如何建立一个本地（命令行）执行在Android上运行吗？ [英] How do I build a native (command line) executable to run on Android?

问题描述

我已经受够了建立一个Android应用程序（GUI）的成功，采用的是原生（JNI）库。

I've had success with building an Android app (GUI) that uses a native (JNI) library.

不过，现在我想创建一个运行在命令行（root权限），不使用图形用户界面在所有的可执行文件。如何建立类似的东西？

However, now I would like to create an executable that runs from the command line (root privileges) and does not use a GUI at all. How do I build something like that?

推荐答案

随着NDK r8d的，这可以在一个更简单的方法解决了。

As of NDK r8d, this can be solved in a much simpler way.

1. 创建与下面的目录层次结构中的项目：

1. Create a project with the following directory hierarchy:

project/
    jni/
        Android.mk
        Application.mk
        *.c, *.cpp, *.h, etc.

在Android.mk中填写以下内容。最重要的是最后一行。检查NDK的文档的其他变量的含义。

Fill in Android.mk with the following content. The most important thing is the last line. Check the NDK doc for the meaning of the other variables.

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := name-of-your-executable
LOCAL_SRC_FILES := a.cpp b.cpp c.cpp etc.cpp
LOCAL_CPPFLAGS := -std=gnu++0x -Wall         # whatever g++ flags you like
LOCAL_LDLIBS := -L$(SYSROOT)/usr/lib -llog   # whatever ld flags you like

include $(BUILD_EXECUTABLE)    # <-- Use this to build an executable.

转到项目/ 目录，只需键入

Go to the project/ directory, and simply type

ndk-build

结果将被放置在项目/库/＆LT;弓＆GT; /名称中，您可执行
