如何在 Android 上以编程方式安全地移除 SD 卡 [英] How to safely remove SD card programmatically on Android

问题描述

我想让用户在我的程序中安全地移除 SD 卡，但 Android 2.2 公共 API 似乎没有提供这样做的方法.有谁知道这样做的正确方法是什么?

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?

推荐答案

您需要将用户带到设备的内置设置.我认为这会奏效.

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);

卸载 SD 卡是其中一种操作，如果它不受用户的完全控制，可能会被恶意使用.如果它可以完全在软件中完成(无需用户干预)，那么代码可能会干扰设备上运行的其他应用.

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.
