android - 改造:偶尔获取 java.util.NoSuchElementException

Question

我正在使用 retrofit-beta2，我时常遇到以下崩溃。我不确定我做错了什么。如果有人能给我一个解决问题的提示，那就太好了。

Answer 1

如 this 中所述问题有两种可能:

OkHttp has a bug where we’re attempting to recover when we shouldn't be because we’ve exhausted all of the available routes.

OkHttp has a bug where you’ve got a custom DNS implementation that returned zero IP addresses for a host and we didn't reject that.

我的建议是使用新版本的 retrofit 和 okhttp，因为 Retrofit 2 已经发布了。

compile 'com.squareup.okhttp3:okhttp:3.1.2'
compile 'com.squareup.retrofit2:retrofit:2.0.0'
