是否有 API/库将返回 Android 应用程序的身份验证级别

Question

I'm currently writing an android app where I use PackageManager to get all of the installed applications on the device. I want to order them in a recyclerView based on their level of authentication (if they require a fingerprint, passcode, or facial recognition to use). Is there any library or API out there that can get me close to something like this?

Thanks!

No. You can use PackageManager to see what apps request the USE_FINGERPRINT or USE_BIOMETRICS permissions. However:

• You have no idea to what extent the app is using those permissions

• That may not cover device-specific proprietary SDKs (eg, Samsung's)

• You have no way of determining if an app requires a password or other forms of authentication
