Take thumb impression android

To my knowledge this can't be done. Capacitative screens (which would detect a thumb) are not sensitive enough to get a fingerprint. Cool idea though... Maybe consider using the camera (though it would have to be pretty high quality).

I can suggest you one alternative rather than taking finger print .. There few apps developed on android which basically recognizes your pressure not your fingerprint and it resembles that they are taking your finger print.

Have a look at it.. I don't know if it solves your problem. !

Android does not do fingerprint recognition. If you are talking about those apps that "claim" to do it by you holding your finger against the screen ... its a bit of a con. They don't really scan your finger print ... they are just testing area and pressure (if that).

First, don't ask for code. This place is not for giving out code but snippet or help. You're asking for someone to publish complex code here...that's ridiculous.

Second, if there was a library available for FingerPrint recognition. I highly doubt you could even do anything with it. Why?

Phones don't have hardware to capture fingerprints. A screen cannot capture images but only pressure levels and they aren't really accurate too. The camera on the phone cannot capture macros unless you mount a microscope lense.

So if you really want my advice, give up on it. With the current hardware available it is not coming soon to android. When there will be hardware I believe there will be an api provided for it.

What you can do on the other hand is voice recognition, face recognition. I don't have any idea how it can be done but the hardware is there. You could even make a hand recognition.

Finger prints forget it.
