Detecting/Verifying SD Card Drive

由 痴心易碎 提交于 2019-12-08 09:40:19
问题 Is there a way to detect all SD Card drives connected to a Desktop computer? In Windows, SD Cards are visually distinct from other devices like built-in hard drives or similar. Is there a way to tell if a drive is an SD Card drive or not? A Java way of listing all available filesystem roots for example is using the listRoots() method but it cannot tell the filesystem types such as external, internal, OS drive or whatever. Is this even possible in pure Java? Note: I'm not asking to detect the

Android - Find all internal and external storage

由 和自甴很熟 提交于 2019-12-08 05:45:25
问题 So I've noticed that from device-to-device, there are many different configurations for internal vs. external. On my Evo there's just internal storage and the external SD card, but on a Droid Incredible from the same year, there's internal storage, internal SD card (~8GB) and external SD card (default 1GB). Presumably there are other configurations as well, and there will be more forthcoming. However, all I can seem to find about enumerating the number of storage media available are things

由 拜拜、爱过 提交于 2019-12-08 05:00:57
问题 I am currently trying to write a small program to check my SD card on my Galaxy S3 for music then check my music folder on my computer and copy anything I don't have on my phone to it and vice versa.

Append (add) String data to an SD Card text file in an Android application

由 旧街凉风 提交于 2019-12-07 19:39:17
问题 Just a quick point here. Although my code seems to be okay storing String data etc. in a new file using the standard techniques of writing to a mytext.txt file in an internal or external (SD Card) storage, it is of more use to me for my App to add more data to the same file in the same directory by repeating allowing the user to repeat the process (e.g. a user input and button save) or closing the App and starting over again, so the data permanently remains unless the user chooses to manually
