Android studio generating two apps the same way

Question

I developed an apk, but from the end of the project here he was always emulating two identical applications on my phone, same functions, icons. The difference between one and the other is that one has the splash and the other does not. Then when I managed the APK, I installed it on mobile and appeared the two apps. In the uninstallation I by selecting an apk to uninstall the other one is also uninstalled. Someone has been through this?

</application>

Answer 1

Change your Manifest

<activity
        android:name=".Splash"
        android:label="Splash">
        <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="WF Projetos">
    </activity>

The project can only have one action.MAIN and category.LAUNCHER.
