Build Android NDK development environment under OSX system

Gossip does not say much, direct into the topic:

My environment:

Operating system: OSX 10.10

Ide:eclipse Luna

Sdk:19

By default you've set up the SDK development environment

The first step is to download the NDK Toolkit under the OSX platform:

Compare the new R10 version in My network to download: Http://pan.baidu.com/s/1eQhn9aq

Second step, configure the environment variables

Create the. bash_profile file under your user directory to add:

Export path=${path}:/users/devnn/documents/android_ndk/android-ndk-r10ea_ndk_root=/users/devnn/documents/ Android_ndk/android-ndk-r10eexport A_ndk_rootexport path=${path}:/users/devnn/documents/android-sdk-macosx/ Platform-toolsexport path=${path}:/users/devnn/documents/android-sdk-macosx/toolsa_sdk_root=/users/devnn/ Documents/android-sdk-macosxexport A_sdk_root

Of course, note that the path should be modified accordingly.

Step three, open Eclipse config ndk path, preference->android->ndk

Fourth step, create test engineering ndk_test

Fifth step, right-click Project->android tools->add Support Library

Then create a directory in your project directory JNI contains a CPP file and a Mk file. We test the C file first, so we change its suffix to c. The content reference is as follows:

#include <string.h> #include <jni.h>jstring java_com_example_ndk_mainactivity_hello (jnienv* env, Jobject Thiz) {return (*env)->newstringutf (env, "Hello, this was from JNI");}

Note the name of the C file and the corresponding name in the Mk file should be the same.

Here, the C file code will error, see the next step.

Sixth step, right-click Project->propertiers->c/c++ gerneral->paths and Symbols

Click Add under the Include option, a dialog will pop up to let you select the header file path and choose File system, for example, my

/users/devnn/documents/android_ndk/android-ndk-r10e/platforms/android-19/arch-arm/usr/include

At this time, the errors in the C file will disappear.

package com.example.ndk;import android.app.activity;import  android.os.bundle;import android.widget.textview;public class mainactivity extends  activity {    private textview tvtext;    @ Override    protected void oncreate (bundle savedinstancestate)  {         super.oncreate (savedinstancestate);         setcontentview (R.layout.activity_main);         tvtext= (TextView)  findviewbyid (R.id.text);         tvtext.settext ( Hello ());     }    public native string hello ();     static{        system.loadlibrary ("NDK_TEST");     }} 

My engineering structure is as follows:

Then, run your project and you'll see the results.
