how to identify incoming call using android? -

i want record incoming call,any body knows please give idea that,other wise give idea how know incoming call,

thanks all

i believe should write broadcast receiver i.e. make class , extend broadcastreceiver

public class myclass extends broadcastreceiver {  // functions here } 

in manifest.xml file write

<receiver android:name="myclass">             <intent-filter>                              <action android:name="android.intent.action.answer">/action>             </intent-filter>         </receiver> 

this call myclass ever call received
