i have below 2 methods in class gcmintentservice, onregistered() method gets called upon registeration regid, however, when send message onmessage() not called.

@override protected void onregistered(context context, string registrationid) {     log.i(tag, "onregistered called");     gcmregistrar.setregisteredonserver(context, true); }  @override protected void onmessage(context context, intent intent) {     log.i(tag, "received message");     sendnotification("a", "b"); }

below manifest 

<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="com.myapp.permission.c2d_message" /> <uses-permission android:name="com.google.android.c2dm.permission.receive" /> <uses-permission android:name="android.permission.read_phone_state" /> <uses-permission android:name="android.permission.access_network_state" /> <uses-permission android:name="android.permission.vibrate" />     <receiver         android:name="com.google.android.gcm.gcmbroadcastreceiver"         android:permission="com.google.android.c2dm.permission.send" >         <intent-filter>              <!-- receives actual messages. -->             <action android:name="com.google.android.c2dm.intent.receive" />             <!-- receives registration id. -->             <action android:name="com.google.android.c2dm.intent.registration" />             <category android:name="com.myapp" />         </intent-filter>     </receiver>      <service android:name="com.myapp.gcmintentservice" />

i getting registration id : 

            regid = getregistrationid(context);              //check if have registered.             if (regid.length() == 0) {                 gcmregistrar.checkdevice(myactivity.this);                 gcmregistrar.checkmanifest(myactivity.this);                 gcmregistrar.register(myactivity.this, sender_id);             } else {                 log.i(tag, "you registered.");                 log.i(tag, "the registration id : " + regid);             }

in manifest, use below code receive message:

<permission     android:name="com.myapp.permission.c2d_message"     android:protectionlevel="signature" />  <uses-permission android:name="com.myapp.permission.c2d_message" />  <!-- app has permission register , receive data message. --> <uses-permission android:name="com.google.android.c2dm.permission.receive" />

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
