Hi all,

my current B4A version is 6.80. Can I install V 8.50 over 6.80 or must I at first install all previous updates?

Thanx

Can I install V 8.50 over 6.80

yes

Make sure to use the B4A SDK MAnager and setup a new SDK (start with a blank folder, do not reuse an old SDK installation).

You can find the installation instructions here: https://www.b4x.com/b4a.html

I installed 8.50 over my 6.80. Compiled the first (big) program and get these:

What is wrong?

 

[DonManfred]

Unsupported major.minor version 52.0

what java version are you using?

 

[welu1805]

How do I get my version?

 

[DonManfred]

java -version

 

[welu1805]

java version 1.8.0_121

 

[DonManfred]

are you sure to use THIS version in the B4A IDE? Tools-Configure paths (javac path)

 

[welu1805]

In the IDE path was an older version. Now I have D:\Program Files\Java\jdk1.8.0_131\bin\javac.exe and it works!

Thanx
