    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:support-v4:22.2.0'
    compile 'com.google.android.gms:play-services-base:8.4.0'

    compile 'com.google.android.gms:play-services-auth:8.4.0'
    compile 'com.facebook.android:facebook-android-sdk:4.7.0'
    compile project(':androidHorizontalListView')
    compile('com.twitter.sdk.android:twitter:1.11.0@aar') {
        transitive = true;
    }
    compile 'com.google.android.gms:play-services-appindexing:8.4.0'
}
apply plugin: 'com.google.gms.google-services'

Project Gradle:

buildscript {
    repositories {
        jcenter()
    }

        classpath 'com.google.gms:google-services:2.0.0-alpha3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Is there anything that i have missed to implement please let me know if there

Answer 1

Remove:

mGoogleApiClient = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();

from onCreate() last line number, it overwrite object.

Answer 2

you can use like this:

Intent shareIntent = new PlusShare.Builder(this)
.setType("text/plain")
.setText("Android Tutorial #android #tutorial")
.setContentUrl(Uri.parse("http://androidtutorialforbeginners.com"))
.getIntent();
