contribute javadoc to a method in android/GT_APP/app/src/main/java/com/tencent/wstt/gt/utils/FileUtil.java

[129124]

Hi there, when I was reading the code of the function "public static boolean isPath(String path)" in android/GT_APP/app/src/main/java/com/tencent/wstt/gt/utils/FileUtil.java, I found it has no Javadoc. I would like to contribute by adding “returns true if the path is the same as @param path the path to check @return true if the path is in the list, false otherwise". Can you please check if this is correct? Thanks.
