Question

我正在尝试实施GCM。

我实施了谷歌规定的全部内容。当我注册设备时，接收器中的回调没有任何影响。 GCMIntentService类中甚至没有onError（）。

从不构造GCMIntentService。

这是我的代码......

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.roconmachine.gcm"
      android:versionCode="1"
      android:versionName="1.0">
    <uses-sdk android:minSdkVersion="8"/>

    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>

    <permission android:name="com.roconmachine.gcm.permission.C2D_MESSAGE" android:protectionLevel="signature" />
    <uses-permission android:name="com.roconmachine.gcm.permission.C2D_MESSAGE" /> 

    <!-- App receives GCM messages. -->
    <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/icon" android:label="@string/app_name">
        <activity android:name=".NewGCMActivity"
                  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" />

          </intent-filter>
        </receiver>

        <service android:name=".services.GCMIntentService" android:enabled="true"/>
    </application>
</manifest>

Answer 1

确定。通过鸟瞰图没有特定的错误。你能尝试一件傻事吗？您已将GCMIntentService放入服务包中。你可以把它保存在主包中并测试一次。

Answer 2

您需要将类别添加到接收器

<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.roconmachine.gcm" />
      </intent-filter>
    </receiver>

此外，您必须将服务移至应用程序包，文档说：

此意向服务将由GCMBroadcastReceiver（由GCM库提供）调用，如下一步所示。它必须是com.google.android.gcm.GCMBaseIntentService的子类，必须包含公共构造函数，并且应该命名为my_app_package.GCMIntentService（除非您使用GCMBroadcastReceiver的子类来覆盖用于命名服务的方法）
