无法将 RxJava 与 Hengam SDK 一起使用
Can't use RxJava with Hengam SDK
我最近在我的项目中添加了 Hengam SDK；但不幸的是我不能再使用 RxJava 并且它会导致重复异常。值得一提的是，在将 SDK 添加到项目之前，一切正常。

这是怎么回事？是否与SDK有冲突或需要额外配置才能使用RxJava？
如有任何回应，我们将不胜感激...
您需要从依赖项中排除 RxJava 组或从 gradle 中移除 RxJava 依赖项。
implementation ('io.hengam.lib:base:1.0.5') {
exclude group: 'io.reactivex.rxjava2', module: 'rxjava'
}
AFAIK，Hengam 有一个自定义的 RxJava2（为了保持 SDK 的最终大小）。因此，如果您想将 RxJava2 与 Hengam 一起使用，则需要排除它的自定义 RxJava2 并实现实际的库。
implementation ('io.hengam.lib:base:1.0.8') {
exclude group: 'io.hengam.lib', module: 'rxjava'
}
implementation 'io.reactivex.rxjava2:rxjava:2.2.9'
因此 io.hengam.lib:rxjava 不会导入到 class 路径，而是添加 ReactiveX 的 RxJava2。
注:
1. 使用RxJava2 2.2.9 或更高版本。
2. RxJava3 与 RxJava2 相比有不同的封装。所以确保你添加 RxJava2
我最近在我的项目中添加了 Hengam SDK；但不幸的是我不能再使用 RxJava 并且它会导致重复异常。值得一提的是，在将 SDK 添加到项目之前，一切正常。
