[Android]: TouchID not supported when testing on a device with fingerprint

Open e55o opened this issue 5 years ago • 11 comments

i am using:

    "react": "16.8.0",
    "react-native": "^0.59.3",

TouchID.isSupported() is always failing. I tried it on Samsung S8 and Huawei P10, both have fingerprint capabilities

They have fingerprints inserted in the cellphone database?

In my case, android devices returns 'true' if they have support. iOS returns 'TouchID' or 'FaceID'. I did an workaround to make it work properly checking this things. I don't know if it's the case of you.

Any solution?

@ligwang my answer above shows the solution... android returns true or false, ios returns TouchID or FaceID as literal strings... you just have to work with this returns.

Could you give me the solution?

As I do some work when TouchID is supported and other work when FaceID is supported. How am I supposed to differentiate between two of them if isSupported() always returns true rather than literal strings.

I don't know if the lib have a method to separate FaceID from TouchID. If you figure out to do this somehow, please comment the solution. Anyway, i don't know if there is another lib that can do a better implementation of fingerprint support...
