的当前位置是：

native/Android.mk

并且您的构建脚本希望它在

中

src/jni/Android.mk

您必须更改脚本或复制/移动文件。

“您的APP_BUILD_SCRIPT指向一个未知文件：./ jni / Android.mk”
