android - GCM Invalid sender error -

i'm stuck while on mysterious problem. implemented gcm in android app, receive invalid_sender error.

• my sender_id id url of google project.
• the android push notifications on

the weird thing have registration id send notifications to. console looks this:

03-26 09:39:20.233: i/<test>(19761): registered: apa91bg6-   o3onzt50eajyvj5ketv3qalpon2sfopxez7slamaaokhtn6emdjb91gfiwkftzkjiub6uoek4o-  wqp7kk2ozgqjz1vczzs0wddqtjfacfyfzfb7sew3is1sd4cajcdze4la1f0hxzc7ss1uiyhxx-xxxx 03-26 09:48:23.522: i/<test>(19925): gcmintentservice  03-26 09:39:20.670: i/<test>(19761): on error invalid_sender 

inside oncreate:

gcmregistrar.checkdevice(this); gcmregistrar.checkmanifest(this); final string regid = gcmregistrar.getregistrationid(this); if (regid.equals("")) {     log.i("<test>", "registering");         gcmregistrar.register(this, "2194354949xx"); } else {     log.i("<test>", "already registered: " + regid); } 

broadcastreceiver:

 public class gcmbroadcastreceiver extends com.google.android.gcm.gcmbroadcastreceiver{     @override     protected string getgcmintentserviceclassname(context context){         return "be.xxx.xxx.system.gcmintentservice";     } } 

gcmintentservice:

 public class gcmintentservice extends gcmbaseintentservice {     @override     protected void onerror(context arg0, string errorid) {         log.i("<test>","on error " + errorid);     }      @override     protected void onmessage(context arg0, intent intent) {         log.i("<test>","onmessage " + intent.getextras().tostring());     }      @override     protected void onregistered(context arg0, string regid) {         log.i("<test>","registration id: " + regid);     }      @override     protected void onunregistered(context arg0, string regid) {         log.i("<test>","onunregistered " + regid);     }      public gcmintentservice() {         super("2194354949xx");         log.i("<test>","gcmintentservice ");     } } 

manifest:

 <permission     android:name="com.xx.xx.permission.c2d_message"     android:protectionlevel="signature" /> <uses-permission android:name="com.smstiming.hezemans.permission.c2d_message" /> <uses-permission android:name="com.google.android.c2dm.permission.receive" /> <uses-permission android:name="android.permission.internet" />  <uses-permission android:name="android.permission.get_accounts" /> <uses-permission android:name="android.permission.wake_lock" /> <uses-permission android:name="android.permission.vibrate" />    <receiver android:name="be.xx.xx.system.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.smstiming.hezemans" />         </intent-filter>     </receiver>   <service android:name="be.xx.xx.system.gcmintentservice" />  

finally got around this. accidentally trying use the 'project id' instead of 'project number'. google developer console provides both on overview page, make sure using correct one.
