I have had a similar problem with a survival world...The only thing that would fix it was...well deleting the world, what you might try to avoid that is to download Astro file manager. Or something else like that, and copy your world. If neither copy works, you can try something like what Dblcut3  said, since you have an android, try Getting astro and saving your worlds to a ¨Zip¨ file, then email them to yourself through an attached G-mail and then, delete the app, redownload, and open your e-mail. Then it's a simple matter of bringing back and unzipping files. (WARNING: If you accidentally delete something good, you could mess up your phone, so be VERY careful)
