Google+ login Integration crashes android application

Question

I am integrating Google+ Login integration in my android application. I am following this tutorial. http://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/ I followed each and every step, but when I run application on my android device, the application crashes after splash screen.

Log cat shows no error in application, but shows error in google play service library. Here is the Log cat

Permissions in Manifest file

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />

<meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

If I remove this code and run the application. Then Application runs fine, but after adding this code, the app crashed after splash screen.

Any help will greatly appreciated... Thanks in advance

Answer 1

[[Resolved]] The error is resolved by just removing 'null' as a parameter from addApi(Plus.API) method

mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this).addApi(Plus.API)
.addScope(Plus.SCOPE_PLUS_LOGIN).build();

PS Just keep in mind that you have to generate the client ID for that email address which you are using in your android device as primary email address. This also help me in my case.
