In the process of developing an application, it is necessary to carry out the corresponding unit test.Next we write a simple Android application to complete the basic unit testFirst, we need to build an Android project, named JUnit.Then, create a service class, which is the class Personservice.java that needs to be tested:Package Cn.itcast.service;public class Personservice {public void Save (string username) {String sub = username.substring ( 6);} public int Add (int a,int b) {return a+b;}}In t

At the same time, the corresponding empty shape file is generated in the drawable-anydpi.3.

: ease of use? Memory leaks? Performance improvement? Robustness? And so on ...Ease of Use: the greatest feature of the tool class is ease of use, this viewholder is a typical use of the doctrine, we do not have to worry about writing some of the appropriate code, directly into the view and ID, cohesion loose coupling. and using the Generic template method, automatically with the external View sub-class adaptation, do not need us to manually force the reload.memory leaks: Some beginners, see th

In general scenarios, it may be better to analyze memory objects if the memory load is low, but it is recommended to do GC tuning based on experience if the ser
