android manifest application class

For those who have just been familiar with the Android operating system, they are deeply attracted by the functions of this open-source mobile operating system. In this article, we will have a deep understanding of this system by interpreting the concepts related to Android power management. Next we will discuss in detail at the Java application level,

out where a few good programming habits are being violated. Strictmode will help you verify that your application has a memory leak and that your application is attempting to perform a lengthy blocking operation that should be unloaded to threads or other channels (see the second point). The Strictmode Class (Android.os.StrictMode) is introduced into the Androi

Android performance optimization and Android Application Performance OptimizationGoogle Performance Http://developer.android.com/intl/zh-cn/training/articles/perf-tips.html This article mainly involves some minor optimizations. Combined use can improve the overall performance of the App, but does not significantly improve the performance. An appropriate algorithm

speed up the power consumption. These development concepts directly affect the user's final experience, so let's talk about how to optimize the development of the user experience orientation in Android. Although it is not necessary to have a thorough understanding of the underlying system, you need to have a basic understanding. Android system layered Clear, the bottom is the Linux Kernel 2.6, on top of t

Registration and retrieval of fingerprint information are free of charge. There are two types of fingerprints: The debug fingerprint used for development can only be used in your own debug application; Official fingerprint. You only need the first one. The procedure is: first, the development environment s
