Get the path from Uri in Android Kitkat throws Illegal Argument exception

Question

I'm trying to get the path from uri. it works in devices below kitkat. I googled and found that I need to get the document Id and then query it with the gallery items. And it works. But I'm facing problem with videos. When i select the video from Videos section, it works. But When I select it from Gallery, my app crashes, giving Illegal Argument exception- Not a document type. I know why it's happening. It is because I'm looking for a document type of video in Gallery section. But how to prevent this. So that I can select videos from both Gallery & Videos Section.

Here is my code:

public static String getRealPathFromURI(Context context, Uri contentUri,String type) {
    if(isKitkatBelow()) {
        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = context.getContentResolver().query(contentUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        return cursor.getString(column_index);
    }else{

        String docId= DocumentsContract.getDocumentId(contentUri);
        String id=  docId.split(":")[1];
        if(type== TYPE_IMAGE){
            String[] proj = { MediaStore.Images.Media.DATA };
            String whereClause=MediaStore.Images.Media._ID + "=?";
            Cursor cursor=context.getContentResolver().query(getUri(type),proj,whereClause,new String[]{id},null);
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        }else{
            String[] proj = { MediaStore.Video.Media.DATA };
            String whereClause=MediaStore.Video.Media._ID + "=?";
            Cursor cursor=context.getContentResolver().query(getUri(type),proj,whereClause,new String[]{id},null);
            int column_index = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
            cursor.moveToFirst();
            return cursor.getString(column_index);
        }



    }
}

This is happening because I'm trying to search a file of type MediaStore.Video.Media.DATA in Gallery. But for devices below kitkat, MediaStore.Images.Media.DATA gets the video uri, from the gallery too without causing any crash. Thanks in Advance..

You can use for getting absolute path from the Uri of selected file because of differences in both KitKat(API 19) and below Kitkat in android to achieve this using following code,

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

    final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;

    // DocumentProvider
    if (isKitKat && 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;
}
