问题
I have tried the following code to implement a translator app using Microsoft Translator API library found here. I have a working internet connection and I have generated the a valid client id and secret but whenever I try to run the code I get the java.net.UnknownHostException.
My code:
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
Translate.setClientId("Screened for the question"); //Change this
Translate.setClientSecret("I have screened the client secret to ask in SO"); //change
final TextView text = (TextView) findViewById(R.id.textView1);
Button Trans1 = (Button)findViewById(R.id.trans);
Trans1.setOnClickListener(new View.OnClickListener(){
public void onClick(View view) {
String word = "Hello";
try {
translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN);
// text.setText(translatedText);
} catch (Exception e) {
e.printStackTrace();
}
}
});
My Stack trace:

I also had this same issue using this api ,it worked after changing the line
translatedText = Translate.execute(word, Language.ENGLISH, Language.GERMAN);
to
translatedText = Translate.execute(word, Language.GERMAN);
