For example, consider you are doing some configuration check before doing operation in onStart() method(See the snippet below). So managing these considerable amount of code inside life-cycle method such as onStart(), onStop() is difficult to maintain.įurther, there is no guarantee that, code written in onStart() will be getting called before onStop(). Unlike the Windows platform, where Android applications cannot control their life cycles, application components must listen to changes in the state of the application and respond appropriately, paying particular attention to being ready to be terminated at any time. It states that, in a real time application we write plenty of code which depends on life-cycle of component( e.g. You should read the documentation further, It's not that lengthy though -) What is the use of this in real application. These components help you produce better-organized, and often lighter-weight code, that is easier to maintain. The Lifecycle we will introduce in this article is one of the lifecycle-related libraries. It contains a number of column architecture related components. Android Architecture Components is an application architecture built by Google that builds an APP. These components help you produce better-organized, and often lighter-weight code, that is easier to maintain. Lifecycle-aware components perform actions in response to a change in the lifecycle status of another component, such as activities and fragments. The Android Architecture Components refer to the 'architecture components' here. Here are some points that needs clarification. Lifecycle-aware components perform actions in response to a change in the lifecycle status of another component, such as activities and fragments. I have been trying out Navigation Component for a while now but somehow not getting the reason (or explanation) behind current Lifecycle of Navigation Component. Use lifecycle-aware components to handle pausing animated drawables when while app is in the background and resume drawables after the app is in the foreground Use lifecycle-aware components to enable live updating (streaming) of network data while an app is in the foreground and also to automatically pause when the app goes into the background. Starting and stopping network connectivity. You can also use lifecycle-aware components to terminate buffering when your app is destroyed. Use lifecycle-aware components to start video buffering as soon as possible, but defer playback until app is fully started. LiveData, a lifecycle-aware component, allows your app to automatically update the UI when your use changes locations. Use lifecycle-aware components to enable fine-grained location updates while your location app is visible and switch to coarse-grained updates when the app is in the background. When two applications have the same priority, the process that runs the longest in the lower-priority state is first terminated.Switching between coarse and fine-grained location updates.When resources are reclaimed, the order in which the processes are terminated is determined by their application priorities, and the priority of an application is equal to the priority of the component with the highest priority.You can use the Android:process property to run the same application component in a different process, or to have multiple applications share a process Lifecycle is a process that tells us about the Events performed on an Activity/Fragment. By default, each Android application runs through their own processes, each running in a separate Dalvik instance, and each application's memory and process management is handled exclusively by the runtime. The LifeCycle component is concerned with the Android LifeCycle events of a component such as an Activity or a Fragment, it has three main classes that we’ll deal with: 1.Unlike the Windows platform, where Android applications cannot control their life cycles, application components must listen to changes in the state of the application and respond appropriately, paying particular attention to being ready to be terminated at any time.
