有一个例外,我的应用程序反复出现在Crashlytics(Fabric)上.我使用rxjava2进行改造以进行我的http调用.

这就是崩解剂日志中的所有内容(下图).将不胜感激任何帮助/见解.

解决方法:

如果您没有给订户或Observer抛出lambable .. Rxjava无法捕获这些异常.因此,简单的解决方案是,只要订阅Observable或其他Rxjava类型,就会覆盖onError()方法并根据情况处理它们.

compositedisposable.add(Observable.just("start")        .doOnNext(ignored -> loadingIndicator.onNext(true))        .flatMap(ignored -> repository.getAndroIDDev())        .subscribe(posts::onNext, throwable -> Timber.e(throwable))); //second lambda is the solution, at lease you can log the errors, if you're not willing to handle them
