I need to write to the SD card so the user can transfer data files created by my app to other devices. getExternalFilesDir() does not always point to the SD card, even when there is one. As the developer docs say:
Quote: Note: don't be confused by the word "external" here. This directory can better be thought as media/shared storage. It is a filesystem that can hold a relatively large amount of data and that is shared across all applications (does not enforce permissions). Traditionally this is an SD card, but it may also be implemented as built-in storage in a device that is distinct from the protected internal storage and can be mounted as a filesystem on a computer. In devices with multiple "external" storage directories (such as both secure app storage and mountable shared storage), this directory represents the "primary" external storage that the user will interact with. ---- and indeed my testing confirms this. On 2 out of 3 Android tablets I have for testing, getExternalFilesDir() directs me to built- in memory, not the removable SD card. And this posting on Stackoverflow indicates that there is no general solution for this problem: http://stackoverflow.com/questions/5524105/how-could-i-get-the-correct-external-storage-on-samsung-and-all-other-devices How can this be? Is it truly impossible to write a generic Android app that for sure will access the SD card? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
