Android studio installing APK on phone but can't find the app

Question

I am new to Android Studio and I am trying to deploy an APK to my mobile device in order to test the app. I build the APK successfully but when I install the apk of the app in my device I couldn't see it or cannot be open. But I can see the apps in the app manager showing that I installed it.

here is the code in my manifest file.

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="Pasig NutriCare"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.DEFAULT" />

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

Looking for help. Thanks in advance.

Make sure you specify the launcher activity for the app in your AndroidManifest.xml file:

<activity android:name=".YOURACTIVITY" android:label="@string/app_name">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>
