为什么在模拟器外部存储在状态删除？ [英] Why the external storage on simulator is in state removed?

问题描述

我创建应用程序与存储在外部存储数据打不过的code不上我的模拟器工作，

I am creating App to play with storing data on the external storage, however the code doesn't work on my simulator,

String state = Environment.getExternalStorageState();

返回状态总是删除，以下是我的模拟器配置，其中我设置的大小SD卡作为200M，所以我觉得SD卡应安装在模拟器上。

The returned state is always removed, and below is my simulator configurations of which I set the size of the sd card as 200M, so I think the sd card should be mounted on the simulator.

你知道为什么吗？

推荐答案

我测试过你的初始化。那么，它的工作原理。有几件事情，你可能会想尝试：

I've tested your initialization. Well, it works. Several things you might want to try:

• 测试与SD卡工作在实际设备上您的应用程序。请问您的code给你正确的状态呢？这将意味着，它不是code，但真正的模拟器。



• 使用在的onCreate 以下code调用 super.onCreate 之后。它会给你敬酒的表现状态的实际工作路径到外部存储。

• Test your app on an actual device with working sdcard. Does your code give you the correct state there? That would mean, it's not the code but really the emulator.

• Use the following code in onCreate after the call to super.onCreate. It'll give you a toast showing state an actuall path to the external storage.

Toast.makeText(
    this,
    Environment.getExternalStorageState() + ", " +
    Environment.getExternalStorageDirectory(),
    Toast.LENGTH_LONG)
    .show();

请确保您的PC为SD卡文件可写空间。根据操作系统这个文件下可以找到你的＆LT;家＆GT; /安卓/ AVD /＆LT;设备名称＆gt; .avd / sdcard.img
