Android Question New B4a version migration problem

[LuigiTasca]

Hello,
I bought a new B4a licence for a new computer, but when I tried to copy my project into the new pc (from b4a version 7.30 to 8.30) I got this error:



Compilazione del codice Java prodotto. Error
javac 1.8.0_171
src\com\company\myapp\printspooler.java:17: error: cannot find symbol
ServiceHelper.StarterHelper.startServiceFromReceiver (context, in, false, BA.class);
^
symbol: method startServiceFromReceiver(Context,Intent,boolean,Class<BA>)
location: class StarterHelper

1 error


If I compile the code in debug mode it seems that it has problems with "wait for"


B4A line: 1420
Wait For (JR) JobDone(JR As HttpJob)

location: class DebugResumableSub

Can someone help me, please?

Did you setup a new SDK for B4A 8+?
It is recommended not to reuse an old SDK Installation.

You can find the Setup-Instructions here. https://www.b4x.com/b4a.html
You also can watch this Video as it describes it clearly.

Start with a new Blank folder like you see in the Video.

It looks like you are still using an old version of the core libraries. I recommend you to reinstall B4A in a new folder.

Ok thank you. If I reinstall b4a will I lose my licence?

 

[Erel]

No.
