Android M fingerprint scanner on Android Emulator

问题:

I want to ask how should I test my fingerprint authentication on Android Emulator?

I was trying to use

adb -e emu finger touch [finger_id]

referred from link here but it seems to be not working with my Emulator.

My Emulator is Targeting API 23, Android 6.0, x86_64.

Any help will be appreciated.

Thanks

You can do it from Emulator itself

Go to Settings -> Security--> Set a device lock methos-->Create a pattern

Then click on FingerPrint to register some fingerprints

Now You can use fingerprints from emulator settings as shown in pic below

Hi you have to connect to Telnet even if you're using Mac:

telnet 127.0.0.1 5554

then enter the cmd to authenticate

auth yourtoken

your authentication token is in this file '/Users/yourname/.emulator_console_auth_token'

then you have to register the finger print before to use the command. So go in Settings -> Security -> Fingerprint -> Add fingerprint and launch the command on terminal

finger touch 1

Now your fingerprint with ID 1 is enrolled and you can use it to authenticate

Adding to above answer of "br00"

If you are using Windows then please do below steps.

1.) Check if you have telnet installed or not. Simply run "telnet" command in cmd prompt. If it say command not found. Then install telnet using below link:

For me its simply in Windows 7

pkgmgr /iu:"TelnetClient" in command prompt

2.) Run emulator and check its id. Emulator id usually appears in title bar of Emulator. :5554 So id is 5554

3.) Enter below command in cmd prompt

telnet 127.0.0.1 5554

4.) Add auth token in telnet window:

auth "yourtoken String"

Usually you will find auth token at below path

'/Users/yourname/.emulator_console_auth_token'.

Just open the file and copy the token and pass it in above command in telnet window

5.) then you have to register the finger print before to use the command. So go in Settings -> Security -> Fingerprint -> Add fingerprint

Now open your telnet session command window and enter following command:

finger touch 1

Now your fingerprint with ID 1 is enrolled and you can use it to authenticate

6.) Repeat step 5 if you want to add multiple finger print. But make sure you always add new finger print id. Here is 1 in step 5.

7.) Now when you want to authenticate just use below command in telnet window:

finger touch 1

That's It

follow these steps:

1. Install Android SDK Tools Revision 24.3, if you have not done so.
2. Enroll a new fingerprint in the emulator by going to Settings > Security > Fingerprint, then follow the enrollment instructions.
3. Use an emulator to emulate fingerprint touch events with the following command. Use the same command to emulate fingerprint touch events on the lockscreen or in your app.

adb -e emu finger touch

On Windows, you may have to run telnet 127.0.0.1 followed by finger touch

It works as follows:

telnet 127.0.0.1 5554 followed by finger touch 1 for instance. You can give any random number to test it out.
