在 Android 7 上改造 2 + RxJava StackOverflowError
Retrofit 2 + RxJava StackOverflowError on Android 7
我在 Crashlytics 中看到一些与 Retrofit 2 和 RxJava 1 相关的 Android 7 错误。根本没有提及任何应用程序代码。设备尚未植根，应用程序大多未获得关注。到目前为止，在我的任何设备上都没有被复制。
堆栈跟踪如下：

问题不是供应商特定的（三星、摩托罗拉、华为等）。有什么想法吗？
根据堆栈跟踪，您似乎有极其嵌套的 merge 运算符。是否有任何地方可以使用 Observables 集合并执行类似
的操作
Iterator<Observable<T>> it = collection.iterator();
Observable<?> obs = it.next();
while(it.hasNext()) obs=obs.merge(it.next());
或类似的东西（可能通过 .scan()）？
我在 Crashlytics 中看到一些与 Retrofit 2 和 RxJava 1 相关的 Android 7 错误。根本没有提及任何应用程序代码。设备尚未植根，应用程序大多未获得关注。到目前为止，在我的任何设备上都没有被复制。

问题不是供应商特定的（三星、摩托罗拉、华为等）。有什么想法吗？
根据堆栈跟踪，您似乎有极其嵌套的 merge 运算符。是否有任何地方可以使用 Observables 集合并执行类似
Iterator<Observable<T>> it = collection.iterator();
Observable<?> obs = it.next();
while(it.hasNext()) obs=obs.merge(it.next());
或类似的东西（可能通过 .scan()）？
