Issue
How can I get the name of a file from a uri
returned in OnActivityResult
,
I tried using this bit of code
Uri uri = data.getData();
String fileName = uri.getLastPathSegment();
but it just returns something like this images:3565
. The file that is picked is not only of image type it can be a video, or document file, etc.... I realized that the uri returned from kitkat is different than previous versions as well, I would be interested in a method that works for pre kitkat as well.
Solution
This is the code I'm using to get informations from a Uri :
public static class FileMetaData
{
public String displayName;
public long size;
public String mimeType;
public String path;
@Override
public String toString()
{
return "name : " + displayName + " ; size : " + size + " ; path : " + path + " ; mime : " + mimeType;
}
}
public static FileMetaData getFileMetaData(Context context, Uri uri)
{
FileMetaData fileMetaData = new FileMetaData();
if ("file".equalsIgnoreCase(uri.getScheme()))
{
File file = new File(uri.getPath());
fileMetaData.displayName = file.getName();
fileMetaData.size = file.length();
fileMetaData.path = file.getPath();
return fileMetaData;
}
else
{
ContentResolver contentResolver = context.getContentResolver();
Cursor cursor = contentResolver.query(uri, null, null, null, null);
fileMetaData.mimeType = contentResolver.getType(uri);
try
{
if (cursor != null && cursor.moveToFirst())
{
int sizeIndex = cursor.getColumnIndex(OpenableColumns.SIZE);
fileMetaData.displayName = cursor.getString(cursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
if (!cursor.isNull(sizeIndex))
fileMetaData.size = cursor.getLong(sizeIndex);
else
fileMetaData.size = -1;
try
{
fileMetaData.path = cursor.getString(cursor.getColumnIndexOrThrow("_data"));
}
catch (Exception e)
{
// DO NOTHING, _data does not exist
}
return fileMetaData;
}
}
catch (Exception e)
{
Log.e(Log.TAG_CODE, e);
}
finally
{
if (cursor != null)
cursor.close();
}
return null;
}
}
