I have got a google token and with it, I request an authentication URL from google with the following cURL command:
curl --data 'accountType=&Email=&has_permission=1&Token= + $$TOKEN$$ + &service=weblogin%3Acontinue%3Dhttps%253A//www.google.com/dashboard/&source=&androidId=&app=&client_sig=&device_country=&operatorCountry=&lang=&RefreshServices=' -k 'https://android.clients.google.com/auth'
How can I convert this command into a pure java command with URL connections or the Apache HTTP library? So that I don't have to use the cURL binary any more.
I saw several examples but I'm facing some troubles with the POST parameters. I can't get is right.
My java try:
$$ TOKEN $$ --> must be replaced by the real token.

I just had to add the SSL cert validation and then it worked.
If you use java.net.HttpURLConnection you can write the bytes of the post data right to the outputstream. So all you would have to do is take your --data and convert it to bytes and write it to the stream.
