and this is taking much time as far as i think so :( ...... I'm just curious that how to load app like facebook that as we tap on fb icon and the app loads blazing fast and splash screen is shown but in my app i'm having this problem. Any help will be appreciated :) ..

My androidmanifest here

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/Theme.AppCompat.Light.NoActionBar">
        <activity android:name=".splashscreen"
            android:label="@string/app_name">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".MainActivity">
        </activity>
        <activity
            android:name=".ShowPosts"
            android:label="@string/posttitle"
            android:parentActivityName=".MainActivity"/>
        <activity android:name=".LiveScores" />
    </application>

you can read more here: Add splash in application

if you want also to create an animation between the screens, see transitions between activities:
