Halton, I have two questions about this:

1. Will the deflated library be stored on disk? That would only give the 
startup penalty on first launch, at the expense of needing more space.



Yes, decompressing will take some time, and we have 2 library(decompressed in 
lib directory, and the compressed in apk).

However, due to the Android’s limitation, we can’t delete the compressed 
one(because it resides in an signing package).

2. Do you think the packaging tools (make-apk, app-tools) could do the lzma 
step before creating the apk? Then we wouldn't have so many extra releases.



OK, we can ship an uncompressed library with make_apk, and this will consume 
some more time for their first time to enable the ‘use_lzma’ flag.
