Returning Translated Text From Google Translate Activity

I have developed an Android application that launches a Google Translate Activity using the following code: ... Intent i = new Intent(); i.setAction(Intent.ACTION_VIEW); i.putExtra

Solution 1:

I also am curious to know if this is possible.

Meanwhile, if you need to translate simple text here a class that wrap the Google Translate Http Service.

I've never used it in a production enviroment (read a released app) becouse I'm not sure if it's legal.

So if a Google (employee) will answer to your question..maybe could let me know if this approach is legal.

For convenience here the simple AsyncTask that wrap the Google Translate Http Service:

import java.io.IOException;
    import java.util.Arrays;
    import java.util.Collections;
    import java.util.Locale;
    import java.util.Random;

    import org.json.JSONArray;
    import org.json.JSONException;
    import org.json.JSONObject;

    import android.os.AsyncTask;
    import android.os.Bundle;
    import android.util.Log;

    import com.lus.android.net.RESTClient;

    publicclassTranslatorTaskextendsAsyncTask<Bundle, Void, String> {

        staticfinalprivateStringTAG="TRANSLATOR";

        staticfinalprivate String[] UA_LIST = {

The [RESTClient class] is a wrapper to HttpClient, you can found the source code here
