<activity android:screenOrientation="landscape"
      android:name=".BasicLayoutCheckActivity"

Answer 1

In the Manifest, you can set the screenOrientation to landscape for all the activities . You have placed for one activity so other activities are opening in portrait, So for fixing set all your activities with orientation as your first activity. It would look something like this in the XML:

<activity android:name=".BasicLayoutCheckActivity" android:screenOrientation="landscape"></activity>

Answer 2

To avoid having to do this for every activity you can register an activity lifecycle callback in your custom application class (if you have one).

Something like...

public class MyApplication extends Application {

   @Override
    public void onCreate() {
        super.onCreate();

        //Lock orientation in landscape for all activities, yaay!
        registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
            @Override
            public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
                 activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);                  
            }

            @Override
            public void onActivityStarted(Activity activity) {

            }

            @Override
            public void onActivityResumed(Activity activity) {

            }

            @Override
            public void onActivityPaused(Activity activity) {

            }

            @Override
            public void onActivityStopped(Activity activity) {

            }

            @Override
            public void onActivitySaveInstanceState(Activity activity, Bundle outState) {

            }

            @Override
            public void onActivityDestroyed(Activity activity) {

            }
        });
    }
}

You can also use the following in the onCreate() method:

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);

Hey check this out In the androidmanifest file inside activity add it

<activity
android:screenOrientation="landscape"
android:configChanges="keyboard|keyboardHidden|orientation">

The orientation property has to be set to every individual activity of the application.
