Please tell me how to solved this problem? but for the users not me
no
it’s a testing app
Yes that’s why your are receiving that warning, as you are directly installing the apk on your device.
Once you publish your app to playstore, then your users will not get such warning message when they will download it from playstore

but why the other apps ( not published on play store ) don’t get this alert ?!
Its just a warning and nothing more.
Just ignore it

As you can see, Play Protect didn’t recognise you. Play Protect thinks, you are unknown developer. Also other users maybe disabled Play Protect so that’s why they don’t see this alert.

ok , thank you and thanks for all 
Ha But what about those who don’t have a play store account
I mean Play store is not a safe place for testing your New Apps
a bit of mistake and Play Store will suspend your app and it will remain forever
Before getting fully ready you need to test your app by real users
Too many suspension and your Play Store Account will get terminated
and for entire life you will not able to make other Account + Its costly and It requires Credit card to Open a Account
Most of the people don’t have a Credit Card
I mean To buy play store account
I’ve checked the simplest of them and it works:
"The solution lies in creating a new key when generating the signed apk. this worked for me without a fuss.
- click on Build
- click generate signed Bundle/APK…
- choose either Bundle / APK (in my case APK) and click Next
- click on create new (make sure you have a keystore path on the machine)
- after everything, click finish to generate your signed apk
when you install, the warning will not come."
To do this, see e.g. here:
