This has been happening to me for some unknown reason, it says that my texture pack has a missing name, even though I followed the tutorial exactly. Can someone help me? This is the first time I made a Minecraft Pocket Edition 1.2.10 Texture Pack. Also, you may see another post that is similar to this one, by me, but please just ignore that post.
After checking the version of Minecraft pocket edition, I have realized I made a mistake. It is version 1.2.10, not version 1.12.10.
