我在我的手机上使用了我的应用程序（三星Galaxy S3,4.1.2），因为人们建议我使用Android地图v2应用程序，但我仍然得到同样的错误，它说我的应用程序已经不幸地停止了。

MainActivity.java 

package com.example.name;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        SupportMapFragment fragment = new SupportMapFragment();
        getSupportFragmentManager().beginTransaction()
                .add(android.R.id.content, fragment).commit();
    }
}

的Manifest.xml

3 个答案:

答案 0 :(得分：0)

不知何故，您缺少项目中Maps V2库的代码。您需要正确附加到代表Play服务SDK的Android库项目。请参阅the Play Services documentation，特别是以“设置项目以使用Google Play服务SDK”开头的部分。

答案 1 :(得分：0)

当我将 Google_Play_Services_lib 导入eclipse而未选中将项目复制到工作区的选项时出现此错误。请参阅图片 enter image description here

同时检查我的blogPost我试图解释问题

答案 2 :(得分：0)

如果您使用的是Google I / O之后的SDK工具v17，请在此处检查是否有任何帮助：
