What directory should the Android webapp default to creating an annex in?

Same as the desktop webapp, users will be able to enter a directory they want the first time they run it, but to save typing on android, anything that gets enough votes will be included in a list of choices as well.

/sdcard/annex (81%)

Whole /sdcard (6%)

DCIM directory (photos and videos only) (9%)

Same as for regular git-annex. ~/annex/ (3%)
