Phonegap android 向其他应用程序用户发送通知
Phonegap android to send notification to other app uers
我有一个由我的同事开发的Android应用程序。该应用程序正在执行将一些文件上传到服务器的任务。我在应用程序中的角色是我必须从服务器向所有或选定的应用程序用户发送通知消息。
在服务器端，我正在使用 ASP.net 向所有Android应用程序用户发送推送通知。我知道我将不得不使用GCM。我对 GCM 进行了一些研究并尝试了一些示例 GCM 应用程序，但我可以看到的是，要使用 GCM 服务，必须注册设备，这很好，但是每次我关闭应用程序时，通知消息都没有传递并且应用程序崩溃。并且必须再次向GCM注册我的设备才能发送通知。
如何在卸载应用程序之前保持设备在 GCM 中注册。如何做到这一点？
我正在添加用于实现此目的的示例代码：
用于发送推送通知的服务器端代码：
string regId = "APA9xxxxxxxxxxxxxxxxxxxxxPx69PQ";
var applicationID = "AIxxxxxxxxxxxxxxxxxU";
var SENDER_ID = "xxxxxxxxxxx";
var value = "test message";
WebRequest tRequest;
tRequest = WebRequest.Create("https://android.googleapis.com/gcm/send"); tRequest.Method = "post";
tRequest.ContentType = "application/x-www-form-urlencoded;charset=UTF-8";
tRequest.Headers.Add(string.Format("Authorization: key={0}", applicationID)); tRequest.Headers.Add(string.Format("Sender: id={0}", SENDER_ID));
//Data post to the Server
string postData ="collapse_key=score_update&time_to_live=108&delay_while_idle=1&data.message="+ value + "&data.time=" + System.DateTime.Now.ToString() +"®istration_id=" + regId + "";
Console.WriteLine(postData);
Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
tRequest.ContentLength = byteArray.Length;
Stream dataStream = tRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();
WebResponse tResponse = tRequest.GetResponse();
dataStream = tResponse.GetResponseStream();
StreamReader tReader = new StreamReader(dataStream);
//Get response from GCM server.
String sResponseFromServer = tReader.ReadToEnd();
//Assigning GCM response to Label text
Response.Write(sResponseFromServer);
tReader.Close(); dataStream.Close();
tResponse.Close();

您还可以使用Streethawk标记用户(例如管理员用户或普通用户(，并可以管理您的推送消息
