我可以在我的启动界面注册C2DM(推送通知)吗?

Question

是否可以在我的启动画面中注册C2DM ?

import android.app.Activity;
import android.app.PendingIntent;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class myMain extends Activity {
/** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.isplash);
    MediaPlayer mpSplash = MediaPlayer.create(this, R.raw.musicsplash);
    mpSplash.start();
    Intent registrationIntent = new Intent("com.google.android.c2dm.intent.REGISTER");
    registrationIntent.putExtra("app", PendingIntent.getBroadcast(this, 0, new Intent(), 0));
    registrationIntent.putExtra("sender", "my email address");
    startService(registrationIntent);
    Thread logoTimer = new Thread(){
        public void run(){
            try{
                sleep(4000);
                startActivity(new Intent("com.ishop.pizzaoven.CLEARSCREEN"));
            } catch (InterruptedException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
              finally{
                finish();
            }
        }
    };
    logoTimer.start(); 
}
@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
}
@Override
protected void onResume() {
    // TODO Auto-generated method stub
    super.onResume();
}
@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
}
@Override
protected void onStop() {
    // TODO Auto-generated method stub
    super.onStop();
}

}

是。你可以在任何你喜欢的地方注册C2DM，而且通常越快越好，所以应用程序已经准备好接收信息了。注意，你不需要每次应用程序运行时都重新注册，注册一次，将其存储到pref中，只有在pref为空时才再次注册(例如在卸载/重新安装后)
