GCM在4.0.4之前的设备上注册但无法接收消息

Question

如果可能的话，请帮助我解决问题。我一直在尝试实现基本的GCM设置。服务器端我使用了来自这里顶部答案的PHP代码 - GCM with PHP (Google Cloud Messaging)，客户端则遵循了Google的GCM教程。在我的Nexus 4上整个过程都运作正常，但是我尝试过的两个低于Android 4.0.4版本的设备无法使用。一个是运行4.0.3的htc one v，另一个是运行2.3.4的sony ericsson。这可能与低于4.0.4版本的设备有关，但它们成功注册并正确地给出了RegIds。它们只是无法接收任何信息，即使GCM服务器已经接收到并发送了成功的消息id，甚至广播接收器也不会启动。如果您知道为什么会发生这种情况，可以帮忙解决吗？顺便说一下，这两个设备都已经注册了谷歌账户。

这是我的清单文件。

以下是php实现代码。目前它正在使用静态regid..我通过从应用程序中转储它们来获取这些信息。我认为它工作得很好，因为我在我的nexus 4上能够正常接收消息。执行此操作将给我三个message ids。

<?php

// Replace with real BROWSER API key from Google APIs
$apiKey = "myapikey";

// Replace with real client registration IDs 
$registrationIDs = array(  "regid1", "regid2" , "regid3" );


// Message to be sent
$message = "Hello";

// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';



$fields = array(
                'registration_ids'  => $registrationIDs,
                'data'              => array( "message" => $message ),
                );

$headers = array( 
                    'Authorization: key=' . $apiKey,
                    'Content-Type: application/json'
                );
// Open connection
$ch = curl_init();
echo "here";
// Set the url, number of POST vars, POST data
curl_setopt( $ch, CURLOPT_URL, $url );

curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );

curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode( $fields ) );
// Execute post
$result = curl_exec($ch);
curl_close($ch);

if(curl_errno($ch)){ echo 'Curl error: ' . curl_error($ch);}
echo $result;

?>

这是广播接收器。在这两个设备中，此代码未被调用，因为日志未显示任何内容。

        ComponentName comp = new ComponentName(context.getPackageName(),
                GcmIntentService.class.getName());

你的清单包名是“com.gole.firstgcm”。我假设你正在广播接收器中使用相同的包名，或者你正在使用“my.package.name”？ - drulabs

请放置您的PHP部分以及应用程序代码！ - Saqib

是的，对不起。我仅仅为了提出问题而改了那个，忘记在某些地方改回去了。请忽略那个，很抱歉。它不能和真实的包名一起工作。我会加上PHP和Java代码的。 - Adun Toridas

有什么新消息吗？我也遇到了同样的问题。 - Daniel L.

Answer 1

尝试用com.gole.firstgcm替换my.package.name

- maslakoff

是的，对不起。我只是为了提问而更改了那个。忘记在某些地方进行更改了。请忽略那个，抱歉。它与真实的包名称不兼容。 - Adun Toridas
