A memory leak happens when your code allocates memory for an object, but never deallocates it. This can happen for many reasons. ... No matter the cause, when a memory leak occurs the Garbage Collector thinks an object is still needed because it's still referenced by other objects. But those references should have cleared.

What is the main cause of memory leaks in application?

Holding the references of the object and resources that are no longer needed is the main cause of the memory leaks in android applications. As it is known that the memory for the particular object is allocated within the heap and the object point to certain resources using some object reference.
