Exclude imported resource-pack textures from Android photo apps

When Minecraft Bedrock imports a resource pack on Android, it should automatically prevent the pack’s PNG texture files from being indexed by Android Gallery and Google Photos. Resource packs can contain hundreds or thousands of PNG files. Android may treat these game textures as personal photographs, causing them to clutter photo applications and potentially be uploaded to the user’s cloud photo library. Minecraft could solve this by creating a ".nomedia" file in the parent resource-pack directory after successfully importing a pack, or by storing imported assets in a location that Android excludes from media indexing. Users should not need to edit the original ".mcpack" or ZIP archive. Altering the package may make it fail to import, and Android users often cannot access Minecraft’s protected storage directory afterward. This is also an accessibility issue. Players may depend on free community-made resource packs with simplified textures, stronger outlines, higher contrast, or clearer materials. The risk of flooding photo applications creates an unnecessary barrier to using those accessibility resources. This change would improve accessibility, privacy, storage organisation, and general Android usability.
