How to programmatically turn on the speaker when making / receiving a call?

Question

Hey. I am new to android and still involved in the learning process. I am currently planning to make an application that will automatically turn on the speaker when the call is connected. Below are the codes.

audiomanager = (AudioManager) contex.getSystemService(Context.AUDIO_SERVICE);

  @Override
    public void onCallStateChanged(int state, String incomingNumber) {
               case TelephonyManager.CALL_STATE_OFFHOOK:
                           am.setSpeakerphoneOn(true); 
               break;
         }

I tested my code on Android android 2.1..sdk 7..i using audiomanager.setSpeakerphoneOn (true); and add the MODIFY_AUDIO_SETTINGS permission in the manifest, you can turn on the loudspeaker .. but it seems like it can't ... so can anyone help? thanks in advance.

Make sure the spelling is contextcorrect

audiomanager = (AudioManager) contex***t***.getSystemService(Context.AUDIO_SERVICE);
