Android CCS GCM注册

Question

我是GCM和CCS的新手。我通过引用this link使用PHP设置了GCM。

现在我正在尝试从HTTP跳转到CCS，但我无法注册CCS。

这是我的代码：

import java.io.IOException;
import java.util.concurrent.atomic.AtomicInteger;

import android.content.Context;
import android.content.SharedPreferences;
import android.content.pm.PackageInfo;
