我也想知道最低要求谷歌地圖API第2

Answer 1

首先安裝谷歌播放服務，如果你是使用Android 2.2，然後使用此代碼

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(); 
    }  
    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.activity_main, menu); 
     return true; 
    } 
} 

Answer 2

你應該嘗試導入谷歌播放庫中this guide

Answer 3

我遇到了類似的問題，我通過以下方案步驟解決了該問題：

-1-我下載了最新的ADT（Windows 64位版本23.0.3）以安裝Google Play服務API。

-2-問題依然存在，試用@ user3469294在這個link回答。

也有一些是錯誤的ADT 64位版本，當涉及到使用它的SDK的SupportMapFragment（不斷崩潰），下載ADT爲32位和安裝谷歌播放服務的API，然後使用它的圖書館解決我的問題。
