google SignIn in android getting Invalid SHA-1 certificate fingerprint error

I want to integrate google SignIn to my android app. I have followed all the steps as per the documents. i have created a cerificate finger print through cmd using the following command.
keytool -list -keystore C:\Users\ufxyhy\.android\debug.keystore
I have entered the password when it prompted and then I got a key showing as SHA-256, and it shows as invalid fingerprint when creating OAuth client ID.
The result I am getting in cmd is follows
Keystore type: JKS
Keystore provider: SUN
Your keystore contains 1 entry
androiddebugkey, 18-May-2018, PrivateKeyEntry,
Certificate fingerprint (SHA-256):
00:00:****************:00:00:00:00:00
It shows as SHA-256, How can I create correct SHA-1 finger print for debug?

you can get SHA1 with follow command
keytool -list -v -keystore {keystore_name} -alias {alias_name}
eg:
keytool -list -v -keystore C:\Users\me\Desktop\release.jks -alias sample
you can also get it in android studio directly as in image

You need to provide default keystore password and key password which you have not provided run below code and check.
keytool -list -keystore C:\Users\ufxyhy\.android\debug.keystore -alias androiddebugkey -storepass android -keypass android

Google map reporting invalid key in Android

I got the SHA-1 fingerprint from using the keytool for my application on my key that I sign the application with when I upload it to the play store.
But when I open the app on my phone for testing it says it is not the right key. ANy ideas what I could be doing wrong?
Not sure what more information i can give without giving security info for my app, so if you can help give me anymore information that I can not think of please let me help you help me.

First for the development generate a SHA-1 from debug.keystore:
Navigate to C:\Program Files\Java\jdk1.6.0\bin>..... where your bin located then execute below command
C:\Program Files\Java\jdk1.6.0\bin>keytool -v -list -alias androiddebugkey -keystore "D
:debug.keystore" -storepass android -keypass android
or
C:\Program Files\Java\jdk1.6.0\bin>keytool -v -list -alias androiddebugkey -keystore "C:\Documents and Settings\user1\.android\debug.keystore" -storepass android -keypass android
Now, you can get one SHA-1 certificate and generate API key from Google API console. Add this key into your manifest.xml file. remember this API key only for the development. Using this key built apk u can not publish into market.
Now, turn to make your own keystore: execute below command
C:\Program Files\Java\jdk1.6.0\bin>keytool -genkey -v -keystore OWN.keystor
e -alias ALIASNAME -keyalg RSA -keysize 2048 -validity 300000
and give all the required details for this keystore. Now time to generate SHA-1 from your OWN.keystore execute below commnad
C:\Program Files\Java\jdk1.6.0\bin>keytool -v -list -alias ALIASNAME -keystore "C:\Program Files\Java\jdk1.6.0\bin\OWN.keystore" -storepass PASSWORD -keypass KEYPASSWORD
Now, you can get one SHA-1 certificate and generate API key from Google API console. Replace this key into your manifest.xml file. Now your app is ready to publish into market.
This may helpful to you.

Have you tried to completely remove the application and then install it all over again. This key might be got cached and even if you install the application with new key.
So before you install your application with the new key, try to remove the application completely from the phone.
You can as well go over this blog post I wrote and make sure you do all the steps right in producing the key:
Google Maps API V2 Key

Invalid fingerprint for generating Google Map key for android application

I have successfully generated the fingerprint Certificate for google map key by using these command
keytool -list -alias androiddebugkey -keystore "C:\Users\pc\.android
\debug.keystore" -storepass android -keypass android
and i got this result
androiddebugkey, Aug 25, 2012, PrivateKeyEntry,
Certificate fingerprint (SHA1): 68:1F:B8:80:C0:B9:96:D1:6E:95:86:69:CD:DB:0E:28:DC:9E:89:51
when i try to register Certificate fingerprint on this site https://developers.google.com/android/maps-api-signup
page replied me The fingerprint you entered is not valid. Please press the Back button on your browser and enter a valid certificate fingerprint
where is problem please help.

I find the solution of my problem just changed the command by this
keytool -list -v -alias androiddebugkey -keystore C:\Users\<user>\.android\debug.keystore -storepass android -keypass android

If your having issues finding the debug key path or dont want to use the adb you can get the fingerprint in eclipse:
go to window-->preferences and find the android section. Select the build sub-setting.
for the production fingerprint when your exporting your signed application using ADT right before you click finish the hash will be there. just copy it.

Map key generate issue on android

i get knowledge from http://mobiforge.com/developing/story/using-google-maps-android.
i get fingerprint key from my machine.
I use below command :
keytool.exe -list -alias androiddebugkey -keystore "D:\Android\Key Store\debug.keystore" -storepass android -keypass android
Certificate fingerprint (SHA1): FB:8E:56:83:06:C6:AA:39:56:A8:04:DD:0F:ED:3E:71:BD:8A:3A:4A
But when i put on google map api, it throws "The fingerprint you entered is not valid. Please press the Back button on your browser and enter a valid certificate fingerprint. "
If i give "FB:8E:56:83:06:C6:AA:39:56:A8:04:DD:0F:ED:3E:71" only google generate Map key. But its not woking on my device.
pls help me wtats the problem and how to generate map key.

With Windows 7 installed, keytool outputs by defaultSHA1 fingerprint, not MD5. Adding -v option allows to see MD5 as well.
list -alias androiddebugkey
keystore "C:\android\debug.keystore"
storepass android -keypass android
-v for verbose..
All the best

Obtaining Google Maps API key

I'm using Windows 7.
I have tried several times with the debug.keystore with appears in c:\users\YOURUSER.android\ using the command:
keytool -list -alias androiddebugkey -keystore c:\Users\YOURUSER\.android\debug.keystore -storepass android -keypass android
It gives me a MD5, but then I go to Google MD5 registration page and it sais it is not a valid fingerprint.
I searched for more information, and I finally created a new debug.keystore into c:\users\YOURUSER\ to avoid rewriting the original one. I used this command:
keytool -genkey -keypass android -keystore c:\users\YOURUSER\debug.keystore -alias androiddebugkey -storepass android -validity 10000 -dname "CN=Android Debug,O=Android,C=US"
It works, so I use the previous command to get the MD5, and it gives me a new MD5. Then I go to Google again and the same problem: "not a valid fingerprint".
The I made a second attempt. This is what I did then:
1) Opened a Windows7 terminal, went to c:\program files\java\jdk1.7.0\bin\
2) Wrote command:
keytool -genkey -v -keystore c:\eclipse\my-release-key.keystore -alias alias_name -keyalg RSA -keysize 2048 -validity 10000
3) Then I tried to get the MD5 code from my keystore, using comand:
keytool -list -alias alias_name -keystore c:\eclipse\my-release-key.keystore
and writing the password I am asked. It gives me a MD5.
4) I go to maps api key sign up and write the MD5. "FINGERPRINT NOT VALID"
I don't know what the problem is. And I am supposed to do this for every app I program? What a headache!
Can anybody help me please?

Are you sure you get the MD5 and not the SHA1 fingerprint? Tryed the -v option?
see: How can I get the MD5 fingerprint from Java's keytool, not only SHA-1?

google maps has deprecated its previous version API v1 and introduced a new version of google maps API v2.
previously we generated md5 key but now we need to generate sha-1 fingerprint certificate.
The Maps API key is based on a short form of your application's digital certificate, known as its SHA-1 fingerprint. The fingerprint is a unique text string generated from the commonly-used SHA-1 hashing algorithm. Because the fingerprint is itself unique, Google Maps uses it as a way to identify your application.

How to implement Google Maps new version of API v2

In command line you need to open Java-> jdk-> bin
as for me it is "C:\Program Files\Java\jdk1.7.0_03\bin"
There is "keytool" program which u need. In command line enter "cd C:\Program Files\Java\jdk1.7.0_03\bin"
And enter "keytool -list -v -keystore C:\Users\John\.android\debug.keystore"
So the final string in command line must look like:
"C:\Program Files\Java\jdk1.7.0_03\bin>keytool -list -v -keystore C:\Users\John\.android\debug.keystore". Whare usually u need only to change the name "John"
There will be SHA-1, MD5, etc
Finally, go to Google Access API google access api
