It is not quite as simple as that. Many Android devices have several kinds of external memory. There is the truly removable kind like a physical SD or micro SD card. Then there is built-in external memory that cannot be removed, but in every other respect it acts like external memory, especially in the relaxation of security requirements for access. That is, an application can write to the root of external memory (of whatever kind) but it cannot write to the root of internal memory. It has been my experience that Environment.getExternalStorageDirectory() which you mentioned generally points to the built-in kind of external memory. So if you want to access the real removable SD card file system there is no way I know of other than hard-wiring the actual path name, or letting the user enter it on a form (assuming the user even knows what the path name is). For example, on the Acer Iconia Tablet A-100 there is /mnt/sdcard (built-in "external" memory") /mnt/external_sd (removable SD card) But Environment.getExternalStorageDirectory() returns "/mnt/sdcard". -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
