Android 7上的Retrofit 2 + RxJava StackOverflowError

时间：2017-08-22 07:03:42

标签： android rx-java retrofit2 android-7.0-nougat android-7.1-nougat

我看到Crashlytics中仅有一些与Retrofit 2和RxJava相关的Android 7中的错误。根本没有提及任何应用程序代码。设备尚未植根，应用程序主要不在焦点。到目前为止，我的任何设备都没有被复制。

Stacktrace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？

1 个答案:

答案 0 :(得分：1)

基于堆栈跟踪，您似乎拥有非常嵌套的merge运算符。是否有任何地方可以使用Observable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());

或等效的东西（可能通过.scan()）？
