I downloaded and imported the gplus-quickstart demo project from https://github.com/googleplus/gplus-quickstart-android
and I am unable to login with my g+ account, I keep getting the error "Google Play services error could not be resolved: 17"
I made no changes to the project itself other than adding two permissions
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
I figured these permissions may be needed and were just forgotten. The other steps I took were the following,
1) I got the SHA fingerprint from console
keytool -list -v -keystore "%USERPROFILE%\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
2) I then enabled google+ API from the developers console and API section 3) I then created a new client ID from the credentials section on the developers console. I filled out the information, making sure to select "Installed application" as the application type and inputting the same package name as the demo package name, as well as the SHA I got from console.
After these steps, I ran the application and when trying to login I receive in my logs the following:
Google Play services error could not be resolved: 17
What am I doing incorrectly? Is there something in the gradle files I should fix? Do I need to make some further updates and changes? I will post my class below, maybe I have old version or something.

I am definitely sure that this error will be caused by not entering your(or entering incorrect) package name in the Google API console.
Just go through all the steps sincerely once again as noted here :
If you have created a new project, then also you must register a new Application(with package name and SHA1) in "Credentials" section of the Google Console API.
Hope it helps you :-)
