【问题描述】：

我有几个关于 GCM（Google 云消息传递）的问题。

第一个问题是：我无法启动程序。它似乎总是崩溃：

清单：

 <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.gcmtutorial"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />

    <permission android:name="com.example.gcmtutorial.permission.C2D_MESSAGE" android:protectionLevel="signature" />
<uses-permission android:name="com.example.gcmtutorial.permission.C2D_MESSAGE" /> 
<uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
<!-- GCM connects to Google Services. -->
<uses-permission android:name="android.permission.INTERNET" /> 
<!-- GCM requires a Google account. -->
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<!-- Keeps the processor from sleeping when a message is received. -->
<uses-permission android:name="android.permission.WAKE_LOCK" />

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

          <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" >
              <intent-filter>
                <action android:name="com.google.android.c2dm.intent.RECEIVE" />
                <action android:name="com.google.android.c2dm.intent.REGISTRATION" />
                <category android:name="com.example.gcmtutorial" />
              </intent-filter>
            </receiver>

        <service android:name=".GCMIntentService" />
        <activity
            android:name=".MainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

    </application>

</manifest>

代码是：

package com.example.gcmtutorial;

import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;

import com.google.android.gcm.GCMRegistrar;

public class MainActivity extends Activity 

    @Override
    public void onCreate(Bundle savedInstanceState) 
        super.onCreate(savedInstanceState);
        GCMRegistrar.checkDevice(this);
        GCMRegistrar.checkManifest(this);

        final String regId = GCMRegistrar.getRegistrationId(this);
        if (regId.equals("")) 
          GCMRegistrar.register(this, "714669202278");
         else 
          Log.v("Registered", "Already registered");
        

        setContentView(R.layout.activity_main);
    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) 
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    

我收到的错误是

我已经谷歌了，但似乎没有解决方案。

我的第二个问题是： 如何使用 GCM 编写 php 服务器 我提到过： GCM sending with curl (php) GCM with PHP (Google Cloud Messaging)

我不明白的是注册 ID 是什么意思

【问题讨论】：

您的清单看起来不错。您是否尝试卸载该应用，然后重新安装？

【参考方案1】：

在您的清单中尝试使用 package.GCMIntentService
