Problem with accessing internet from Ruboto

[toomus]

Hi,

I have problem with connecting to internet from Ruboto with this code:

Thread.start do
  url = URI.parse('https://my.domain.com')
  http = Net::HTTP.new(url.host, url.port)
  http.use_ssl = true
  data = 'some_param=test'
  headers = {
      'Cache-Control' => 'no-cache',
      'Content-Type' => 'application/x-www-form-urlencoded'
  }
  resp = http.post('/api/v2/token', data, headers)
  JSON.parse(resp.body)['access_token']
end

Application is running and in adb logcat there is no error, only a lot of Garbage Collector logs:

Hi!

It may be that your exception is swallowed by the Thread. Try encapsulating the whole Thread block within begin … rescue <log the exception> end.

Hi donV,

Thanks for suggestion. I add rescue and nothing was raised, but I also add some logs to code and looks like it hangs in this line:

resp = http.post('/api/v2/token', data, headers)

And in adb logcat is message:

I/System.out( 2547): Starting JOpenSSL Service
I/art     ( 2547): WaitForGcToComplete blocked for 9.569ms for cause HeapTrim

OpenSSL and https has been a problem. Can you try it with “http” and see if it works then? If so, we know it is an SSL problem.

Yes, it looks like issue with SSL - http works. Is there any possible solution for this?

[Uwe Kubosch]

Yes, but it will probably involve getting JRuby 9K to work.
