Hi

I want to create a service in Android which will initially ask user if they want to start Bluetooth and set the Bluetooth discovery.

My question is 1) Can I launch in the service following activities?

if (!mBluetoothAdapter.isEnabled())
{
    Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
    startActivityForResult(enableBtIntent, 0);
}

// Set Phone Discoverable for 300 seconds.
Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 600);
startActivity(discoverableIntent);

2) I want to set discoverabilty of the phone on for lifetime of application. Is it possible?

3) I want to access empty space available on SD card. How should i do it?

Thanks in advance.
