我正在尝试获取设备的注册 ID(使用模拟器进行测试)以使用 GCM 设置推送通知。
我尝试了以下代码,这给了我以下错误:
Unable to start service Intent { act=com.google.android.c2dm.intent.REGISTRATION (has extras) } U=0: not found

我正在使用 BroadcastReceiver 来达到目的:
package com.me.pushnotifications;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class MyBroadcastReceiver extends BroadcastReceiver{
@Override
public void onReceive(Context arg0, Intent intent) {
// TODO Auto-generated method stub
String action = intent.getAction();
Log.i("action::",action);
try{
if(action.equals("com.google.android.c2dm.intent.REGISTRATION")){
String regId = intent.getStringExtra("registration_id");
String error = intent.getStringExtra("error");
String unregistered = intent.getStringExtra("unregistered");
Log.i("regId::",regId);
}
else if(action.equals("com.google.android.c2dm.intent.RECEIVE")){
String data = intent.getStringExtra("data");
Log.i("data::",data);
}
}
finally{
}
}
}
主要活动
package com.me.pushnotifications;
import android.app.Activity;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final Context context = getApplicationContext();
final String appId = getResources().getString(R.string.appId) ;
Log.i("appName::",appId);
Button activateButton,deactivateButton;
activateButton = (Button)findViewById(R.id.activateButton);
deactivateButton = (Button)findViewById(R.id.deactivateButton);
activateButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.i("activate::","clicked");
Intent regIntent = new Intent("com.google.android.c2dm.intent.REGISTRATION");
Log.i("intent::","created");
regIntent.putExtra("app", PendingIntent.getBroadcast(context, 0,
new Intent(), 0));
regIntent.putExtra("sender", "registration_id");
startService(regIntent);
}
});
deactivateButton.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Log.i("deactivate::","clicked");
Intent unregIntent = new Intent("com.google.android.c2dm.intent.UNREGISTER");
Log.i("intent::","created");
unregIntent.putExtra("app", PendingIntent.getBroadcast(context, 0,
new Intent(), 0));
startService(unregIntent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
我已经为 API 级别 18 安装了 Google API。问题的原因可能是什么?
