this type, the number of times the garbage collector is started is much higher than other normal objects. With the support of this large object storage space, the number of calls raised by the garbage collector due to heap space fragmentation is greatly reduced, so that the garbage collector can make more reasonable memory allocations, thereby reducing the run-time overhead.
A good example is when running a hangouts application, in the Dalvik virtua
applications can send and receive data in the background, which theoretically eliminates the user's problem of too long a data flow bill in the absence of a Wi-Fi environment for a holiday or a long time.

upgrades, rather than OS upgrades.
Over the past few years, Gmail, Search (including Google Now and Voice Actions), Hangouts (previous talk), Chrome, YouTube, calendars ... These are all directly upgraded. With app upgrades, rather than OS upgrades, you can dramatically shorten the frequency of new features, which are upgraded about 6 months ago and now take only a few days.
This also poses the problem that each new version of Andoird has a new API
