From 4ceee3911a2ef567f614fc296475bc2b2a0e3add Mon Sep 17 00:00:00 2001 From: Bartlomiej Moskal Date: Mon, 21 Nov 2022 17:28:52 +0100 Subject: Android: fix Android assets handler not listing dirs with only sub dirs It looks like AAssetDir_getNextFileName is not enough. Directories that contain only other directories (no files) were not listed. On the other hand, AAssetManager_openDir() will always return a pointer to initialized object (even if the specified directory does not exists), so we can't just leave only it here. Using FolderIterator as a last resort. This approach should not be too time consuming. As part of this fix, add some unit tests to cover/ensure assets listing/iterating works as expected.
