Getting OOM on encryptShared method in android SDK

[tizisdeepan]

Description and steps to reproduce
When trying to encrypt multiple files that are fairly large - around 60MB each, the SDK returns an OOM

Expected behavior
OOM should not be returned and all files should be encrypted successfully one by one

Platform (please complete the following information):

• Device: Google Pixel 4a
• OS: Android 13
• E3Kit Version 2.0.10

@tizisdeepan could you please share your encryption code?
Also, how many files does it process before throwing OOM?
