Question

I have a String that can assume two forms

First form

 file:///mnt/sdcard/myfolder/myfile.txt

Second form

 /file://mnt/sdcard/myfolder/myfile.txt

And I need the String always in the form

/mnt/sdcard/myfolder/myfile.txt

So I have used the replace command

myPath=path.replace("file://", "");
myPath= path.replace("/file:/", "");

But unfortunately doesn’t work

and String myPath results

file:///mnt/sdcard/myfolder/myfile.txt

What is wrong?

Answer 1

If you’re guaranteed that your string will always be in one of those two forms, why not just use

myPath = path.substring(path.indexOf("/mnt"));

If you’re not sure your path contains “/mnt”, you could try this:

if (path.contains("file:"))
{
    myPath = path.substring(path.indexOf(":/") + 1);
    while (myPath.startsWith("//"))
        myPath = myPath.substring(1);
}
