我无法编译这段代码，因为它说：
PlusClient.Builder 无法解析为类型
在
mPlusClient = new PlusClient.Builder(this, this, this)
.setVisibleActivities( "http://schemas.google.com/AddActivity",
"http://schemas.google.com/BuyActivity").build();
也在onConnected()
我null得到accountName
String accountName = mPlusClient.getAccountName();
