从库项目中注册GCM

Question

我正在尝试从库项目注册到GCM, GCMIntentService在库项目中定义。

这是我的注册码(在图书馆项目中):

public static void init(Context context, String id){
    GCMRegistrar.checkDevice(context);
    GCMRegistrar.checkManifest(context);
    GCMRegistrar.register(context, id);
}

但是GCMIntentService的回调函数没有被调用，它们只在我将库项目作为独立的android项目运行时被调用。

下面是我的测试项目清单:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.pushtest"
    android:versionCode="1"
    android:versionName="1.0" >
    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="17" />
    <permission
        android:name="com.example.pushtest.permission.C2D_MESSAGE"
        android:protectionLevel="signature" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.VIBRATE" />
    <!-- GCM requires a Google account. -->
    <uses-permission android:name="android.permission.GET_ACCOUNTS" />
    <uses-permission android:name="android.permission.WAKE_LOCK" />
    <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" />
    <uses-permission android:name="com.example.pushtest.permission.C2D_MESSAGE" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
        android:name=".PushTestApp" >
        <activity
            android:name="com.example.pushtest.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <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.pushtest" />
            </intent-filter>
        </receiver>
    </application>
    //push library definition
    <service android:name="com.test.pushlibrary.GCMIntentService" />
</manifest>

你必须这样做:

写一个类(在你的库项目中)覆盖GCMBroadcastReceiver:

package com.test.pushlibrary;
import android.content.Context;
import com.google.android.gcm.GCMBroadcastReceiver;

public class PushLibraryBroadcastReceiver extends GCMBroadcastReceiver
{
    /**
     * Gets the class name of the intent service that will handle GCM messages.
     */
    @Override
    protected String getGCMIntentServiceClassName(Context context) {
        return "com.test.pushlibrary.GCMIntentService";
    }
}

更改舱单以引用新的接收器:

    <receiver
        android:name="com.test.pushlibrary.PushLibraryBroadcastReceiver"
        ...

你的原始代码没有工作的原因是getGCMIntentServiceClassName的默认实现假设意图服务类位于应用程序的包中，所以它期望com.example.pushtest.GCMIntentService而不是com.test.pushlibrary.GCMIntentService。
