If you use:
keytool -genkey -v -keystore testapp.keystore -alias testapp -keyalg RSA -validity 999999
to generate the keystore, you would then use:
keytool -exportcert -alias testapp -keystore testapp.keystore -list -v
to get the SHA1 value. Of course you have to be in the same folder that you were in when you created the keystore.
@corona208, as Rob noted above, the -alias should be followed by the path to the alias and -keystore should be followed by the path to the keystore. If you have not moved your keystore to any folder on your mac but left it on where it was generated, you don’t need to add ~/. in front of the keystore.
About the fully working sample code for GPGS with leaderboard and achievements, you can find it here:
https://github.com/coronalabs/plugins-sample-gameNetwork-google
Edit: A quick not to mention that you need to insert appropriate IDs from Google Play (because the sample code does not include them.) It won’t just work without inserting correct value.

Hi Naomi & Rob,
I track the error but not find solution still. when i run this command
https://developers.google.com/games/services/android/troubleshooting
“unzip YourGame.apk”
key tool -printcert -file META-INF/CERT.RSA
CERT.RSA file not generate in apk. Therefore SHA1 mismatching and gives sign-in error. I trace the error with the help of eclipse. I also make the apk with the help of eclipse. In eclipse apk generate all files. but corona apk generate all files except CERT.RSA
simple to say, In corona SDK apk CERT.RSA file is missing only.
anybody have solution of this problem? please share it
Hi funkyvisions,
how you get rid of this error. how your SHA1 are matched. when i used production/release key it create the apk successfully. when i extract the file from using this command
unzip YourGame.apk
keytool -printcert -file META-INF/CERT.RSA
https://developers.google.com/games/services/android/troubleshooting
CERT.RSA file not create in corona apk so my SHA1 not match so therefore i face the problem the sign-in problem i think so you also face the same problem of SHA1. if you have any solution about this problem please help me
w8 for your reply
A big THX to Naomi
it works now (my fault was that the app name and the keystore was not the same). sometime fingers are faster than the brain!
for all, if you like to restart the OAuth2 procedure the only way i found, was to delete the app in the google play game service and recreate a new entry with all the parameters, copy the new ID to your build.settings and make a new version.

Hi, I am having the same problem and seems you have a solution, my question is what do you mean by “had to go back and make sure I checked “This app is preferred for new installations.” for the entry I was using.”
Hi funkyvision, can u help me about Google Play Game Services sign-in problem. This type of error show on my android device “there was a sign-in issue.” I implement all things correctly in correct place but error not finish. How i remove this error. if u send me ur own sample code of only GPGS whose full fledge functionality and error free…m really thankful to you…
I also check this link but it gives the same error of sign-in problem…
https://github.com/coronalabs/plugins-sample-gameNetwork-google
Does it work for everyone now? Thought I’d share the lessons I learned in case it helps anyone else. I didn’t read everything above so I hope I’m not boring people. Anyway lessons learned:
XXXXXXXXXXX.apps.googleusercontent.com
but when you remove the client ID and the linked app from the dev console and redo the process again the api console will show a client ID in the following format instead:
XXXXXXXXXXX-YYYYYYYYYYYYYYYYYYYYYYYYYYYY.apps.googleusercontent.com instead. Stupid bug Google…!
Well, now it will work! Unless:
Hope this helps someone! I spent the better part of this day to get this to work. Finally got the plugin sample going just a few minutes ago!
I had the same error, but got this resolved – at least now I’m logged in to game service, and can see my Leader Board.
I looked at this article, and found my SHA1 certificate fingerprint
https://developers.google.com/games/services/android/troubleshooting
You can find yours with this command:
keytool -exportcert -alias androiddebugkey -keystore debug.keystore -list -v
Just replace “androiddebugkey” and “debug.keystore” with the name and filename of your keystore.
I then created a new Game Service Entity, and when I got to the SHA signing bit, I entered my SHA1 certificate fingerprint.
You DON’T need to publish the Game Service Entity, before you can test it. As long as your user signed in to the Phone is listed in the TESTING ACCESS area.
Hey, @benny5, about the client ID, I have one of my apps with XXXXXXXXXXX.apps.googleusercontent.com, and it has no issue signing in. So the first client ID would not be always be incorrect. I think there was something else that caused the client ID not to work right the first time you created one, but the second one was generated correctly.
When I linked my first app, it had issue with client ID and I had to go through cleaning process, and for that app, the client ID looks like XXXXXXXXXXX-YYYYYYYYYYYYYYYYYYYYYYYYYYYY.apps.googleusercontent.com, but for my second app (which is a separate product and has its own GPGS set up), the client ID looks like XXXXXXXXXXX.apps.googleusercontent.com, and that’s the first client ID I created for this app.
Naomi
Hey Naomi,
That’s interesting. I made a second game and managed to login with the simpler type of client ID as well. I have no idea what’s going on. But both seem to work under certain conditions.
HI andershjarnaa ,
still i’m facing the same problem sign in error. I make three time keystore and SHA1 but SHA1 not match with package name. when i create SHA1 with this statement it generate error like this
keytool -exportcert -alias mytestapp -keystore mytestapp.keystore -list -v
$$$$$$$$$$$$$$$$$$$$ keytool -exportcert -alias mytestapp -keystore ~/.mytestapp.keystore -list -v
Enter keystore password:
keytool error: java.lang.Exception: Alias <mytestapp> does not exist
java.lang.Exception: Alias <mytestapp> does not exist
at sun.security.tools.KeyTool.doPrintEntry(KeyTool.java:1339)

at sun.security.tools.KeyTool.run(KeyTool.java:172)
at sun.security.tools.KeyTool.main(KeyTool.java:166)
can u help me about this problem…m really thankful to you
Hi corona208, I’m, not an expert in Java and the keytool at all, but it seems like there is a problem with the command you have entered. Are you sure that your certificate is called mytestapp?
Else I would suggest that you try and issue a new certificate from the beginning, and follow the process very carefully.
Have a look at this article to generate the keystore certificate.
http://developer.android.com/tools/publishing/app-signing.html
@corona208, you might want to replace the alias mytestapp with mytestappalias.
Edit: Actually, try this.
Launch Corona SDK > File > Build and select Android for your app.
It should bring up the popup screen that shows your application name, version code, etc. along with your Keystore and Key Alias.
It should show mytestapp.keystore as the Keystore and something else for Key Alias.
So, let’s say, your keystore is mytestapp.keystore and Key Alias is mytestappalias, then you change your command line like so:
Wrong one:
keytool -exportcert -alias mytestapp -keystore ~/.mytestapp.keystore -list -v
Right one:
keytool -exportcert -alias mytestappalias -keystore ~/.mytestapp.keystore -list -v
Naomi
Hi andershjarnaa and Naomi,
I also try the same method as u telling keystore are generate successfully without problem with this command
I’m on Mac
keytool -genkey -v -keystore testapp.keystore -alias testapp -keyalg RSA -validity 999999
answered all question and then generate keystore but when i am create SHA1 with this command
keytool -exportcert -alias mytestappalias -keystore ~/.mytestapp.keystore -list -v
it gives error like this “Keystore file does not exist” m also give path within this command like as
keytool -exportcert -alias mytestappalias -keystore ~/.android/debug.keystore -list -v but it gives error
when I generate SHA1 with correct method then i solved all error. due to this error Google Play Game Service gives Sign-in error.
please help me how i remove this error. or tell me how i give the path init.
I read the whole article of GPGS service and implement accordingly to the document but still face the problem X_X :@
M right or not???

can anyone email me source code of working google play game service in which show leader board and achievements show. m really thankful to you.
