Sorry, correct is "i downloaded this electrum from google play. I check it twice.
Well, as hosseinimr93 pointed out, that address appears to belong to a hacker/scammer. It's unlikely your seed phrase was compromised, but it's very likely you did not install the official Electrum app from google. I know you were trying to be careful, but at this point it's the most likely scenario. You can check your google account to see which app you have installed, and compare it to the app to which official Electrum website directs.
Here's the official website link:
https://electrum.org/#homeAnd, the link to the official app on google play:
https://play.google.com/store/apps/details?id=org.electrum.electrumIf you have the real app installed the play store will inform you as such:
