Android Question B4A 7.00 & major.minor version 52.0

[luke2012]

Hi All.
I'm happy to receive the new version of B4A (from @Erel).
After installed the new version I got an error while compiling my existing projects (using the old version all was ok):

B4A version: 7.00

Any Idea to solve this issue with the new version ?

Have you updated your java SDK? It now needs version 8 if not mistaken

You are correct.

See https://www.b4x.com/android/forum/pages/results/?query=major.minor+version+52.0

You are correct.

See https://www.b4x.com/android/forum/pages/results/?query=major.minor version 52.0

Thanks for your help I check and I have the C:\Program Files\Java\jdk1.7.0_79\bin\javac.exe in the ide path.
So I have to upgrade java sdk.

Sorry. Now I see that in the Erel post there was the instruction to installa java 8.

What about versione 7.01 ? I received the official mail to download versione 7.00 but not 7.01. It's a bug fix version?

Yes. Just re-download the Setup from the link you know if you already downloaded v7.0

I think this would have gone far better if erel would have put in an alert to tell you to install Java 8 when you attempted to compile with Java 7 or earlier. Instead of dumping out cryptic data that nobody understands and I see these threads over and over again... But thats my 2 cents.
