java - 谷歌地图 android API V2 失败

Question

尝试将 map 添加到 Android 应用程序中时，我已经创建了 API key 并启用了 Google Map Android V2；我在 list 文件中添加了权限、google play 服务版本和 API key 。我还在项目中添加了 Google Play 服务库。

但是当我启动应用程序时它停止了，我不知道为什么，我认为这与权限有关，但为了确保，我按照 Google Developpers 网站的建议复制/粘贴了权限向我们展示如何添加 map 。但正如我所说，我不确定这是否是真正的交易。这是我的代码:

list 文件:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="usthb.appusthb"

    </application>

</manifest>

主要布局:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:name="com.google.android.gms.maps.MapFragment"/>

主要 Activity :

public class MainActivity extends FragmentActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Toast.makeText(this, "sup", 2000).show();
    }
}

Answer 1

改变这个

 android:name="com.google.android.gms.maps.MapFragment"/>

到

 android:name="com.google.android.gms.maps.SupportMapFragment"/>

因为你的min sdk是11，所以你需要使用SupportMapFragment。对于 12 及以上使用 MapFragment。
