我最近将我的应用程序发布到了android Play商店。
我特别从一台设备上看到了很多错误日志。这是Sony Experia S.
我联系了该设备的所有者，他说他有最新版本的android（不知道具体版本）。
我从一位colluege开发者那里听说，有更多已知的sies设备和android。
这个应用程序特别适用于碎片......不知道这是不是问题但是...也许索尼不知道如何应对它们。
有没有人知道这个问题可能是什么。
错误日志如下所示：

日Thnx
答案 0 :(得分：0)
只需对代码进行空检查：
KVOHome Acvitivity，第52行。 在com.crosscommunications.kvodeventer.KVOHome.onCreateView（KVOHome.java:52）
最有可能的是，索尼会向您的代码发送一个空值。
