这是我的android启动器类:
Here is my android launcher class:
package com.spaceshooter.game;
import android.os.Bundle;
import com.badlogic.gdx.backends.android.AndroidApplication;
import com.badlogic.gdx.backends.android.AndroidApplicationConfiguration;
import com.spencergang.game.SSGame;
public class AndroidLauncher extends AndroidApplication {
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
config.useAccelerometer = true;
config.useCompass = true;
initialize(new SSGame(), config);
}
}
以下是屏幕截图:
推荐答案
我在Android平板电脑上卸载了该应用程序，然后清理了该项目.现在我解决了问题使用引导类加载器找不到类；没有可用的堆栈跟踪"就像你一样.
I uninstall The application on the Android pad,then clean the project.and now I solve the problem"Class not found using the boot class loader; no stack trace available"just like you.
