Battery usage has always been a top concern for smartphone enthusiasts. As more and more applications increase, people need to charge at least twice a day. This also causes the battery problem to be thrown to the Cusp again. To this end, the android team provided a series of "courses" for its developers to teach some smart phone power-saving tips, such as how to

method that the user can call before interacting with the fragment. For example, enable features such as camera devices, location services, and so on in this method. However, as these services can cause battery consumption to be very fast, it is generally necessary to minimize the use of such applications to prolong battery life.2. Callback method thrown when de

The state that the application (or activity) executes is called a process (progress). In the Android operating system, each application is a process. The Android framework maintains a unique activity history stack and observes each application process. At the same time, the system platform will manage the system memory according to the system's memory usage and activity state. In addition to running the pro

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. By default, each Android application runs through their own processes, each running in a separa
