Android Studio中的IllegalStateException：只有全屏活动才能请求方向[重复]

Question

我的应用程序中有一个教程活动，其中包含一堆幻灯片，其中包含有关如何使用该应用程序的一些详细信息。我希望我的整个应用程序仅处于 PORTRAIT 模式，因此我使用以下代码创建了一个自定义 Application 类：

public class DokkanCardsApplication extends Application {
@Override
public void onCreate() {
    super.onCreate();
    registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
        @Override
        public void onActivityCreated(Activity activity, Bundle bundle) {
            activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }

        @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 bundle) {

        }

        @Override
        public void onActivityDestroyed(Activity activity) {

        }
    });
}

}

现在，问题是本教程在我第一次安装它时运行良好，但现在它只是崩溃并抛出 IllegalArgumentException 异常说 只有全屏活动可以请求方向强>。经过一番研究，我意识到这是谷歌的错误（如果我错了，请纠正我）但我还没有找到解决方法。异常指向我的自定义 Application 类和我的教程类您可以在下面看到。但是，我还没有发现问题。有什么想法吗？

教程.java：

public class Tutorial extends MaterialIntroActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    addSlide(new SlideFragmentBuilder()
            .title("Main Screen")
            .description("Search through the entire Dokkan Cards database and find any card you like.")
            .image(R.drawable.image_main)
            .backgroundColor(R.color.mainScreen)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());


    addSlide(new SlideFragmentBuilder()
            .title("Tap & Long-Press Actions")
            .description("Tap on any card icon to view it's details or Long-press on it to add it to either one of your boxes")
            .image(R.drawable.image_long_tap)
            .backgroundColor(R.color.long_tap)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Side Menu")
            .description("Swipe from left to right to access a handful of menu options")
            .image(R.drawable.image_menu_slide)
            .backgroundColor(R.color.side_menu)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Auto-Save")
            .description("This app saves your box data automatically when you close the app so that you don't have to worry about saving manually")
            .image(R.drawable.image_auto_save)
            .backgroundColor(R.color.auto_save)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Data Security")
            .description("Your data is 100% safe since it cannot be accessed by anyone else.All data are stored locally on your device and not on a server or cloud")
            .image(R.drawable.image_data_security)
            .backgroundColor(R.color.data_security)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());

    addSlide(new SlideFragmentBuilder()
            .title("Donations")
            .description("Although donations are not mandatory, they help a lot in the app's development process. You can submit your donation via the website tab in the app's side menu.")
            .image(R.drawable.image_donation)
            .backgroundColor(R.color.donations)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());

   addSlide(new TutorialDisclaimerSlide());

    addSlide(new SlideFragmentBuilder()
            .title("That's it")
            .description("That's the end of this tutorial.You can access it at any time from the top right corner of the app")
            .image(R.drawable.image_tutorial)
            .backgroundColor(R.color.tutorial_end)
            .buttonsColor(R.color.colorPrimaryGLB)
            .build());
}

}

*如果有人感兴趣，这里是我在 Manifest.xml 文件中使用自定义应用程序类的部分：

<application
    android:name=".presenter.DokkanCardsApplication"
    android:allowBackup="true"
    android:fullBackupContent="@xml/backup_descriptor"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

感谢@Khemraj 的link，我设法通过使用以下 if 语句包围 custom Application 类的 onActivityCreated 方法的内容来解决问题：

if(android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.O) {
    activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
