Using quicken for shared APKs on Go devices may save RAM. # Note that this is a trade-off: here we trade clean pages for dirty pages, # extra cpu and battery. That's because the quicken files will be jit-ed in all # the processes that load of shared apk and the code cache is not shared. # Some notable apps that will be affected by this are gms and chrome. # b/65591595. pm.dexopt.shared=quicken # Default heap sizes.
