问题描述
因此，最近我已将我的react-native应用程序从使用框架的0.59版本更新为使用0.63。一切进展顺利，直到我注意到在将新的.AAB文件上传到Google Play后，我的用户中的一部分（大约10％）开始收到此错误“ dalvik.system.BaseDexClassLoader.findClass”。
经过调查，我发现它仅在某些（不是全部）具有API级别28或29的设备上发生，如下图所示：
这是堆栈跟踪：
java.lang.RuntimeException:

我已经在互联网上搜索了解决方案，并尝试了其中的一些解决方案，但是没有运气来解决它。有人说它与MultiDex支持有关，但是我很久以前就启用了它：
defaultConfig {
multiDexEnabled true
}
还有：
dependencies {
def multidex_version = "2.0.1"
implementation 'androidx.multidex:multidex:2.0.1'
}
如果有人可以对问题的根源有所了解，我将非常感激。这是我的package.json：

谢谢！
解决方法
我有同样的错误，就我而言，这是一个缺少的类。
如果有机会，得到一个有错误的设备，然后在弹出“发送反馈”模式时，单击“预览”按钮，向下滚动，然后选择“堆栈跟踪”。
我可以找出缺少的课程。
,我们设法通过更新zo0r/react-native-push-notification依赖项并使用不建议使用的GCM通知格式进行迁移来解决此错误（Amazon SNS在理论上仍支持该格式，但新版本的zo0r / react-native-push-notification没有） t）转换为FCM格式。
这些更改之后，错误不再出现在Google Play控制台上。
