我们正在开发一个使用 GCM 的应用程序。它在大多数手机上运行良好,但是,我们有两部手机(galaxy note 2 和 galaxy s plus)收不到消息。或者可能只是广播接收器未被调用。
服务端推送:
$data = array(
'data' => array('message' => $messageData),
'delay_while_idle' => false,
'type' => 'New',
'flag' => 1,
'registration_ids' => $registrationIdsArray
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_URL, "https://android.googleapis.com/gcm/send");
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 1);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
$response = curl_exec($ch);
curl_close($ch);
发送推送时的响应接收者:
{
"multicast_id":4735518740307255391,
"success":4,
"failure":0,
"canonical_ids":0,

我们已经尝试了几乎所有方法,但似乎没有任何效果。 galaxy note 2 运行 4.3 没有谷歌帐户和 wifi。 Galaxy s plus 运行 android 2.3.5 并在 wifi 上使用谷歌帐户。
我们了解到某些 wifi 上的设备无法接收 GCM,因此我们尝试重启手机但没有任何反应。
提前感谢您提供任何线索或答案!

最佳答案
你的广播接收器中的类别是错误的:
<receiver
android:name="com.innocreate.app.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.app.muf_appen" />
</intent-filter>
</receiver>
它应该是你的应用程序的包名,com.innocreate.app
,而不是com.app.muf_appen
。
这通常只会在较旧的 Android 版本中导致问题。
关于android - 尽管所有消息都从服务器成功发送,但某些设备未收到 GCM 推送,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/21409143/
