Yes, android provides an internal storage directory for applications and
also a related place for them to create sqlite databases.
At the java level, finding the appropriate path is handled automatically by
some of the typical functions, but you can determine it with
Context.getDir() and Context.getFileDir() - if you want to do something in
the NDK, probably call one of those from java and pass the result to your
ndk routines as a java string, where you would convert it to a native string
for the posix file functions.
Using root access is to be avoided as it's not available on unmodified
devices, and should cause some due suspicion ("why does this app need
that?") on the part of the user even where it is. It's also entirely
outside the scope of the ndk list.
