Android Question Google error "unusual traffic from your computer network"

[prokli]

I am using this small piece of code to access Googles translation engine:

        job.Initialize("", Me)
        poststr = GOOGLE_LNG & procs.SRCLANG & "&tl=" & procs.DSTLANG & "&dt=t&q=" & spoken
        job.PostString(poststr, "")
        job.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.3; rv:36.0) Gecko/20100101 Firefox/36.0")   
        Wait For (job) JobDone(j As HttpJob)
        If j.Success Then
            'translation successful
            trans = job.GetString
            'get translation out of JSON formatted string
            trans = procs.ParseJson(trans)
        End If

This code works pretty fine for me but from time to time this code stops working. In the debug window I can see that Google starts blocking my IP address telling me that " systems have detected unusual traffic from your computer network". I know that polling to fast results in blocking by Google. So, I have included a timer (20 sec) to my code to avoid fast polling. Nevertheless, after days and sometimes after hours Goggle is blocking me again. Is there any way how I can refuse this behaviour by code or configuration. After resetting my router everything works fine again.

It appears your app is using a google translation service that is meant for occasional "human" user requests, and not requests from automated systems (your app).

Result: cake....
Copy and paste to Chrome or any other browser and see what happens!

Are you using this code in an app in the playstore?

How often is this code being run? (for example, 2 times a day or 100 times a day or ?)

It would be strange for google to block your ip if you only occasionally use that code.

I think there is no programmatically way to bypass this issue. Unfortunately! Learning vocabulary requires permanently access to Google (may be 10 – 20 times per minute). If IP has been blocked, I restart my router and everything is fine again. But this is – of course – not a problem solver when sitting in a restaurant or café.
