Answer 1

Simply says,

Both are same concepts, but some key differences. Thread is a java(java.lang) concept and Handler is a android(android.os)OS concept.if you are using Handler instead of Thread , your OS will automatically manage the working of background processes. But if you are using Thread,it is not dependent on your android OS. So Threads can't manage memory efficiently as compared to Handler.
