ClassNotFoundException动态模块初始值设定项Android

因为我更新了我的android studio和sdk。这些错误立即开始发生，阻止了我向数据库中的一个孩子写信，我不知道问题出在哪里。但是，当我试图从正在发生的“EditCarPostActivity”活动写入数据库时，从其他活动中，我似乎可以完美地写入、更新和检索信息。请帮我解决这个问题。我将在下面发布一些活动

对于（int i=0；i我在我的华为设备（android 7.0的P9 Lite）上也遇到了同样的问题，要解决这个问题，只需删除当前安装的Google Play Services版本，将其恢复为我们设备附带的默认版本（这可以通过设置应用程序完成）。
然后重新启动您的设备，并将Google Play Services应用程序更新至最新版本。然后运行您的应用程序，它应该可以正常工作。
我在我的华为设备（android 7.0的P9 Lite）上遇到了同样的问题，我通过在设置-->应用程序-->谷歌播放服务-->存储中清除缓存解决了这个问题

我希望这对你有帮助。
干杯！
我的荣誉STF-L09也遇到了同样的问题。我通过将google play服务更新为测试版解决了这个问题，因为华为和荣誉设备上的当前版本存在已知问题
