【中文标题】我的应用程序正在模拟器上运行并完全运行，但在物理设备上崩溃【英文标题】：My application is running and working fully on the Emulator, but crashing on a physical device 【发布时间】：2019-10-07 09:03:18 【问题描述】：你们能帮我解决我的问题吗？我的程序在 android Studio Emulator（Pixel 2 API 28）上运行没有问题，但是在我将它安装到我的手机（Samsung Galaxy S8+ API 28）上之后，每次我点击播放按钮时它都会继续崩溃:(。我在一些手机上也试过了，我仍然有同样的问题
实际上这不是我的程序，但我在 youtube 上找到了它，但是在 youtube 中制作代码的人给了我在我的学期项目中使用它的绿灯。
关于如何在 youtube 中制作该程序的视频链接：

这是你可以运行的源代码链接：

我只想在物理设备上运行此代码，尤其是在我的手机三星 Galaxy S8+ 上。我似乎无法解决我有点绝望的问题。我对 Java 编程很陌生，非常抱歉。

【问题讨论】：
发布您尝试过的代码。 用 logcat 发布一些代码 你试过这个解决方案吗？ ***.com/questions/17605662/… 如果是，请发布您的代码。 public void dispatchMessage(@NonNull Message msg) if (msg.callback != null) handleCallback(msg); else if (mCallback != null) if (mCallback.handleMessage(msg)) return; 处理消息（味精）；这是 Handler.java 中代码的一部分 这段代码中有很多“（@NonNull Message msg）”消息，它们都说“'android.annotation.NonNull'在'android.annotation'中是不公开的。注释'。无法从外部包访问“ 它与位图或ImageView有关，您尝试过这种解决方案吗？ ***.com/questions/17605662/… 【参考方案1】：实际问题出在 GameView.java:64 中，其中使用了固定的屏幕高度和宽度，而不是动态的。此代码在屏幕低于或等于 1920x1080 像素的设备上运行流畅。
当屏幕尺寸超过 screenRatioX 和 screenRatioY 时会导致问题 Flight.java:32 中变为 o strong> 通过强制转换，导致异常为
宽度和高度必须 > 0
要使用动态屏幕尺寸，您可以使用：
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
分别使用 size.x 和 size.y 而不是 1920f 和 1080f。谢谢
【讨论】：
我有点明白这确实是 Asaduzzaman 先生的问题，我应该在哪里找到替换它的类/代码？我把 GameView.java 供你参考兄弟。我只是一个java初学者真的很抱歉 显示显示 = getWindowManager().getDefaultDisplay();点大小 = new Point(); display.getSize(大小); this.screenX = screenX; this.screenY = screenY; screenRatioX = size.x / screenX; screenRatioY = size.y / screenY;我尝试将它放在 GameView.java 上，但它显示“无法解析方法 'getWindowManager()'。它是红色字体 使用activity.getWindowManager().getDefaultDisplay(); :) 先生。 Asaduzzaman 我真的不知道该怎样感谢你。如果没有你，我不知道我会怎么做。非常感谢上帝保佑你！你真的帮了我很多:) 欣赏它。 欢迎@KennethQuilantang，祝你好运。以上是关于我的应用程序正在模拟器上运行并完全运行，但在物理设备上崩溃的主要内容，如果未能解决你的问题，请参考以下文章
