Steps to Reproduce Bug

• Create new empty project
• Add Webstore. No event or anything.
• Preview via CocoonJS launcher on Android. (Galaxy S3 4.3)

Observed Result

Annoying alert message from CocoonJS. And I think Webstorage is broken.

On Ipad it is working fine.

Expected Result

Webstorage just work and no annoying message.

Affected Browsers

• Chrome: (NO)
• FireFox: (NO)
• Internet Explorer: (NO)

Operating System and Service Pack

Windows 8.1 64Bit

Construct 2 Version ID

R164.2 until R171. I just stopped and look for fix.

Solution is here http://docs.moodle.org/24/en/Converting_files_to_UTF-8

Just open the files from webstorage plugin folder in Notepad++ and resave as UTF8. I noticed that the runtime.js is in "UTF8 without BOM" format. So that may be the cause of the problem.

Hopefully this help anyone that having this problem and I hope you included the fix in next release.

I can't figure out why this happens. It must be a CocoonJS bug, please report it to Ludei. Look how it says it's first evaluating it as UTF-8 then says it actually loaded it with ISO-LATIN-1. There's no reason for it to use that encoding, all C2 scripts are already encoded with UTF-8, so it must be loading it wrong and corrupting it within CocoonJS.

Like I said, I found that runtime.js is in "UTF8 without BOM" in NotePad++. While others are actually in "UTF8" when you click the Encoding tab. Maybe it is the one that causes the problem? I found out that I`m not the only one with this problem in the CocoonJS thread.

It is kinda strange though since I did manage to upload one game last month using R167.2 but when I did downgraded the preview still got the same error. I think they maybe did something to the Launcher and make it incompatible with that format or something.

Anyway the "fix" or solution is quite simple and strange though. And I think you know they will just ignore my complaints

tumira - I tried changing it to UTF-8 (with BOM) and it didn't fix it, at least on Android 4.4.2. I'm pretty sure it's a bug Ludei need to fix.

Does this happen with an actual CJS compile for you or only preview? I just did mine with R171 and using all 3 versions of the CJS compiler: 1.4.7, 2.0.0 and the latest 2.0.1 and my WebStorage saving works fine.

I have installed C2 R172 today and the bug came back. You are right , its not about the runtime.js UTF8 with or without BOM.

The bug is in common.js. I just do this.

1)Copy common.js to desktop (since you cannot edit and save in Program Files)

2)Open common.js in Notepad++

3)Press spacebar in the editor

4)Save

5)Copy and replace back to webstorage plugin folder.

I've tested in CocoonJS Launcher v2.0.1 via preview with empty project+webstorage and the solution works. Strange right ?

The file is actually just empty file (with space). I've attached the file if you want to test.

I've tested preview using wifi on Android 4.3 Galaxy S3. On Ipad4 the bug does not happen. Do you test on IOS or Android ? This bug is kinda strange but as you can see Ashley also effected with this bug. So it is not just me.

Same here. I can't reproduce this issue. But I have copied the exported cocoonjs file on my Android Device via USB. I don't get any errors with the webstorage. Try the same and copy your cocoonJS file directly on your device via USB (Root folder).

I also use r171, WebStorage and CocoonJS plugin 2.0 (latest version) and I have no problems. Not in Preview and not after compiling it.

Thank you for your posting. What OS are you using ? I`m using Windows 8.1 64 Bit.

This bug is kinda strange, Ashley got it, I also have this bug and some guy at the CocoonJS thread also asked something about this bug since he also encountered it.

For me, my solution seems to work. I just do what I mentioned above.

I also use Win 8.1 64 bit and I also have figured out the problem. It's the "Minify Script" process during the export. Uncheck this and you get no error

AndreasR

Good to know. I try to uncheck minify script if my game have problem after exported.
