我有c2dm的注册ID和身份验证令牌。然后我将这些值存储在db中。并使用PHP，我可以发送一条消息给c2dm服务器。但我的问题是我不知道如何在应用程序中接收消息。我不确定我获取信息的方式是否正确。无论如何，我将在下面给出它。
我有一个活动使用注册意图注册到c2dm。和一个接收器接收reg_id和通知消息。它正在注册c2dm而不是接收消息。
<intent-filter>
<action android:name="com.google.android.c2dm.intent.REGISTRATION"></action>
<category android:name="my.android.c2dm"></category>
</intent-filter>
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE"></action>
<category android:name="my.android.c2dm"></category>
</intent-filter>
</receiver>
</application>
Intent objRegIntnet=new Intent("com.google.android.c2dm.intent.REGISTER");
objRegIntnet.putExtra("app",PendingIntent.getBroadcast(this,0,new Intent(),0));
objRegIntnet.putExtra("sender","mymail@gmail.com");
startService(objRegIntnet);
public class c2dmReceiver extends BroadcastReceiver
{
private static String KEY = "c2dmPref";
private static String REGISTRATION_KEY = "registrationKey";
private Context context;
@Override
public void onReceive(Context context, Intent intent)
{
this.context = context;
if (intent.getAction().equals("com.google.android.c2dm.intent.REGISTRATION"))
{
handleRegistration(context, intent);
}
else if (intent.getAction().equals("com.google.android.c2dm.intent.RECEIVE"))
{
handleMessage(context, intent);
}
}
private void handleRegistration(Context context, Intent intent)
{
//handles registeration
}
private void handleMessage(Context context, Intent intent)
{
String title= intent.getStringExtra("title");
String message= intent.getStringExtra("msg");
Toast.makeText(context,"title : "+title+"\n message : "+message,1).show();
//Do whatever you want with the message
}
请告诉我我做错了什么......
大家好，今天同样的代码对我来说很烦人。我做的错误是使用PHP代码。如果将值传递给POST，我将其发送为GET。当我将其更改为POST时，将显示toast消息。但是还有一些问题。
此处的标题和msg值为null。 我的PHP代码是：
function sendMessageToPhone($authCode, $deviceRegistrationId, $msgType, $messageText)
{
//$messageText="have a nice day";
//$msgtype="important";
$headers = array('Authorization: GoogleLogin auth=' . $authCode);
$data = array(
'registration_id' => $deviceRegistrationId,
'collapse_key' => $msgType,
'data.message' => $messageText
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://android.apis.google.com/c2dm/send");
if ($headers)
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
实际上我不确定应该为collapse_key和data.message变量使用什么类型的值。
请帮帮我... 谢谢......
答案 0 :(得分：3)
最后我找到了给出collapse_key和数据的方法.. collapse_key应该是一个字符串，它是一组消息的名称或一种特定类型的消息。如果我们使用相同的collapse_key发送多条消息，则最新消息将从c2dm服务器发送到设备。
示例：$ collapse_key =“important”;
和数据。是重要的事情。这将包含我们要发送的消息。
例如：如果我们想发送消息“祝你有个美好的一天”，那么我应该给它一个关键名称。 data。=“祝你有愉快的一天”; 这里'愿望'是关键。在接收器中，我应该使用相同的密钥名称来检索消息。
private void handleMessage(Context context, Intent intent)
{
String mywish= intent.getStringExtra("wishes");
Toast.makeText(context,"my wishes : "+mywish,1).show();
}
对所有人抱歉..

这是我的代码我用它来接收C2DM服务器的通知表格，它还会在通知栏上显示通知。它正在运行查找您可以将您的代码与我的代码进行比较并更正错误（如果有的话）。 我希望这是有帮助的。

我的消息仅在我开始使用时完成：
Bundle extras = intent.getExtras();
String message = (String)extras.get("message");
Log.d("Tag", "msg:" + message);
