Ensure your AndroidManifest.xml looks like this:

         ...
        <activity
            android:name=".SplashScreen"
            android:label="..."
            android:screenOrientation="portrait"
            android:theme="@style/Theme.AppCompat.Light.NoActionBar" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
            android:name=".MainActivity"
            android:label="..."
            android:theme="@style/theme">
            <!--android:label="@string/app_name" >-->
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
            </intent-filter>
        </activity>

If you have three times

<category android:name="android.intent.category.LAUNCHER" />

You will have three icons as well. Keep this for your main activity, the one you use to launch your app. Remove it for the others.
