Question

我无法复制它但是我看到这个视图注入崩溃通过Crashlytics影响了大约5-10％的用户。

该应用程序在我投入的所有内容上都能正常运行，但有些用户肯定没有这种体验。

我错过了什么？为什么会在某些设备上发生这种情况，而不是在同一型号的其他设备上发生？

受影响的设备包括Nexus 4和Nexus 5.我在两者上都尝试过（Nexus 4是我的主要设备）没有任何问题。受影响的还有几个三星。

有什么想法吗？

这是完整的堆栈跟踪，然后是愚蠢的简单类和布局xml：

Answer 1

即使AndroidManifest禁止活动，也有办法强制活动进入纵向模式。我在您的应用中尝试了https://play.google.com/store/apps/details?id=com.googlecode.eyesfree.setorientation，并且您提到了例外情况。

因此，我建议您查看布局，可能是您忘记了以纵向模式加载并且不包含buttonScores的activity_welcome.xml。

ButterKnife在某些设备上注入问题

- WelcomeActivity.java

- activity_welcome.xml
