When I request data from the server, almost cases rxjava can catch timeout exception from okhttp3 at onError() in my rxjava chain, but sometimes the onError() cannot handle the timeout and my app crash with exceptions below:

There are some posts suggest I need to set readTimeout() and writeTimeout() but it doesn't resolve the problem completely. Here my configuration for okhttp3:
@Provides
@Singleton
internal fun provideOkHttpClient(): OkHttpClient {
return OkHttpClient.Builder()
.connectTimeout(15, TimeUnit.SECONDS)
.readTimeout(15, TimeUnit.SECONDS)
.writeTimeout(15, TimeUnit.SECONDS)
.addNetworkInterceptor(StethoInterceptor())
.build()
}
And the retrofit:
@Provides
@Singleton
internal fun provideRetrofit(client: OkHttpClient): Retrofit {
return Retrofit.Builder()
.baseUrl("http://abc.xyz/")
.client(client)
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.addConverterFactory(SimpleXmlConverterFactory.create())
.build()
}
And here are my related libraries:
io.reactivex.rxjava2:rxjava:2.1.8
io.reactivex.rxjava2:rxandroid:2.0.1
com.squareup.okhttp3:okhttp:3.9.1
com.squareup.retrofit2:retrofit:2.3.0
com.squareup.retrofit2:converter-simplexml:2.3.0
