推荐答案

除非你的目标很老的手机，你不必担心没有外部存储。只要你使用 Environment.getExternalStorageDirectory（）作为您的参考，你应该不会有问题，但如果你是绝对在意这一点，你可以，如果外部检查存储不存在，然后选择去内部存储设备。 检查出从开发文档链接多一点洞察力。

Unless you're targeting VERY old phones, you don't need to worry about not having external storage. As long as you use Environment.getExternalStorageDirectory() as your reference, you shouldn't have a problem, though if you're absolutely concerned about this you can check if the external storage doesn't exist and then opt to go to internal storage. Check out this link from the developer docs for a little more insight.

如果外部确实是不可用，然后你可以保存到内存，但你必须要声明一个新的许可的，这可能会挡住一些人。

If External truly isn't available, you could then save to Internal memory, but you will have to declare a new permission for that, which may ward off some people.
