Question

当我在Galaxy S3中运行时，出现了Google的名称和+/-缩放，但地图永远不会出现，请有人帮帮我！

我已经完成了三次所有步骤来生成API密钥。

我不知道我是否必须在Activity中执行某些操作，但我的活动扩展了FragmentActivity，但我总是尝试获取此地图，始终返回null ...

GoogleMap mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)).getMap();

我的清单：

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="21" />

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

        android:value="xxxxxxxxxxxx" />

我的activity_main.xml
