Alternative solution is to set activity's orientation using ActivityLifecycleCallbacks.

import android.app.Activity
import android.app.Application
import android.content.pm.ActivityInfo
import android.os.Bundle

class App : Application() {

    override fun onCreate() {
        super.onCreate()
        registerActivityLifecycleCallbacks(object : ActivityLifecycleCallbacks {

            override fun onActivityCreated(activity: Activity, savedInstanceState: Bundle?) {
                activity.requestedOrientation = ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT
            }

            override fun onActivityStarted(activity: Activity) {}
            override fun onActivityResumed(activity: Activity) {}
            override fun onActivityPaused(activity: Activity) {}
            override fun onActivityStopped(activity: Activity) {}
            override fun onActivitySaveInstanceState(activity: Activity, savedInstanceState: Bundle) {}
            override fun onActivityDestroyed(activity: Activity) {}
        })
    }

}

The accepted answer is correct. However, if you happen to be doing cross-platform development in C# using Uno Platform the Activity configuration is defined in an Activity attribute in the class. I'd expect this is the same if you're doing Xamarin or Xamarin Forms development.

Set: ScreenOrientation = ScreenOrientation.Portrait in the attribute parameters.

Here's an example within my MainActivity.cs class-level attribute:

[Activity(MainLauncher = true,
        ConfigurationChanges = global::Uno.UI.ActivityHelper.AllConfigChanges,
        WindowSoftInputMode = SoftInput.AdjustPan | SoftInput.StateHidden,
        ScreenOrientation = ScreenOrientation.Portrait)]
public class MainActivity : Windows.UI.Xaml.ApplicationActivity { }

#unoplatform #xamarin #csharp #windows #crossplatform

in new SDk of android (24 and above) you can use in Manifest.xml in activity tag as you want:

<activity
            android:name=".feature.main.MainActivity"
            ********* android:screenOrientation="locked" ******
            android:configChanges="uiMode"
            android:windowSoftInputMode="adjustPan"
            android:exported="true">

and it work!

Try this: (if SDK 23 & above)

Add your AndroidManifest.xlm;

    <activity android:name=".YourActivity"
        android:screenOrientation="locked"/>

like this.

in the manifest:

<activity android:name=".activity.MainActivity"
        android:screenOrientation="portrait"
        tools:ignore="LockedOrientationActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

or : in the MainActivity

@SuppressLint("SourceLockedOrientationActivity")
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

There are two ways,

  1. Add android:screenOrientation="portrait" for each Activity in Manifest File
  2. Add this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); in each java file.

Old post I know. In order to run your app always in portrait mode even when orientation may be or is swapped etc (for example on tablets) I designed this function that is used to set the device in the right orientation without the need to know how the portrait and landscape features are organised on the device.

   private void initActivityScreenOrientPortrait()
    {
        // Avoid screen rotations (use the manifests android:screenOrientation setting)
        // Set this to nosensor or potrait

        // Set window fullscreen
        this.activity.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

        DisplayMetrics metrics = new DisplayMetrics();
        this.activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);

         // Test if it is VISUAL in portrait mode by simply checking it's size
        boolean bIsVisualPortrait = ( metrics.heightPixels >= metrics.widthPixels ); 

        if( !bIsVisualPortrait )
        { 
            // Swap the orientation to match the VISUAL portrait mode
            if( this.activity.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT )
             { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); }
            else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT ); }
        }
        else { this.activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR); }

    }

Works like a charm!

NOTICE: Change this.activity by your activity or add it to the main activity and remove this.activity ;-)

I use

 android:screenOrientation="nosensor"

It is helpful if you do not want to support up side down portrait mode.

In the manifest, set this for all your activities:

<activity android:name=".YourActivity"
    android:configChanges="orientation"
    android:screenOrientation="portrait"/>

Let me explain:

  • With android:configChanges="orientation" you tell Android that you will be responsible of the changes of orientation.
  • android:screenOrientation="portrait" you set the default orientation mode.
