Cannot resolve method startActivityforResults in this code

Why cannot resolve this method in a class? This class is out off main android class. If I put the method in main class work fine, but not in other class.

class blu {

        public blu(){

        }

        public boolean comprobarBluetooth(Context context){


            CharSequence text = "No tiene Bluetooth";
            int duration = Toast.LENGTH_SHORT;
            Toast toast = Toast.makeText(context, text, duration);
            toast.show();

            //mirem si hi ha bluetooth al aparell
            BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

            if(mBluetoothAdapter==null) {

                //disparo un toast per informar

                return false;
            }else{

                if (!mBluetoothAdapter.isEnabled()) {
                    //si està apagat obrim el dialeg per activarlo.
                    Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
                   startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
                }//SI startActivityForResult torna un OK faig return true, i executo el metode de buscar dispositivos

            }
           return true;
        }

If context is an instance of Activity you can use:

((Activity) context).startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);

If it is not an instance of Activity you will get an exception.

startActivityForResult() is a method on Activity. You cannot call startActivityForResult() from some random Java class. You need to call startActivityForResult() on an Activity, specifically the activity where you plan on getting the results via onActivityResult().

startActivityForResult is a method of the Context class. You will have to call context.startActivityForResult(...).
