TMK, apps running in the Java virtual machine on Android have an
imposed memory limit, but one time i've tested that and it seemed as
if my app was able to use a lot more - around 100MB, while the limit
was supposedly lower.

for native applications (NDK):

"the limit is actually not imposed on you, because it is only on the
Java heap.  There is no limit on allocations in the native heap..."

so since Qt on Android runs on the NDK and given how many gigs of RAM
some of these modern devices have, running out of memory seems
unlikely.
but who knows, i think this can be monitored via a task manager.
