Ç的Andr​​oid NDK再利用$ C $ [英] Re-use code Android NDK

问题描述

我发现很多教程展示如何开始开发使用NDK Android应用程序。

I found a lot of tutorials showing how to start developing Android Applications using NDK.

不过，我有一个相当简单/愚蠢的问题：

But I have a rather "easy/stupid" question:

请考虑以下两个教程：

1. http://mobile.tutsplus.com/tutorials/android/ndk-tutorial /
2. <一个href="http://www.indiedb.com/tutorials/creating-compiling-and-deploying-native-projects-from-the-android-ndk" rel="nofollow">http://www.indiedb.com/tutorials/creating-compiling-and-deploying-native-projects-from-the-android-ndk
3. http://mindtherobot.com/blog / 452 / android的初学者，NDK，安装一步一步/

现在，在第二个教程，他们正在建设的 HELLO-JNI 的例子。

Now, in the second tutorial they are building the hello-jni example.

我的问题是：

使用后的 NDK建造

和产区的：

是它可能使用结果 libhello-jni.so 和分发本给别人，而不是实际 C code？

is it possible to use the resulted libhello-jni.so and distribute this to others instead of the actual C code?

例如修改 Android.mk 和替换 com_myproject_MyActivity.c 到的东西。所以以包括共享库：

For example modifying the Android.mk and replacing com_myproject_MyActivity.c to something.so in order to include the shared library?:

LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := mylib
LOCAL_SRC_FILES := com_myproject_MyActivity.c
include $(BUILD_SHARED_LIBRARY)

任何建议或教程欢迎。先谢谢了。

Any suggestions or tutorials welcome. Thanks in advance.

推荐答案

您可以通过复制到库/ armeabi 使用prebuilt NDK库（或任何架构是它），然后装在运行时。从Android构建系统的角度来看，它只是一个文件中的APK包含。

You can use a prebuilt NDK library by copying it into libs/armeabi (or whatever architecture is it for), then loading in run-time. From the standpoint of the Android build system, it's just another file to include in the APK.

但问题是，JNI函数名称包括，​​按照惯例，包和类的名称，他们将属于;因此从SO消费项目的角度来看，它的使用将看起来相当不自然，因为没有任何的JNI功能将融入它的类。你可能要发布一个同伴JAR其中相应的Java类中声明。

The problem, however, is that the JNI function names include, by convention, the name of the package and class they will belong to; so from the standpoint of a SO consumer project, its use will look rather unnatural, as none of the JNI functions would fit into its classes. You'll probably have to ship a companion JAR where the respective Java classes are declared.
