Integrating Google+ oAuth into your android app

Learn how to implement Google+ signup in your android app. We all know most of the app support signup with your social account like facebook or twitter etc. Now before you start integrating Google+ features in your application you need to follow some step and get some required key to access google+ information of users.

Step 1: Login to google developers console and create new project inside it now after adding required info you need to enable google+ api under its section enable it.

Step 2. Now create new project in android studio. Open your project gradle we need to add dependencies in your build.gradle.

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.google.android.gms:play-services:7.5.0'
}

dependencies {

compile fileTree(dir: 'libs', include: ['*.jar'])

compile 'com.android.support:appcompat-v7:22.2.0'

compile 'com.google.android.gms:play-services:7.5.0'

}

Step 3. Open project Manifest file add permissions in it.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.googlepluszetaintegration">

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


    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">

        <meta-data
            android:name="com.google.android.gms.version"
            android:value="@integer/google_play_services_version" />
        <activity
            android:name=".MainActivity"
            android:label="Trinity Google+">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

<?xml version="1.0" encoding="utf-8"?>

<manifest xmlns:android="http://schemas.android.com/apk/res/android"

package="com.googlepluszetaintegration">

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

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

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

<application

android:allowBackup="true"

android:icon="@mipmap/ic_launcher"

android:label="@string/app_name"

android:theme="@style/AppTheme">

<meta-data

android:name="com.google.android.gms.version"

<activity

android:name=".MainActivity"

android:label="Trinity Google+">

<intent-filter>

</intent-filter>

</activity>

</application>

</manifest>

Step 4. Now open your Layout file where we add some button and textview to login and show logged user data.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"

        android:visibility="gone">

        <ImageView

            android:layout_weight="1"/>

        <LinearLayout

                android:padding="5dp"
                android:textSize="20dp" />


            <TextView

        </LinearLayout>
    </LinearLayout>

    <com.google.android.gms.common.SignInButton
        android:id="@+id/btn_sign_in"
        android:layout_width="fill_parent"

        android:visibility="gone" />

</LinearLayout>

android:layout_width="match_parent"

android:layout_height="match_parent"

android:orientation="vertical"

Step 5. Now add following given below code in your activity to complete your login.
