Android Pro App still hangs

[MCP1]

I'm facing the same hanging/resetting problems with the pro version 13443 on an old Android 6.01 tablet with just 1GB memory (450MB free). The crash almost always happens if I switch to another app and then come back to the Prime. It happens too if I stay on the app but less frequently.

The free version (13443) works fine on the same tablet. On my Android 7.0 phone with 3GB (500MB free), the pro version works without a single hiccup.

Digging a little more on the tablet logs, it seems before the crash occurs this pair of errors shows up several times:

13:15:59.908 art (31706)
Large object allocation failed: ashmem_create_region failed for 'large object space allocation': Too many open files

13:15:59.908 art (31706)
Throwing OutOfMemoryError "Failed to allocate a 47640 byte allocation with 12043348 free bytes and 366MB until OOM"

It seems weird it fails trying to allocate just about 47K when there are 12M free in the corresponding memory pool (and 366MB overall). Maybe this gives a clue to where the problem may be.
