Android Question Firebase error

[elitevenkat]

The firebase project was working perfectly in my pc windows 7 with b4a7.8 platform-23.

i had installed b4a 7.8 in windows 10 64 bit. Followed all the instructions and installed all recommended sdk. The sdk installer had created platform 27.

when i try to run the firebase app, it throws the following error

I had reported this issue in the forum couple of days back. I did try the suggested solutions with out success.
I had reinstalled b4a couple of times.
Finally today i formatted my hdd and again installed b4a and sdk
Same old error.
Going back to my good old pc!!!

What is different to THIS thread? Or should i ask; Why are you creating two threads for the same issue?

@DonManfred and @Erel
my intention is not to create duplicate threads and i have never done that. I wanted to convey that, in spite of following all the referred possible solutions, re installing b4a couple of times and formatting and loading windows 10, i am not able to make it work.
Moreover in another system the same project is working perfectly. The only difference is in old system i had used platform 23 and now platform 27.
out of frustration and having tried various possible methods with out success, i posted it.
I am extremely sorry for that.
