An android activity life cycle is most precious thing to keep in mind for each developer. The logic of an android app building comes under the open logic of activity life cycle. Here we can see on create, on resume, on pause, on stop and on destroy methods (in the above specified life cycle). Each specified method are interlocked with each other at the runtime of an android application. Every method have equivalent role in implementing their function so as to perform without a runtime error. Of-course you might be thinking that generating a method without a proper function is impossible. Well let me say my point in saying that the proper use of timeline path of the activity life cycle can resist the runtime errors and can build a well quality application.
