column '_data' does not exist

[tsptoni]

When I compile the app and execute in my tablet and I try to load an .obj object, it throws this error:

This is the part of the code responsible of this:

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 index = cursor.getColumnIndexOrThrow(column);
				return cursor.getString(index);
			}
		} finally {
			if (cursor != null)
				cursor.close();
		}
		return null;
	}

Any idea how to solve this?

Thanks

The app has been only tested loading files from file system, like sdcard.
What is your use case?

[tsptoni]

It loads an .obj file from the external SD Card on Android 7.0

[tsptoni]

The size of the file is 21,94Mb, may the problem is related with that?

[andresoviedo]

I don't think the size is an issue. Please be sure you are loading the file from internal or sd card memory

[andresoviedo]

Fixed in latest version.

[CodePoem]

Fixed in latest version.

How to fix it?Could you point the code, please?Thank you in advance.

[andresoviedo]

Hey. The latest version used a different API (ContentProvider) to read contents.
You can find the new implementation on ContentUtils.java. on method getInputstream()
