Why are there two app icons after installing on the android?

Question

My app shows two app icons after installing it on android with React Native. Why is this happening? Any idea?

I am only using one index.js. I do not have an index.android.js and my version of React Native is 0.50.3.

My fault :( I have two activity in AndroidManifest.xml with:

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

Remove one and perfect :)
