我在 Android Studio 上构建了一个简单的应用程序,使用 Libgdx 来显示由 6 个 .png 图像组成的动画,我制作了一个 TextureAtlas。该项目构建良好,没有任何错误,但是当我尝试在模拟器中运行应用程序时,它在打开时崩溃。我知道这不是模拟器的错误,因为我已经使用相同的配置和库构建了一个应用程序来成功显示文本,而且这个应用程序也在我的 Galaxy Note 5 上崩溃。
这是核心 .java 文件的代码:
package com.mygdx.mytestgame;
import com.badlogic.gdx.ApplicationAdapter;
import com.badlogic.gdx.Gdx;
import com.badlogic.gdx.graphics.GL20;
import com.badlogic.gdx.graphics.g2d.SpriteBatch;
import com.badlogic.gdx.graphics.g2d.Animation;
import com.badlogic.gdx.graphics.g2d.TextureAtlas;
import com.badlogic.gdx.graphics.g2d.TextureRegion;
public class MyTestGame extends ApplicationAdapter {
private SpriteBatch batch;
private TextureAtlas shooterAtlas;
private Animation<TextureRegion> animation;
private float timePassed = 0;
@Override
public void create () {
batch = new SpriteBatch();
shooterAtlas = new TextureAtlas(Gdx.files.internal("shooter.atlas"));
animation = new Animation<TextureRegion>(1/30f, shooterAtlas.getRegions());
}
@Override
public void dispose() {
batch.dispose();
shooterAtlas.dispose();
}
@Override
public void render () {
Gdx.gl.glClearColor(0,1,0,1);
Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
batch.begin();
timePassed += Gdx.graphics.getDeltaTime();
batch.draw(animation.getKeyFrame(timePassed, true), 300, 500);
batch.end();
}
}
这是 Android 清单文件:
<?xml version="1.0" encoding="utf-8"?>
<uses-sdk android:minSdkVersion="9" android:targetSdkVersion="26" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
这是 logcat 上显示的崩溃:

它说读取文件“shooter.atlas”时出错,这是我用于动画的TextureAtlas。此文件名正确,位于C:\Users\user\Documents\libGDX Projects\android\assets
解决方案是什么?
