Thanks. Great idea, didn't think about that. See new patch.

I don't think that it is a lot of fun to call Android UI code from C as it is normally only done from Java.
The same problem occurs in dropbear on Android. There, it is solved by including a NetBSD version of getpass.c: https://github.com/CyanogenMod/android_external_dropbear/blob/master/netbsd_getpass.c .
If including NetBSD code is okay, the new patch will work. There currently is very limited use for this on Android, however, as there is no libcurl by default on Android. So, the only usage is git-imap-send, which works fine with this patch.
Compiling libcurl for Android should be possible with some work, though. So compat/getpass.c would be used for libcurl/HTTP access, too.
