Reg.UUID class

[ldina...@gmail.com]

Hi [Dinakaran From India]

I bought Bluetooth TVSE Mobile Thermal Printer,

they given sdk and their sample apk.

There apk working fine.

In my codename one development, I am facing 

issue of UUID class missing while I am using their sdk for 

printing. 

After that I have gone through the net and came to know

that some of the java classes are blocked to control the

development size.

I need solution for the above issue mentioned.

Their sdk working in android studio, basically I am java

developer since 18years. So that I preferred codename 

one for app development. 

Now I am facing problem in UUID class in bluetooth printing.

I would suggest printing by generating an HTML file and firing up the browser using Display.execute. The browser would probably have access to the printer and can carry out the printing process for you. This will work on all platforms and should be simple to implement. Notice you can also generate images etc using the same approach.

If you need access to native system functionality you can do so with native interfaces but you would need to implement them for all platforms including iOS etc.: https://www.codenameone.com/how-do-i---access-native-device-functionality-invoke-native-interfaces.html

Sir,

Thanks for the reply, still I have doubt will share it.

App developed for bill collection by using sqlite db,

during collection would like to give receipt slip,

there is no internet connection either by wifi or 

data mode in the mobile. 

(INTERNET CONNECTIVITY ISSUE DUE TO BAD SIGNAL STRENGTH)

I want u to clarify, for that case also ur solution can support or not ?

Thanks, waiting for ur reply.

Sure. You will open an HTML file that's local to the device using a file:// URL. You need to create that file using the file system storage API which will also provide the URL you can execute.
