Android Question Google Translate API

[tufanv]

Hello

https://cloud.google.com/translate/docs/reference/rest#query_parameters this is the page describing how to use the google api.

I think we must use httputils to send a request but how can we do it ? Lets say
q : hello
source : en
target : es

How can we send this request and to where exactly , I couldnt understand

Thanks

B4J code (I suppose will work on B4X)

'Use Google Free google API translate for translate

'Call Translate Sub to translate a word from sourcelang to destlang (see lang codes at Google)
Translate(wordtotranslate,sourcelangname,destlangname)

'Translate Sub
Sub Translate (jobnamekey As String,sourcelang As String,destlang As String)
    
    Dim job As HttpJob
    job.Initialize(jobnamekey,Me)
    job.Tag = counttrans

    'Use Google Free google API translate
     job.PostString($"https://Translate.googleapis.com/translate_a/single?client=gtx&sl=${sourcelangname}&tl=${destlangname}&dt=t&q=${jobnamekey}"$,"")

    job.GetRequest.SetHeader("Content-Type", "application/json")
    job.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.3; rv:36.0) Gecko/20100101 Firefox/36.0")
    job.GetRequest.SetContentType("application/json")
    job.GetRequest.SetContentEncoding("text/plain")

End Sub

'Gets the Translate query result from Google
Sub JobDone(Job As HttpJob)

  If Job.Success Then
      Dim translatedword as string=Job.GetString

  Else
      LblStatus.Text="Error Translating : Aborting Translate...."

  End If

  Job.release
    
End Sub

Thanks !!

Does anyone have a technique deciphering the result?

translatedword returns differently on every screen rotation. I added
Translate(wordtotranslate,sourcelangname,destlangname) at Created Event in B4A.

Thanks

Thanks for the Google API code.

I created a small test program using this code for B4A:

I have attached the source code export zip.

A few caveats:
I am still using an older version of B4A. There is probably a newer preferred way to use OKHTTP …
My version also does not support Smart Strings – they would be handy.

Hi Barry,
Good to hear from you, I hope all is well with you.
I downloaded your program and ran it WITHOUT changes in the v7.0 B4a and it ran very fast and without a problem
So, it works with the latest compiler very well.
Regards,
Rusty

Hi Barry,
I hope all is well with you. We just had a great trade show and are excited about the future
Did we ever do a BING version of your Goog Trans application?
If so, I don't seem to have a copy of the source. I'm having trouble with the BING Authorization header using bearer and the accesstoken .
Do you know how to do this?
Regards,
Rusty

No, sorry. I've no experience with BING (https://stackoverflow.com/questions...re-microsoft-translator-api-with-php-and-curl)

Hello,
I did use Bing translator a year or two ago.

It was implemented with HTTP, but it was very cumbersome and confusing. There did not seem to be any benefits versus Google.

Bing seemed to morph into Microsoft Cognitive Services. It became confusing, and my implementation stopped working – I stopped using Bing.

My Bing code was based on code snippets from their examples and Google searches.

Thank you very much for posting the code...
Can you explain:

  job.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.3; rv:36.0) Gecko/20100101 Firefox/36.0")

 

[DonManfred]

Can you explain

It is a User-Agent Header. What to explain???

 

[canalrun]

I believe that header tells the receiver (Google Translate) that the request is coming from an NT machine running Firefox.

I believe I read years ago, although I may be wrong, that Google Translate requires a header of this sort in order to function properly.

Wondering how this webservice works , and what is
single?client

If I am going to put the sample code in my app and hundreds of users access this translate service will it still work ?

 

[DonManfred]

single?client

single is the end of the endpoint (url). client the first parameter.

If I am going to put the sample code in my app and hundreds of users access this translate service will it still work ?

If the api does not need a Api key and the free quotea for this endpoint is not reached; why not.
If you use an Api key then it will work with a lot of users for sure.

Note that code above doe not use an Api Key. Check the Google Documentation on how to use an Api Key with this EndPoint.

AFAIK this is an unofficial translation API so it could be dismissed/changed at any time and it could violate copyrights or other rules/laws.
BTW, as of today, it still works ..

They offer a v2 Api for this: https://cloud.google.com/translate/ which is also useable with okhttputils2 (AND using a Key).

For some reasons the translations of large strings as 200 charachters are not returned corectly !!! do not know how to fix or what to do about it .
