A1: If current state of Sd card is SHARED it means that it has connected to PC in MSC mode, you can check this case as following:
String state = Environment.getExternalStorageState();
if (Environment.MEDIA_SHARED.equals(state)) {
// Sd card has connected to PC in MSC mode
}
A2: You can force to turn off usb mass storage connection by calling:
MountService.setUsbMassStorageEnabled(false);
or
StorageManager.disableUsbMassStorage();
but unfortunately, both these API are not public accessible?!
