how to identify incoming call and outgoing call in android

how to get the events of incoming call and outgoing call in android separately. Actually i was trying to develop an application that open on incoming call if number is exist in database and it work OK. but if i call from the device(outgoing call) and if number is exist in database still it open my application. i want to restrict to open my application on outgoing call.

my manifest contain i receive incoming call like this:

<receiver android:name=".IncomingCallReceiver" >
    <intent-filter >             
        <action android:name="android.intent.action.PHONE_STATE" />             
    </intent-filter>
</receiver>

IncomingCallReceiver:

MyPhoneStateListener phoneListener=new MyPhoneStateListener(context);
TelephonyManager telephony = (TelephonyManager)
context.getSystemService(Context.TELEPHONY_SERVICE);
telephony.listen(phoneListener,PhoneStateListener.LISTEN_CALL_STATE);

MyPhoneStateListener:

public void onCallStateChanged(int state,String incomingNumber){
      switch(state) {
          case TelephonyManager.CALL_STATE_IDLE:
              Log.d("DEBUG", "IDLE");
          break;
          case TelephonyManager.CALL_开发者_Python百科STATE_OFFHOOK:
              Log.d("DEBUG", "OFFHOOK");                        
              Intent i = new Intent(context, MyMainActivity.class);
              i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
              context.startActivity(i);
          break;
          case TelephonyManager.CALL_STATE_RINGING:
              Log.d("DEBUG", "RINGING");
          break;
    }
}

can anyone help me to differentiate outgoing call from incoming call so i'll handle this events.

Thanks in advance.

i want to restrict to open my application on outgoing call.

on case TelephonyManager.CALL_STATE_OFFHOOK: check if the previous state was CALL_STATE_RINGING or CALL_STATE_IDLE (for example by settings a different flag in both cases).
In the latter case proceed with opening your application, else do nothing

add <action android:name="android.intent.action.NEW_OUTGOING_CALL" /> in your receiver and process it in your onReceive() method.

<receiver android:name=".IncomingCallReceiver" >
    <intent-filter >             
       <action android:name="android.intent.action.PHONE_STATE" />
       <action android:name="android.intent.action.NEW_OUTGOING_CALL" />             
    </intent-filter>
</receiver>
