Did you try deleting the resource pack folder in your device's files? That worked with me in Update 0.15, and since your issue occurred after adding a texture pack, you might have the same situation.

If you are able, be sure to back up your world. You can do this by entering your device's files -> Device Storage -> games -> com.mojang -> minecraftWorlds. You will see a list of your worlds, but they will all be labelled in gibberish. (To see which world you are viewing, select that world, then select levelname.txt and you will see your world's name.) Choose which worlds you want to backup, and after "selecting" them, choose to "copy" them and "paste" them somewhere else on your device. Better yet, copy them onto your SD card if you have one, so then you can transfer worlds to a new device if you have to. This process will ensure that your world(s) are safe and can always be restored.
