Android 谷歌地图版本2不适用于片段

我不知道，我在装载映射版本2的清单、活动或xml中做错了什么

我发现了多个例外如果你看到我的简明日志

您需要将以下内容添加到清单文件中

 <meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version" />

将其放在清单的末尾，映射API键元数据标记之后

退房

这是从google play services上一次13版更新中添加的新要求。

您需要在清单中添加以下内容

 ...
    <meta-data android:name="com.google.android.gms.version"  
    android:value="@integer/google_play_services_version" />

</application>

。。。

此信息可在logcat错误消息中找到

也在网站上

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

    try {
        // Loading map
        initilizeMap();

    } catch (Exception e) {
        e.printStackTrace();
    }

}

/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(
                R.id.map)).getMap();

        // check if map is created successfully or not
        if (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }
}

 <meta-data android:name="com.google.android.gms.version"
   android:value="@integer/google_play_services_version" />

 ...
    <meta-data android:name="com.google.android.gms.version"  
    android:value="@integer/google_play_services_version" />
