What i have to do working good again ?

Reading the B4A 7 Setupguide.
You need to install Java 8

 

[Magma]

actually getting this and at new projects too...

May i have to install something or change something ?

Thanks in advance.

Did i wrote CHINESE?

You need to install Java 8

Notes:
- B4A compiled libraries with service modules need to be recompiled.
- Java 8 is required (Tools - Configure Paths).

sorry ...i didn;t refresh the browser

 

[Magma]

I ve already installed but i must change the path/folder at settings

 

[Magma]

Is it possible to remove older versions of java kits or i will have other problems ?

 

[DonManfred]

For B4A you dont need another java. But maybe another software on your pc depends on the old java. You need to check.
Usually you can remove older versions.
