Android clears useless resource files and android resource files from the project.

Android clears useless resource files and android resource files from the project.
1. Call the Android lint command to find useful resources and generate a list:

Command: lint-check "UnusedResources" [project_path]> result.txt
After execution, a configuration file is generated. The content is as follows:

Ii. Use the code to automatically delete useless files:

Public class DelAction {public static void main (String [] args) throws IOException {String projectPath = "***"; bufferedReader reader = new BufferedReader (new FileReader ("result path"); String line; int count = 0; while (line = reader. readLine ())! = Null) {if (line. contains ("UnusedResources ")&&! Line. contains ("res/value ")&&! Line. contains ("appcompat") {count ++; int end = line. indexOf (":"); if (end! =-1) {String file = line. substring (0, end); String f = projectPath + file; boolean flag = new File ("[complete file path]" + f. replace ("***","")). delete (); System. out. println ("[complete file path]" + f + "=> del =>" + flag );}}}}}

We often need to repeat the above operations multiple times to completely clear useless resource files in the project.
