Android Question Security Warning Triggered by B4X Application – Request for Clarification

[amarnath]

Recently, while using Kotak Mahindra Bank mobile banking services, I received the following security warning from the bank:

“Suspicious app deleted. They could compromise your data and passwords and leave you open to hacks. For your security, uninstall these apps.”

I suspect this warning may be related to an app compiled using B4X (B4A), even though the application is only used for development/testing purposes.

* Is code signing, target SDK configuration, or any manifest setting recommended to avoid such warnings?
* What best practices should developers follow to ensure B4X apps are not identified as potentially unsafe by banking applications?

Please guide me on how to resolve or prevent this issue.

Are you using "Kotak Mahindra Bank mobile banking services" from your b4a app ?
Or from Kotak Mahindra Bank mobile app ?

Kotak Mahindra Bank mobile app ?

Did it deleted your b4a app ?

Did it deleted your b4a app ?

No, it did not delete my B4A application.
The app is still working and B4A is properly installed on my device.

Maybe it's not detecting something in the app itself, but just that they are not installed through Google Play?

Or maybe another app is causing the message.

This is probably the case.

With that said, make sure to use your own private signing key instead of the default debug key.
