Activity 不会随机呈现，三星只显示白屏 [英] Activity won't render randomly, shows only white screen on Samsung
问题描述
所以，我承认这是一个非常模糊的问题.发生的情况是非常随机且很少仅在三星设备(2x S3 和 1xS4 mini)上启动活动(基本上是任何活动，我没有找到共同点)不会呈现并且只显示白屏.有趣的是，实际上视图就在那里，我可以单击白色屏幕，当我点击正确的位置时，我可以使用按钮打开对话框，然后转到下一个活动.更奇怪的是，当下一个活动使用动画打开时，我可以看到活动的几分之一秒.
So, I acknowledge that this is a truly vague question. What happens is that very randomly and rarely on only Samsung devices (2x S3 and 1xS4 mini) the starting activity (basically any activity, I have not found common ground) won't render and shows only a white screen. The funny thing is that actually the views are there, I can click the white screen and when I hit the correct spots, I can open dialogs using buttons, and go to the next activities. What is more weird is the fact that when the next activity opens using an animation, I can see the activity for a fraction of a second.
那么，有没有人见过或经历过这种情况?
So, has anyone ever seen or experienced this?
注意:由于这是一个如此随机的错误，我需要在此处复制整个项目以获得代码示例，但我不能这样做.
Note: As this is such a random bug, I would need to copy the whole project here for code samples and I just cannot do that.

有关可能的解决方法，请参阅 appcompat-v7 v21.0.0 导致在装有 Android v4.2.2 的三星设备上崩溃，其中建议的解决方案是
For a possible workaround, see appcompat-v7 v21.0.0 causing crash on Samsung devices with Android v4.2.2, where the proposed solutions are
使用
-keep class !android.support.v7.internal.view.menu.**,android.support.v7.** {*;}
和
更好的解决方案是添加以下几行:
The better solution is add the following lines instead:
-keep class !android.support.v7.internal.view.menu.MenuBuilder, !android.support.v7.internal.view.menu.SubMenuBuilder, android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

更新:似乎已在 android 7.0 appcompat 库 (SDK 24.0) 中修复
Update: seems like it's fixed in the android 7.0 appcompat library (SDK 24.0)
根据错误报告的最后一篇文章，这应该被修复新版本的支持库(24):https://code.google.com/p/android/问题/细节?id=78377#c374
According to the last posts of the bug-report, this should be fixed on the new version of the support library (24) : https://code.google.com/p/android/issues/detail?id=78377#c374
甚至有人声称它修复了它.
