Answer 1

change your manifest like this

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.LoginApp">
        <activity
            android:name=".second"
            android:exported="true"></activity>
        <activity
            android:name="com.your.package.Splash" //put yout class here
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        </activity>
    </application>

</manifest>

First time your android will run activity with category LAUNCHER, so change your activity class in category.LAUNCHER with your class (Splash.java)
