So I put screenOrientation="nosensor" (also tried portrait, as I want every activity only to be able to be vertically) in manifest file, but it only works in MainActivity, but when I change to another activity, it can rotate the page again, why is this happening, and what should I do?

This is my manifest file:

```
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.frisbeecaddy">

    <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/AppTheme">
        <activity android:name=".ActivityNewGame2"></activity>
        <activity android:name=".ActivityResume" />
        <activity android:name=".ActivityNewGame" />
        <activity android:name=".ActivityNewCourse" />
        <activity android:name=".ActivityCourses" />
        <activity android:name=".ActivityPlayers" />
        <activity
            android:name=".MainActivity"
            android:screenOrientation="nosensor">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

```
