Changing the screen orientation in the Android Manifest does not have any effects-CodePudding

I would like to have my app only in landscape mode. For that I use the suggested code in the Android manifest that is recommended here Force "portrait" orientation mode

However, on the Android emulator the layout is always in portrait mode. Even if I rotate the Emulator, the layout orientation does not change. Any idea why this problem occurs?

Here you can see the Android manifest:

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

    <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.CanvasDrawingSample">
        <activity android:name=".MainActivity">
            android:screenOrientation="landscape"
            android:configChanges="orientation|keyboardHidden">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />


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

</manifest>

and here is the main file:

package com.nikhiljain.canvasdrawingsample

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
    }
}

CodePudding user response：

you are closing <activity tag too soon, rest of attributes (besides name) are outside declaration and "doesn't count"

    <activity android:name=".MainActivity">      <----- !!!!
        android:screenOrientation="landscape"
        android:configChanges="orientation|keyboardHidden">

should be

    <activity android:name=".MainActivity"
        android:screenOrientation="landscape"
        android:configChanges="orientation|keyboardHidden">
