Question

I see files from apps all over in the sd card so there doesn’t seem to be an android standard. But when saving app related files externally, is there a recommended directory path to use or a common practice?

ie. (sdcard)/myapp/ or (sdcard)/apps/myapp/

Answer 1

Simply use Environment#getExternalStoragePublicDirectory(String type) with the various String types for a specific folder.

This creates folders in .../sdcard/Android/data/my.package.name/<type>.

From the Developer’s Guides:

In API Level 8 or greater, use getExternalStoragePublicDirectory(), passing it the type of public directory you want, such as DIRECTORY_MUSIC, DIRECTORY_PICTURES, DIRECTORY_RINGTONES, or others. This method will create the appropriate directory if necessary.

If you’re using API Level 7 or lower, use getExternalStorageDirectory() …
