If you are looking for delete cache of your own application then simply delete your cache directory and its all done !

public static void deleteCache(Context context) {     try {         File dir = context.getCacheDir();         deleteDir(dir);     } catch (Exception e) { e.printStackTrace();} }  public static boolean deleteDir(File dir) {     if (dir != null && dir.isDirectory()) {         String[] children = dir.list();         for (int i = 0; i < children.length; i++) {             boolean success = deleteDir(new File(dir, children[i]));             if (!success) {                 return false;             }         }         return dir.delete();     } else if(dir!= null && dir.isFile()) {         return dir.delete();     } else {         return false;     } }

Kotlin has an one-liner

context.cacheDir.deleteRecursively()
