Try it with context,

String m_androidId = Settings.Secure.getString(getApplicationContext().getContentResolver(), Settings.Secure.ANDROID_ID);

Personally, I wouldn't use ANDROID_ID. It's been known to be null sometimes and it can change after a factory reset. The device id on the other hand is always non-null (in my experience at least), and unique.

You can add this code to your Activity to retrieve the unique device id of the phone:

TelephonyManager tm =
  (TelephonyManager)this.getSystemService(Context.TELEPHONY_SERVICE);

String device = tm.getDeviceId();
