[Android]: TouchID not supported when testing on a device with fingerprint #221

Open e55o opened 5 years ago

e55o commented 5 years ago

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?

e55o commented 5 years ago

sure they have

lincolnbf commented 5 years ago

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?

lincolnbf commented 5 years ago

@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.

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...
