Garbage Collector is a daemon thread. You can neither stop it nor call it. You can just make a request, eg.- System.gc(), to the garbage collector.

Plus, garbage collector helps improving the performance.

If you do not want to get your objects getting collected by GC then just Hold the reference.

If your object is getting collected prematurely, it is a symptom that you have a bug in the design of your application.

When implementing applications (like games etc) that need to avoid garbage collection because of the small pauses it introduces every time the garbage collector executes,

All you can do is avoid to keep on creating objects and try to reuse as much as possible the objects instances you already have.

This can be done in different ways take a look at this

When using CalendarView I noticed one quite surprising thing. When I set calendar heigh as number, ex. android:layout_height="400dp" garbage collector is not run, however when I set it as match_parent garbage collector is run every time I switch orientation. Perhaps that's the answer?
