How to extract the file name from URI returned from Intent ACTION GET CONTENT

Question

I am using 3rd party file manager to pick a file  PDF in my case  from the file system    This is how I launch the activity   Intent intent   new Intent Intent ACTION GET CONTENT   intent setType getString R string app pdf mime type    intent addCategory Intent CATEGORY OPENABLE    String chooserName   getString R string Browse   Intent chooser   Intent createChooser intent  chooserName    startActivityForResult chooser  ActivityRequests BROWSE     This is what I have in onActivityResult   Uri uri   data getData    if  uri    null        if  uri toString   startsWith  file               fileName   uri getPath          else      uri startsWith  content             Cursor c   getContentResolver   query uri  null  null  null  null            if  c    null  amp  amp  c moveToFirst                   int id   c getColumnIndex Images Media DATA               if  id    -1                    fileName   c getString id                                     Code snippet is borrowed from Open Intents File Manager instructions available here  http   www openintents org en node 829  The purpose of if-else is backwards compatibility  I wonder if this is a best way to get the file name as I have found that other file managers return all kind of things    For example  Documents ToGo return something like the following    content   com dataviz dxtg documentprovider document file 3A 2F 2F 2Fsdcard 2Fdropbox 2FTransfer 2Fconsent pdf   on which getContentResolver   query   returns null   To make things more interesting  unnamed file manager  I got this URI from client log  returned something like      sdcard downloads  bin    Is there a preferred way of extracting the file name from URI or one should resort to string parsing

First  you need to convert your URI object to URL object  and then use File object to retrieve a file name   try               URL videoUrl   uri toURL            File tempFile   new File videoUrl getFile             String fileName   tempFile getName              catch  Exception e                 That s it  very easy
