Android : How to use implicit intent from non activity class and in fragment

public class HomeFragment extends Fragment {
ShareLink statLoc;

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {   
    super.onViewCreated(view, savedInstanceState);

statLoc = new ShareLink();
statLoc.execute();
}

The above code is my fragment and am executing a class named ShareLink(). In that ShareLink class I used implicit intent to send data like below

public class ShareLink extends AsyncTask<String, String, String> {

String urlShare = DeviceIdGen.hmUrl;

String statusLoc = null;
public static String locLink = null;
private static String loc = null;   
Context context;    
String locUrl;

protected String doInBackground(String... params) {     

    WebServiceTasks wstShare = new WebServiceTasks();
    return wstShare.getMethod(urlShare);
}

protected void onPostExecute(String result) {   
    super.onPostExecute(result);    

    try {
        JSONObject jResult = new JSONObject(result);
        statusLoc = jResult.getString("status");

        if (statusLoc.equals("success")) {
            loc = jResult.getString("link");                
        locUrl = "My Current Location :" + locLink + "\n\n"
                    + "My Key : " + loc;            

        Intent emailIntent = new Intent(Intent.ACTION_SEND);
        emailIntent.setType("text/plain");
        startActivity((emailIntent).putExtra(
        android.content.Intent.EXTRA_TEXT, locUrl));
        } 
    } catch (JSONException e) {

        e.printStackTrace();
    }}}

But am not able to achieve it. Please help as am a newbie
