Question

我正在尝试使用GCM服务向我的设备发送推送通知。

我已经关注服务器端函数Android Hive tutorial（现在已经不再使用many other questions and answers了），服务器端函数看起来按预期工作，因为我可以得到这种输出：< / p>

{"multicast_id":9131068334342174816,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1377441098827443%1d84a26ff9fd7ecd"}]}

但根据some answers，接收此响应只意味着GCM服务器已接受该消息进行发送，但并未发送该消息。因此，正如预期的那样，我的BroadcastReceiver没有收到任何内容。

这是我的BroadcastReceiver代码：

public class GcmBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i("gcm_debug", "PushReceiver onReceive called");

        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(context);

        String msgType = gcm.getMessageType(intent);

        if(!extras.isEmpty()){
            if(GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR.equals(msgType)){
                Log.i("gcm_debug", "Message send error");
            }else if(GoogleCloudMessaging.MESSAGE_TYPE_DELETED.equals(msgType)){
                Log.i("gcm_debug", "Message deleted");
            }else if(GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(msgType)){
                Log.i("gcm_debug", "Message received : " + extras.toString());
            }
        }

        setResultCode(Activity.RESULT_OK);
    }

}

我的AndroidManifest：

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />

<!-- Because this app is using the GCM library to send messages, the min SDK cannot be lower

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="18" />


<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/LovRTheme" >
    <receiver
        android:name=".GcmBroadcastReceiver"
        android:permission="com.google.android.gcm.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="<MYAPP>" />
        </intent-filter>
    </receiver>
    <service android:name=".GcmIntentService" />

服务器端代码：

    $url = "https://android.googleapis.com/gcm/send";
    $fields = array(
        'registration_ids' => array($dstRegId),
        'delay_while_idle' => true,
        'data' => array("message" => $message));

    $headers = array(
        'Authorization: key=' . $google_api_key,
        'Content-Type: application/json');

    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));

    $result = curl_exec($ch);
    if($result === FALSE){
        die("Curl failed");
    }
    curl_close($ch);

    echo $result;

我在家编码，因此我认为GCM不会有进出网络的问题，因为GCM使用了一种反向shell连接。无论如何，我没有收到任何我期待的日志输出。

修改在我的应用程序运行一段时间后，LogCat向我发送了以下输出：

Answer 1

这是您的错误：

<receiver
    android:name=".GcmBroadcastReceiver"
    android:permission="com.google.android.gcm.c2dm.permission.SEND" >

应该是：

<receiver
    android:name=".GcmBroadcastReceiver"
    android:permission="com.google.android.c2dm.permission.SEND" >

Android GCM消息已成功发送但未收到
