新建一个Android项目，File -> New -> Project -> Android Project。我选的SDK是1.6的，最低选择应该是1.5.
新建一个文件夹libs（这个名字是固定的，不能随意改），将下载到的jar复制进去，android平台只需要复制gdx.jar和gdx-backend-android.jar。
增加引用，然后将armeabi和armeabi-v7a两个文件夹复制到libs文件夹中。
然后写个小东西测试一下环境有没有问题。风之境地
新建类HelloGameActivity，继承AndroidApplication类。
package com.cnblogs.htynkn;
import com.badlogic.gdx.backends.android.AndroidApplication;
import android.os.Bundle;
public class HelloGameActivity extends AndroidApplication {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
initialize(new FirstGame(), false);
}
}
initialize(new FirstGame(), false);
就是启动游戏的关键，FirstGame是一个实现了ApplicationListener的类。
代码如下
package com.cnblogs.htynkn;
import com.badlogic.gdx.ApplicationListener;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL10;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
public class FirstGame implements ApplicationListener {
//绘图用的SpriteBatch
private SpriteBatch batch;
@Override
public void create() {
batch = new SpriteBatch(); //实例化
}
@Override
public void dispose() {
// TODO Auto-generated method stub
}
@Override
public void pause() {
// TODO Auto-generated method stub
}
@Override
public void render() {
Gdx.gl.glClear(GL10.GL_COLOR_BUFFER_BIT); //清屏
batch.begin();
batch.end();
}
@Override
public void resize(int width, int height) {
// TODO Auto-generated method stub
}
@Override
public void resume() {
// TODO Auto-generated method stub
}
}
环境搭建就说到这里，下一篇是关于图片绘制的。
注意：
如果仔细观察Logcat，就会发现一个error：
E/libEGL(382): couldn't load <libhgl.so> library (Cannot load library: load_library[984]: Library 'libhgl.so' not found)
这个没什么关系，这是系统尝试加载硬件OpenGL驱动失败了，然后回到软件的处理方法上，不是缺陷或者错误。
