The project needs to be changed and the UI needs to be adjusted. The result is that a bunch of junk Resources in the project that are not used but are not cleaned up, not to mention the project size, for new project users or those who read code from other modules, these uncleared resources may also cause problems. Therefore, it is best to clear the garbage, for a slightly larger project, manual cleanup is obviously unrealistic. This requires a method to do these tasks.Clear resource files

If -- lint has been specified on the command line, gawk issues a warning about this.
With gawk and several other awk implementations, when given an array argument, the length () function returns the number of elements in the array. (c. e .) this is less useful than it might seem at first, as the array is not guaranteed to be indexed from one to the number of elements in it. if -- l
is developing extensions which, while well intentioned, will aggravate one of the language's biggest problems: there are already too limit versions. This creates confusion.
The ECMA committee, the manager of the language, is expanding it and is deliberately deteriorating its biggest problem: There are too many versions. This is the root cause of chaos.

5. Use code analysis tools
The value of testing is instilled in developers in the early stages of their programming journey. This year, the rise of unit testing, test-driven development, and agile methods have been widely used in every process of the development cycle. However, testing is only one of the many tools that can improve the code quality.
Back to the early stage, when the C language is still a new

In our daily development of Android, often encountered writing a normal code, but the system error, and then according to the system prompts,will help us automatically add a @suppresslint ("Newapi") and then undo the errorThe reason is that our code uses a method that is higher than the android:minsdkversion= (that is, the minimum compatible version) we have set.The general workaround is to add @suppresslint ("Newapi") or @targetapi () to the method or set a higher minimum version1.@SuppressLint

Enable all warning options unless there is an excellent reason for not doing so. 10. lint was initially used to check unportable code in C language, but now it is not just a portability check program, you can also check out the featu
