i have fixed my xoom and updated to latest beta. im about to start a 5 hours print. One thing i noticed and that might be a good feature is to be able to print from the controller sd.
will report back when the print is done, im loadling it to gdrive 
ok, make sure to enable the status bar in the options, because the non-statusbar temperature label has a memory leak and can cause garbage collector runs which lead to stuttering.
SD Card printing is on the list for future feature, but my printer does not have a sd card yet (for testing).
cool, gdrive is not working fine on the tablet, it dies. Its a 30mb gcode file, so, i enabled the 30mb bumps heap memory thing and its loading quite fast!
30Mb gcode is huge. The largest I test so far was ~15MB. I’m curious if it works.
Yeah, is insane, so its loading, at 28% it slowed down, i guess it will take like 20 mins to load the file
I’m concerned that it won’t work if it already slows down at 28%.
Maybe I need to allow bumping up more
heap memory than just 30MB.
39% and loading 
44.9%
49
51, looks its getting slower.
54
oh man. much too slow. I need to test with 30MB files as well …
63%, i will send you the gdrive link of this file
sounds good. thanks
wow. 1100057 lines in ~500 layers.
I did some optimizations and now it loads the 30MB file in ~250 seconds. Heap is growing up to 145MB 
I will upload a new beta version with the fix later today.
cool, im printing now (no from the xoom), but if i get the new beta today, i will leave it printing tonight. Its a 4-5 hours print.
I have uploaded the new version 1.34 to Google Play. As always it can take some hours until you see the update.
Fix description: In addition to the 30MB allocation to bump up the heap size, I do 5MB allocations for every 40000 gcode lines. This prevents android from doing thousands of tiny allocations which is slow.
@Nicolas_Arias did you try the new version v1.37 ? My Galaxy tab loads your large gcode file in ~300 seconds. (Still some room for improvement)
