How to check if the string is valid Url path format

Understands that using Patterns.WEB_URL.matcher(url).matches() will able to validate if that string is a valid url, however it will required in a full format which contain https: / .com.

In my case, i want to validate if the json return a string in correct format for path e.g /images/slider/my/myImage.jpg; which does not contain https or any. How can i do this?

What i want to do is something like:

if(ImageUrl equal "/images/slider/my/myImage.jpg" FORMAT) {
//Do something here
} else //ImageUrl = myImage.jpg {
//Add "/images/slider/my/" infront of the text
}


P.s: My image link will be like www.abc.com/images/slider/my/myImage.jpg

U can use matcher if the string contain /images/slider/my/

public static boolean isValidImage(String imageUrl){
boolean isValid = false;
Pattern pattern = Pattern.compile("/images/slider/my");
Matcher matcher = pattern.matcher(imageUrl);
if (matcher.find()) {
isValid = true;
}
return isValid;
}


Then in your main function

if(isValidImage(imageUrl) {
//Do something here
} else {
//Add "/images/slider/my/" infront of the text
}


Use URLUtil to validate the URL as below.

URLUtil.isValidUrl(url)


It will return True if URL is valid and false if URL is invalid.

Another way is given below.

public static boolean checkURL(CharSequence input) {
if (TextUtils.isEmpty(input)) {
return false;
}
Pattern URL_PATTERN = Patterns.WEB_URL;
boolean isURL = URL_PATTERN.matcher(input).matches();
if (!isURL) {
String urlString = input + "";
if (URLUtil.isNetworkUrl(urlString)) {
try {
new URL(urlString);
isURL = true;
} catch (Exception e) {
}
}
}
return isURL;
}
