Android Studio 中的 IllegalStateException：只有全屏活动可以请求方向
IllegalStateException in Android Studio: Only Fullscreen activities can request orientation
我的应用程序中有一个教程 activity，其中包含大量幻灯片，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，所以我使用以下代码创建了一个自定义 Application class ：
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) {
}
});
}
}
现在的问题是，每当我第一次安装教程时，它都可以正常工作，但现在它崩溃并抛出 IllegalArgumentException 异常，提示 仅全屏活动可以要求方向。经过一番研究，我意识到这是 Google 的错误（如果我错了请纠正我）但我还没有找到解决方法 it.The 异常指向我的自定义 Application class 和我的教程 class 你可以看到 below.However，我还没有找到 issue.Any 的想法？
Tutorial.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")

.image(R.drawable.image_long_tap)

.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());
}
