我刚开始学习安卓。我整天都在尝试在 Android 上使用谷歌地图，但每次我在模拟器上运行它时，它都会发出“不幸的是，已停止”的通知。这是我的代码： 1. 清单：

活动主.xml：

MainActivity.java：

package com.example.mapmapmap;
import android.os.Bundle;
import android.app.Activity;

public class MainActivity extends Activity {

@Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    }
}

您的错误表明您手动修改了项目的构建路径以引用 JAR。那将代表两个错误：

  1. 永远不要手动修改标准 Android 应用项目的构建路径

  2. Play Services SDK 是一个 Android 库项目，而不仅仅是一个 JAR

可以在Play Services SDK 文档中找到将 Play Services SDK 附加到您的项目的说明。
