Why the App is installed twice?

When I run the Android App Studio, the cell is the App is "installed" twice: There are two apps one called "SplashScreenActivity" and other "Doctor Quiz" (my app), the two are equal. If I uninstall one, the other also uninstalls.
Why does this happen? How do I "install" just my app? (DoctorQuiz)

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.morais.daniela.doctorquiz" >
    <uses-permission android:name="android.permission.INTERNET"/>
    <provider android:authorities="com.facebook.app.FacebookContentProviderXXXX"
        android:name="com.facebook.FacebookContentProvider"
        android:exported="true" />
    <application
        android:allowBackup="true"
        android:icon="@drawable/medicine_box_icon2"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <meta-data android:name="com.facebook.sdk.ApplicationId" android:value="@string/facebook_app_id"/>
        <activity
            android:name=".Activity.SplashScreenActivity"
            android:configChanges="orientation|keyboardHidden|screenSize"
            android:label="@string/title_activity_splash_screen"
            android:theme="@style/FullscreenTheme">
        <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
        </activity>
        <activity
            android:name=".Activity.QuestionsActivity"
            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=".Activity.ResultActivity"
            android:label="@string/title_activity_result" >
            <activity android:name="com.facebook.FacebookActivity"
                android:configChanges=
                    "keyboard|keyboardHidden|screenLayout|screenSize|orientation"
                android:theme="@android:style/Theme.Translucent.NoTitleBar"
                android:label="@string/app_name" />
        </activity>

    </application>

</manifest>

Most probably you have specified two activities as launcher in manifest file. This invokes this issue.

Launcher specification appearing twice here

change it to

Corrected specification

The app is not installed twice. You are not looking at apps. You are looking at launchable activities, ones with this <intent-filter>:

        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

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

You have two activities with that <intent-filter>, and so you will have two activities in the home screen launcher. If you do not want both of those activities in the home screen launcher, remove that <intent-filter> from one of them.
