NoSuchMethodError No Direct Method

[Gareth Murfin]

I compiled and sent this project to the server https://github.com/chen-fishbein/bluetoothle-codenameone/tree/master/BTDemo

It runs fine but when I tap "initialise" I get this error

"no such method error, no direct method java/util/map in class ca/weblite/codename1/json/JSonObject

Any ideas?

[Gareth Murfin]

Seems like it should be due to no json lib, but its there, then I realised it was only 30k somehow soI grabbed it from here

https://github.com/codenameone/CodenameOneLibs/tree/master/cn1libs

that one was 85k... but now it wont compile  (complains that it cannot find ca.weblite.codename1.json.JSONObject; ) , even after doing refresh cn1 libs. I cannot work out whats going wrong ive used the json lib hundreds of times with no issue.

[Gareth Murfin]

oh I forgot to delete the folder in the libs dir, I think that was why, all good now. 

[Gareth Murfin]

actually on the device im still getting the error, im very confused right now, any thoughts??

Hi Garet

I used the BlueThooh codename one lib and didn't have any problem. The project work fine for me. I added the BT and Json Required Libraries from Codename One Settings (libs option).

This are my libs size

C:\dev\eclipseOxigen\OxigenApp\lib>ls -la

total 18736

Thanks very much for your reply Kandy.

They look similar (though) not exactly the same as mine.. where did you get CN1Bluetooth.cn1lib from? im using theirs which as you can see has a spelling mistake, so yours might be different?

Hi Gareht

You haven´t all the required libs, You must import the Json CN1JSON.cn1lib.

I recomended you, clean your libs and reimport it.

I importd directly from codenameOne Preferences, I use Eclipse. Whai Ide you use?

Just see this links:

https://www.codenameone.com/cn1libs.html

https://www.codenameone.com/manual/advanced-topics.html#_libraries_cn1lib

Best Regards Kandy

[Gareth Murfin]

I do have that library if you look carefully. I have tried cleaning and reimporting many times... seems ok on the emulator (ie json lib works) but on phone it always has that error.

Notice that there is more than one json lib...

[Gareth Murfin]

That's confusing. Weirdly I was trying to make a change to the bluetooth lib but then when I try to use it I get the same error. about missing method etc...once i compile it. hair tearing madness.

[Thomas]

you probably forgot to click on "Refresh CN1 libs" after replacing the old .cn1lib file in your project with your modified one.
