MCPE-7852<World> can't be opened
Fresh install of MCPE 0.10.4 on an Android tablet. Starts up ok. Click Play and then New. Enter details of World and click Create World!
Message displayed: "My World" can't be opened.
Tried every possible combination of settings but makes no difference.
Tried on similar tablet and it works ok. Examined tablet storage by connecting to a PC.
Looked in \games\com.mojang\minecraftWorlds
All the worlds that we tried to create had folders containing files.
However, none of these worlds are listed in the game when Play is clicked.
Did same on other tablet and noticed that there were more files in each created world.
Copied some of these worlds to the non-working tablet. Started MCPE and clicked Play. Now shows the copied worlds in the list. Selected a world but still got the "My World" can't be opened message.
Ran PocketMine server on my PC. Both tablets show the server world in the list and when selected, they both connect and work as expected.
Issue appears to be in creating/loading local worlds.

Both tablets are running Android KitKat 4.4.2 and the same version of MCPE (v0.10.4 alpha)
All updates applied as they have been released, and none of them came close to fixing the problem. Have got 0.13.0 now, and still can't open worlds.
Installed 0.11.0 alpha build 5.
Experiencing the same issue.
Copied in a world from another Android tablet on which MCPE works ok.
World appears in list (unlike locally created worlds)
When selected, Building world, Generating terrain message is displayed. (Didn't get this in 0.10.4 or 0.10.5)
Then "My world" can't be opened.
Therefore, not fixed in 0.11.0 alpha build 5.
Reopened, thank you Phil.
I am having the exact same issue with a tablet I just purchased. It is a no named brand from China. It fits the specs though to run the game. I installed the 0.11 alpha version after I found this issue and found that I could only connect to other hosted games on other tablets. What is the ETA on this fix?
[~rgreenly@gmail.com], this issue has not yet been fixed.
Is there a timeframe though when this will be addressed?
No, sorry.
Just FYI. I side loaded version 8 and it worked. So the problem lies between very.9-11. Something in there prevents worlds from loading.
From Shoghi Cervantes:
I am on V.011.0 alpha build 13 on two different generic tablets. One works fine, the other only can share into the world created by the other tablet. Is there something "hardware wise" that would prevent this, perhaps OS version?
-Rob Greenly
Will not open no files
I don't know if this makes a difference, but I think the tablet that we have on which MCPE doesn't work has been rooted. It was supplied from new like that, which seems a little odd for a tablet marketed for children.
Cleaning up old issues. If this bug still occurs in latest version, please leave a comment so we can reopen.
Updated to 0.12.2 alpha and it still doesn't work.
"My World can't be opened" as before.
Phil Rogers What is the world you are opening? Can you open any new world on this tablet/phone?
1) Cannot open any world created on this tablet, and they don't appear in the list of available worlds.
Folders for these worlds are created, but not fully populated. as I wrote in the description above.
2) Worlds copied from another (working) tablet appear in the available worlds list, but still can't be opened.
3) CAN open worlds via wi-fi that are running on another tablet. Not very convenient when you're on your own.
This bug has been very frustrating. Thanks for being so patient Phil Rogers.
To be honest, I can not reproduce this on any device I have ATM. What is the tablets you are using Phil Rogers?
The device is a 7" tablet running Android KitKat.
It is a Chimp Electronics Ltd tablet (I suspect it's a generic Allwinner tablet that they have re-packaged)
It is very similar to this one:
http://www.chimpelectronics.com/children-s-android-tablet.html
I have another tablet on which MCPE runs perfectly.
It looks physically identical to the first one and has a very similar specification, but was not supplied by Chimp.
My son is really unhappy about this. He received the tablet for Christmas last year and has been waiting for the fix for the last 10 months. As a professional software developer myself, I find it ridiculous that it still hasn't been fixed after all this time.
Resolved? Cannot reproduce?
This bug was raised almost a year ago and you've given up trying?
I'm sure you'll delete this comment, but it's not going to stop me from posting about it on social networks.
I am requesting a different tech take a look at this problem. Possibly a supervisor. This is ridicules! I have tried from my LG G4, and my LG Tablet. Both different carriers, but on the same wireless network. Same problem as everyone else.
Hi Phil Rogers and [~rgreenly@gmail.com], no we won't delete the comment and there are no supervisors or escalation of tickets in this system.
Phil Rogers I am still suspicious that your two devices may not be the same, especially if you believe one came to you rooted. I have tried to find an app that will export a list of all installed packages to a file so we can easily compare the two devices. Closest I have found is Stanley (Package Explorer) which allows me to see all installed packages in a list (including system packages and full names), but I cannot export it for machine comparison. You could put it on both devices, set its settings to show system packages and full names, then sort the packages alphabetically and scroll through both devices to see any differences. I have not search for this tool very thoroughly, I hope you can come up with something better.
The file system for saving minecraft worlds changed from version 0.9 and above. See: http://minecraft.gamepedia.com/Pocket_Edition_level_format. The failing device may have a conflicting library such as Zlib compression or LevelDB that is being used instead of the ones that are in MCPE. I do not know how to determine this. Phil Rogers have you tried installed a version of MCPE prior to 0.9 on the failing device to see if that works as was done by [~rgreenly@gmail.com]?
[~rgreenly@gmail.com], I am suspicious that there may be a piece of software on there conflicting. Can you provide details about what else you have installed after stock?
Happy to keep trying to help.
Also, although my expectations are low that this was fixed in the latest version, have either of you tried the latest beta testing build of 0.13.0? To see how to become a beta tester and receive the development builds for 0.13 go here.
I'm getting this same issue on v0.13.1 - The issue is exactly as described (Can't open world, can connect to worlds generated by other devices, can see worlds copied from another device but then fails to open them when copied locally). My nephew is pretty upset his chirstmas pressent still isn't working.
Device: tabl-it (https://www.besttabletcompany.co.uk/product/tabl-it-7/)
Android version: 4.4.4
Kernel version: 3.4.0+
Opening I found the following error:
games\com.mojang\minecraftWorlds\u0IAAE9cAAA=\db
I also appear to have an extra db folder:
games\com.mojang\minecraftWorlds\u0IAAE9cAAA=\db\db
Same isue here. Could u please take a look into this? Its kinda frustrating.
Divice is a Actions K700 tablet.
Android version 4.4.4
Kernel version 3.4.0
Same findings as above at Lindens post.
I suspect this bug happens on the cheaper tablets.
I am a Beta tester, so I get more updates and still nothing works.
I haven't tried a pre 0.9 version because I don't know how to get one. I only ever see the latest version on Google Play. No point in asking if I've tried an earlier version without telling me how to get one, is there?
Reopened.
I can confirm that this is also happening on my son's tablet. He has a BTC flame 7029C running Android 4.4.4. Kernel version is 3.4.0+
How soon do we think this Jira can be resolved and a patch / new software version issued? Or some kind of work around? Thanks.
I forgot to mention that he is using Minecraft PE 0.13.1 and cannot open any worlds locally.
this app was purchased, but never used because of this bug. no worlds ever created before, no new worlds can be created. for more than a month now, i have been rapped on the knuckles by various MOJANG mods for not following proper reporting protocol. so i've figured out that replies and comments are fast & furious for everything EXCEPT the issue at hand - "My World" can't be opened. This is a screenshot of my daughter's device. She got the device & app as a birthday gift, solely to play MC. Both are sitting useless on my desk for over a month.
Device is generic Android 4.4.4, with no other apps installed, and an added 16gb of storage.
Tired and frustrated of seeing this problems being discussed around in circles, but no solution.
Please confirm if this still affects 0.14.1
Just tried it on 0.14.1.
Still no luck. World cannot be opened.
Although we can connect to worlds on other devices, my 8-year old son has now given up with MCPE and has begun telling his friends what a load of rubbish it is because in the 16 months he's had it, he hasn't been able to play it standalone. He wants to know why Mojang keep working on adding new features but don't bother getting the basic game working properly.
Make sure the folder for minecraft saves isn't write protected, meaning (read only).
Does this affect the latest version? Please reply if it does.
Nearly 2 years since I reported this.
How do I get my money back?
The software is not fit for purpose.
If you're able to reproduce this issue in 0.16.0, please respond below.
nearly 1 year later, and still no resolution for me. <"My World" can't be opened > In fact, the app has now disappeared from my PlayStore account. I would purchase again, but not very confident! We tried for many months, 3 different devices ( 1 smartphone, 2 tablets). Zero support from Mojang. Apart from a generic message to say issue was 'resolved' - not for me!!!!
After years of not getting a resolution on this for my son's tablet, I now find that the latest version crashes on my phone, on which it has run without trouble for 2 years until now.
So, we have now written Mojang and Microsoft off as totally incompetent software developers who know only how to take peoples' money and run.
We have uninstalled the app from all of our devices, because it is just a big pile of crap.
Phil Rogers have you tried using a different device like what Device do you use for the game
I mean apparently you said it works with a different device plus they updated Minecraft a lot since then have you even tried lately
Joey Hollis.
After over 2 years of Mojang failing to fix this bug, we gave up with it. As a professional software engineer, I find it shocking that a company would not bother to get to the cause of the problem and fix it within that time.
Every time a so-called "fix" was released, it failed to work.
The Forum was full of people complaining about the problem, and even listed which models of tablet it didn't work on, but nobody at Mojang seemed to make the effort to obtain such a device to try it out.
Would it have been so difficult to buy a $42 tablet to investigate why it was failing? That's exactly what my company would do.
I even volunteered to run a special debug version that logged what was happening on my tablet, but nobody at Mojang took up that offer. Again, that's something else that professional companies would do.
And in answer to your question... Yes, I have tried it on other devices - one f which is identical in appearance to the one on which it fails (but has a quad-core CPU compared with a dual-core).
It also ran fine for about 2 years on my generic Android phone, until the last update, when after a couple of minutes it just randomly crashes back to Android with no messages, so I've uninstalled it from there now.
What really p*sses me off about it is that Mojang have been adding more and more functionality to the program without first making it stable enough to run on all hardware that it claims to support.
Get your act in gear. Forget trying to make it like the console version. Get it running properly first.
Thank you for your report!
However, this issue has been temporarily closed as Awaiting Response.
Is this still affecting the latest version? Several crash related issues have been resolved in the last few updates, as the developers have been working hard behind the scenes.
If you are still having this issue with any worlds, you may wish to upload a copy of your saved world for further investigation. We can't respond to every message individually but please be reassured we take your bug reports seriously and are grateful for the input.
