Re:Google signin returns 12500, 12501 error code

in my case keystore's SHA-1 was not included in project on google developer console and google-services.json

How to get SHA-1:

on MAC
path/to/keystore ==

on Window
path/to/keystore ==
C:\Documents and Settings\[USER NAME]\.android\debug.keystore

keytool is in
C:\Program Files\Java\jdk1.7.0_79\bin
or whatever jdk version you have

Run the following command on terminal/command-prompt
keytool -list -v -keystore  path/to/keystore

above command will print something like this

Alias name: androiddebugkey 
Creation date: 10 Dec, 2015 
Entry type: PrivateKeyEntry 
Certificate chain length: 1 
Owner: xxxxx 
Issuer: xxxxx 
Serial number: xxxxx 
Valid from: Wed Dec 09 20:20:53 IST 2015 until: Sun Dec 02 20:20:53 IST 2040 
Certificate fingerprints: 
	 MD5:  XX:XX:XX:XX 
	 SHA1: 12:34:56:78:90:AB:CD:EF:12:34:56:78:90:AB:CD:EF:AA:BB:CC:DD 
	 Signature algorithm name: XXXXXX 
	 Version: 3

copy the SHA1: XXXXX value (only XX:XX:XX... value without "SHA1:") where Alias name == androiddebugkey

now go to and open your sign in app and add a new Credentials -> OAuth Client ID

Application type == "Android"

and put this XX:XX.. value into form and fill package name in form and save it

then add same SHA1 value into google-services.json as bellow

"oauth_client": [ 
          "client_id": "",// newly saved client id on 
          "client_type": 1, 
          "android_info": { 
            "package_name": "com.example.myapp", // your app's package name 
            "certificate_hash": "1234567890ABCDEF1234567890ABCDEFAABBCCDD" //XX:XX:XX value without :
