Use libgdx on Android

Use libgdx on Android

Libgdx is an excellent 2D/3D cross-platform physical engine. Today we will introduce how to use it on Android:

1.

In

2.

Decompress gdx-helloworld-0.9.2.zip, and thenImport GDX-helloworld directly in eclipse,Run as Java application directly, A dialog box is displayed,We can select helloworlddesktop., As follows:

Program:

Next we will introduce how to port to Android:

1.

Create an android project for libgdx as follows:

2.

Create a new libs folder under the root directory of the project, copy the armeabi and armeabi-v7a folders under libgdx to libs, and copy GDX. jar and gdx-backend-android.jar to libsThe result is as follows:

3.

Right-click the libgdx project, select properties, and click "add jars" in libraries of Java build path to addGDX. jar and gdx-backend-android.jar, As follows:

4.

Modify the libgdxactivity. Java file as follows:

package com.test.libgdx;import android.app.Activity;import android.os.Bundle;import com.badlogic.gdx.backends.android.AndroidApplication;public class LibgdxActivity extends AndroidApplication {    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                initialize(new FirstGame(), false);    }}

5.

Create a firstgame class, As follows:

Package COM. test. libgdx; 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 {/* spritebatch for plotting */private spritebatch batch; @ override public void create () {batch = new spritebatch (); // instantiate} @ 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); // clear screen 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 }}

6.

Run as Android Application in eclipse, as shown below:

Since we have not drawn any image, the result is a black screen, but at least the libgdx configuration is correct.

Done!
