Lint Usage Summary of Android performance optimization

to be honest, pay attention to lint. The lint tool is often helpful for memory optimization, performance optimization, code specification, etc. in Android application development. After the development of each module, lint, there is an unexpected harvest.
Introduction:Static code analysis tools, no need to run, no test casesScan the entire project to analyze the following potential issues, which are categorized to indicate problem description, problem location, and provide reasonable suggestions for modification(This is the key ah, regardless of the wood has a big problem, look at these problems and descriptions, can also be addicted to AH): ====================================Correctness CorrectnessSecurity performance Performance Usability availability accessibility Accessibility internationalization internationalization =================================== =

1) Performance

Layout Performance (formerly Layoutopt tool, can solve useless layouts, too many nesting, too many layouts, overdraw)

Other performance (e.g., Declaration of objects at Draw/layout)

2) unused resources, lack of resources (adaptation of different resources)

3) Replacement of resources with higher performance----eg:sparsebooleanarray sparseintarray

4) Internationalization issues (hard coding)

5) Icon problem (duplicate icon, wrong size)

6) Usability issues (such as input type for non-specified text fields)

7) Error in manifest file--unregistered activity service, etc.

8) memory leaks---such as: improper use of handle.

9) The memory resources timely recovery---such as:Typedarray not recycled resources, etc.
