我对这个问题困惑了很多天。当我在模拟器 4.2.2 api 17 上运行它时,它显示:除非您更新 Google Play 服务,否则该应用程序不会运行。
我不知道该怎么做。我的代码列出:

活性: package com.example.demogooglemap

import android.os.Bundle;
import android.app.Activity;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
我还导入了 google-play-services_lib。
