Android Question How to cancel active Http requests

[Semen Matusovskiy]

Hi, guys --

In some moment one activity starts another and dies.
But there is a problem with current downloads, which do not allow to die immediatelly.

I saw very old post with following sample

   Dim reflectorInstance                                                        As Reflector

   reflectorInstance.Target = HttpUtils2Service.hc
   reflectorInstance.Target = reflectorInstance.GetField ("client")
   reflectorInstance.Target = reflectorInstance.RunMethod ("getConnectionManager")
   reflectorInstance.RunMethod ("shutdown")

where hc is HttpClient inside HttpUtils module.
Probably this works with OkHttpClient also.

But I am a little confused that httpClient.getConnectionManager() is deprecated.

What is correct method (I need a solution for API14+)

The correct solution is to make the requests from a service. You can use the starter service for this. This way the responses will not start the activity if you don't want to.

Hi, Erel --
Thanx for reply.
If you offer to transfer download from activity to service, it's not a good solution for me. First of all, because I have a lot "Wait For".

I made a small sample (attached). Run it and click "Start B" asap. Then wait.
"Wait for" after 10 seconds (timeout) activates main activity.
Meanwhile I want simply to forget about download and to kill main activity.

I attempted to change Http2Service (modified.zip). Changes are marked by *** My ***. To ignore previous http requests it's necessary to add statement

    HttpUtils2Service.taskCounterMin = HttpUtils2Service.taskCounter

inside the activity.
It looks that works, but I am not sure that I released all resources. Can you look ?

Looks fine. You can add If File.Exists before you try to delete.
