external storage media is very poor, so you must check its availability before use, if you can use Final String state = Environment.getexternalstoragestate (); B. Get the directory gets the path to the external storage card In fact, the path to the external memory card is "/mnt/sdcard", so you can access it directly by writing to it.

Problems that you may encounterThe Android system itself has its own storage, and the SD card can be used to expand the storage space. The former is like the hard disk in PC, the latter is good to move hard. The former space is small, the latter space is large, but the latter is not necessarily available. These issues may be encountered when developing applications that handle local data access: Need to determine whether the SD card is availa

There are two types of file storage areas for Android devices:internal storage and external storage ("internal" and "external" storage).The name comes from early Android, when most Android devices offer two types of storage: built-in nonvolatile memory (internal storage) and removable Storage such as micro SD cards (ex
