Although the difficulties of inter-process communication are introduced at the same time, it also brings stronger security.Android memory reclaim Principle The following describes the Resource Management Mechanism of the Android operating system at

?? A common feature of embedded devices is that memory capacity is relatively limited. When running more than a certain number of programs, or involved in complex calculations, it is likely that there is not enough memory, resulting in a system lag. The Android system is no exception, and it also faces the dilemma of physical

reference to the activity in it. The solution to this problem is to use a static inner class, and have a weakreference to its outer class, just as in the case of inner class W in Viewroot.6. Memory leak caused by object not cleaned in collectionWe usually add references to some objects to the collection, and when we don't need the object, we don't clean up its references from the collection, so the collect
