How to implement push notifications in Android

Question

I try to use more than one day to implement a simple PUSH notification using gcm, but could not implement it.

When I add this permission

<permission android:name="Android.Test.permission.C2D_MESSAGE" android:protectionLevel="signature" /> 

I get this error message while debugging using a mobile device

 pkg: /data/local/tmp/Android.Test Failure [INSTALL_PARSE_FAILED_MANIFEST_MALFORMED] 

Can someone suggest me what I'm doing. for further help I put my entire manifest.xml file

 <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="Android.Test" android:versionCode="1" android:versionName="1.0"> <uses-sdk android:minSdkVersion="14"/> <permission android:name="Android.Test.permission.C2D_MESSAGE" android:protectionLevel="normal" /> <uses-permission android:name="Android.Test.permission.C2D_MESSAGE" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <application android:label="@string/app_name" android:icon="@drawable/ic_launcher"> <activity android:name="MainActivity" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN"/> <category android:name="android.intent.category.LAUNCHER"/> </intent-filter> </activity> <receiver android:name="com.google.android.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="Android.Test" /> </intent-filter> </receiver> <service android:name=".GCMIntentService" /> </application> </manifest> 

Edit 1: This is how I try to send a message from C # to my Android device. I found this code on a blog.

 private string SendGCMNotification(string apiKey, string postData, string postDataContentType = "application/json") { ServicePointManager.ServerCertificateValidationCallback += new RemoteCertificateValidationCallback(ValidateServerCertificate); // // MESSAGE CONTENT byte[] byteArray = Encoding.UTF8.GetBytes(postData); // // CREATE REQUEST HttpWebRequest Request = (HttpWebRequest)WebRequest.Create("https://android.googleapis.com/gcm/send"); Request.Method = "POST"; Request.KeepAlive = false; Request.ContentType = postDataContentType; Request.Headers.Add(string.Format("Authorization: key={0}", apiKey)); Request.ContentLength = byteArray.Length; Stream dataStream = Request.GetRequestStream(); dataStream.Write(byteArray, 0, byteArray.Length); dataStream.Close(); // // SEND MESSAGE try { WebResponse Response = Request.GetResponse(); HttpStatusCode ResponseCode = ((HttpWebResponse)Response).StatusCode; if (ResponseCode.Equals(HttpStatusCode.Unauthorized) || ResponseCode.Equals(HttpStatusCode.Forbidden)) { var text = "Unauthorized - need new token"; } else if (!ResponseCode.Equals(HttpStatusCode.OK)) { var text = "Response from web service isn't OK"; } StreamReader Reader = new StreamReader(Response.GetResponseStream()); string responseLine = Reader.ReadToEnd(); Reader.Close(); return responseLine; } catch (Exception e) { } return "error"; } 

This is what I get in responseLine code

 {"multicast_id":7357801824672,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]} 

thanks

 try this one 

 <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16"/> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.GET_ACCOUNTS" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <permission android:name="com.google.android.gcm.demo.app.permission.C2D_MESSAGE" android:protectionLevel="signature" /> <uses-permission android:name="com.google.android.gcm.demo.app.permission.C2D_MESSAGE" /> <!-- This app has permission to register and receive data message. --> <uses-permission android:name="com.google.android.c2dm.permission.RECEIVE" /> <!-- Main activity. --> <application android:icon="@drawable/ic_launcher" android:label="@string/app_name" > <activity android:name=".MainActivity" android:label="@string/app_name" android:screenOrientation="portrait" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <receiver android:name="com.google.android.gcm.GCMBroadcastReceiver" android:permission="com.google.android.c2dm.permission.SEND" > <intent-filter> <!-- Receives the actual messages. --> <action android:name="com.google.android.c2dm.intent.RECEIVE" /> <!-- Receives the registration id. --> <action android:name="com.google.android.c2dm.intent.REGISTRATION" /> <category android:name="Android.Test" /> </intent-filter> </receiver> <service android:name=".GCMIntentService" /> </application>

The response code contains a response, you are sending invalid registration data

  "results":[{"error":"InvalidRegistration"}] 

Php code example:

  $postdata = array( 'registration_ids' => array('your_device_registration_key'), 'data' => 'message' ); $headers = array( 'Authorization: key=' . YOUR_API_KEY, 'Content-Type: application/json' );
