java - Having issue with file path

I am successfully able to select file programmatically. But, when I am getting uri from that file

content://com.android.providers.downloads.documents/document/3356

content://com.android.providers.downloads.documents/document/3331

Unfortunately, wherever the file is my uri is always locating at downloads.documents

I think it doesn't fact. Cause, everyone get the uri by data.getData(). So, I think the uri is correct.

Last year, I was working with Audio, Video, File and Image uploading to server. I was trying that source code to get path.

String mediaPath, mediaPath1;
String[] mediaColumns = {MediaStore.Video.Media._ID};
// Get the file from data
            String path = data.getStringExtra(mediaPath);
            File file = new File(path);
            Uri selectedFile = Uri.fromFile(new File(file.getAbsolutePath()));
            String[] filePathColumn = {MediaStore.Files.FileColumns.MEDIA_TYPE};

            Cursor cursor = getContentResolver().query(selectedFile, filePathColumn, null, null, null);
            assert cursor != null;
            cursor.moveToFirst();

            int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
            mediaPath = cursor.getString(columnIndex);
            txt.setText(path);
            // Set the Image in ImageView for Previewing the Media
            cursor.close();

Unfortunately,That is returning null pointerexception. After researching little bit, I found another source code(PathUtils)

public class PathUtils {
public static String getPath(final Context context, final Uri uri) {

    // DocumentProvider
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && DocumentsContract.isDocumentUri(context, uri)) {

        if (isExternalStorageDocument(uri)) {// ExternalStorageProvider
            final String docId = DocumentsContract.getDocumentId(uri);
            final String[] split = docId.split(":");
            final String type = split[0];
            String storageDefinition;


            if("primary".equalsIgnoreCase(type)){

                return Environment.getExternalStorageDirectory() + "/" + split[1];

            } else {

                if(Environment.isExternalStorageRemovable()){
                    storageDefinition = "EXTERNAL_STORAGE";

                } else{
                    storageDefinition = "SECONDARY_STORAGE";
                }

                return System.getenv(storageDefinition) + "/" + split[1];
            }

        } else if (isDownloadsDocument(uri)) {// DownloadsProvider

            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);

        } else if (isMediaDocument(uri)) {// MediaProvider
            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);
        }

    } else if ("content".equalsIgnoreCase(uri.getScheme())) {// MediaStore (and general)

        // Return the remote address
        if (isGooglePhotosUri(uri))
            return uri.getLastPathSegment();

        return getDataColumn(context, uri, null, null);

    } else if ("file".equalsIgnoreCase(uri.getScheme())) {// File
        return uri.getPath();
    }

    return null;
}

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 && cursor.moveToFirst()) {
            final int column_index = cursor.getColumnIndexOrThrow(column);
            return cursor.getString(column_index);
        }
    } finally {
        if (cursor != null)
            cursor.close();
    }
    return null;
}


public static boolean isExternalStorageDocument(Uri uri) {
    return "com.android.externalstorage.documents".equals(uri.getAuthority());
}


public static boolean isDownloadsDocument(Uri uri) {
    return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}

public static boolean isMediaDocument(Uri uri) {
    return "com.android.providers.media.documents".equals(uri.getAuthority());
}

public static boolean isGooglePhotosUri(Uri uri) {
    return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
}

I am not getting any error. But, Path is always locating at Downloads file. I don't know why. After looking at uri I noticed my uri is always returning downloads.documents. I am not sure is it the issue.

There is lot of question similar to this question in stackoverflow. To tell everyone none worked for me. So, I will request to not flag it.

PATH: /storage/emulated/0/Download/The Road to Reality ( PDFDrive ).pdf

PATH: /storage/emulated/0/Download/The order of time ( PDFDrive ).pdf

PATH: /storage/emulated/0/Download/pdf_495.pdf

First pdf file is in documents file. Second pdf file is in Download third pdf file is in /storage/emulated/0/
