I need to know way for converting uri to string and string to uri.

Use toString() to convert a Uri to a String. Use Uri.parse() to convert a String to a Uri.

this code doesn't work

That is not a valid string representation of a Uri. A Uri has a scheme, and "/external/images/media/470939" does not have a scheme.

This will get the file path from the MediaProvider  DownloadsProvider  and ExternalStorageProvider  while falling back to the unofficial ContentProvider method you mention             Get a file path from a Uri  This will get the the path for Storage Access    Framework Documents  as well as the  data field for the MediaStore and    other file-based ContentProviders         param context The context      param uri The Uri to query      author paulburke     public static String getPath final Context context  final Uri uri         final boolean isKitKat   Build VERSION SDK INT  gt   Build VERSION CODES KITKAT          DocumentProvider     if  isKitKat  amp  amp  DocumentsContract isDocumentUri context  uri                ExternalStorageProvider         if  isExternalStorageDocument uri                 final String docId   DocumentsContract getDocumentId uri               final String   split   docId split                   final String type   split 0                if   primary  equalsIgnoreCase type                     return Environment getExternalStorageDirectory           split 1                                 TODO handle non-primary volumes                      DownloadsProvider         else if  isDownloadsDocument uri                  final String id   DocumentsContract getDocumentId uri               final Uri contentUri   ContentUris withAppendedId                      Uri parse  content   downloads public downloads    Long valueOf id                 return getDataColumn context  contentUri  null  null                        MediaProvider         else if  isMediaDocument uri                 final String docId   DocumentsContract getDocumentId uri               final String   split   docId split                   final String type   split 0                Uri contentUri   null              if   image  equals type                     contentUri   MediaStore Images Media EXTERNAL CONTENT URI                else if   video  equals type                     contentUri   MediaStore Video Media EXTERNAL CONTENT URI                else if   audio  equals type                     contentUri   MediaStore Audio Media EXTERNAL CONTENT URI                             final String selection     id                 final String   selectionArgs   new String                         split 1                              return getDataColumn context  contentUri  selection  selectionArgs                          MediaStore  and general      else if   content  equalsIgnoreCase uri getScheme               return getDataColumn context  uri  null  null                File     else if   file  equalsIgnoreCase uri getScheme               return uri getPath               return null            Get the value of the data column for this Uri  This is useful for    MediaStore Uris  and other file-based ContentProviders         param context The context      param uri The Uri to query      param selection  Optional  Filter used in the query      param selectionArgs  Optional  Selection arguments used in the query      return The value of the  data column  which is typically a file path      public static String getDataColumn Context context  Uri uri  String selection          String   selectionArgs         Cursor cursor   null      final String column     data       final String   projection                 column             try           cursor   context getContentResolver   query uri  projection  selection  selectionArgs                  null           if  cursor    null  amp  amp  cursor moveToFirst                  final int column index   cursor getColumnIndexOrThrow column               return cursor getString column index                   finally           if  cursor    null              cursor close              return null              param uri The Uri to check      return Whether the Uri authority is ExternalStorageProvider      public static boolean isExternalStorageDocument Uri uri        return  com android externalstorage documents  equals uri getAuthority                param uri The Uri to check      return Whether the Uri authority is DownloadsProvider      public static boolean isDownloadsDocument Uri uri        return  com android providers downloads documents  equals uri getAuthority                param uri The Uri to check      return Whether the Uri authority is MediaProvider      public static boolean isMediaDocument Uri uri        return  com android providers media documents  equals uri getAuthority

You can use Drawable instead of Uri       ImageView iv  ImageView findViewById R id imageView1      String pathName     external images media 470939       Drawable image   Drawable createFromPath pathName      iv setImageDrawable image     This would work

I am not sure if you got this resolved  To follow up on  CommonsWare s  comment   That is not a valid string representation of a Uri   A Uri has a scheme  and   external images media 470939  does not have a scheme   Change  Uri uri Uri parse   external images media 470939      to  Uri uri Uri parse  content   external images media 470939      in my case  Uri uri   Uri parse  content   media external images media 6562
