api - How to safely remove SD card programmatically on Android

Question

I want to let the user safely remove the SD card in my program, but it seems the Android 2.2 public API does not provide a way to do this. Does anyone know what's a proper way to do it?

Answer 1

You need to take the user to the device's built-in Settings. I think this will work.

    Intent i = new Intent(android.provider.Settings.ACTION_MEMORY_CARD_SETTINGS);
    startActivity(i);

Unmounting the SD card is one of those actions which could be used maliciously if it wasn't under full user control. If it could be done purely in software (without user intervention) then code could disrupt other apps running on the device.
