What you expect to be the users location is not what you expect, "current location" will be taken by google as any other address, and google tries to find a place that matches the query.
When somebody told you that "current location" will force google to resolve the location of the user, this is wrong.
You may geolocate the user on your own and then create the link based on the geolocation-result.

The answers of GreatBlakes and Jon Alslund-Lanthén suggest a way that sometimes gives you the right result but that can fail if the language of your user isn't English.
As of 2019, the best way seems to be:

It's a new open source library which provides many cool features out-of-the-box. Specifically with directions, probably the coolest feature is allowing developers to use their overlays (e.g. markers, polygons, etc.) directly as places and waypoints, alongside many other flexible types. No more manual labor...
Here's an example from the docs:
<bs-google-map *bsSafe ...> <bs-google-maps-marker [position]="someCoord" #marker="marker"></bs-google-maps-marker> <bs-google-maps-polygon [path]="somePath" #polygon="polygon"></bs-google-maps-polygon> <bs-google-maps-directions [through]="[marker, polygon, 'Jerusalem', [31.9, 34.7], { lat: 31.99, lng: 35 }, 'Tel Aviv']"></bs-google-maps-directions></bs-google-map>

I'm not sure what the issue was that was preventing you from realising your goals - I tried the code above and it appeared to work - as it was too cold to work in the garage I had a little play and created a small demo; perhaps though you or someone else might find the following useful?
Initially when the call to navigator.getCurrentLocation resolves with the user's location the map loads using the returned position object to form the map centre location. The route to the pre-defined destination is then calculated using the Directions service with a modified options parameter - notably in this instance to hide the default markers. The reason for hiding the markers is because they do not expose any events and thus we cannot bind any listeners to them so we add our own. The added markers allow the route to be dynamically re-calculated ( can also drag the actual route itself )
The text version of the directions is available by clicking on one of the two markers.
The destination is in Birmingham, UK. If you are outwith the UK this might not work immediately without editing this location. Also, a valid API key is required.

Here's an update of your existing code:
// Executes in UI thread, after the parsing process@Overrideprotected void onPostExecute(List<List<HashMap<String, String>>> result) { if (result.size() < 1) { Toast.makeText(getActivity(), "No Points", Toast.LENGTH_SHORT).show(); return; } TextView tv1 = (TextView) getActivity().findViewById(R.id.location1); TextView tv2 = (TextView) getActivity().findViewById(R.id.location2); TextView tv3 = (TextView) getActivity().findViewById(R.id.location3); TextView tv4 = (TextView) getActivity().findViewById(R.id.location4); TextView[] views = {tv1, tv2, tv3, tv4}; // Traversing through all the routes for (int i = 0; i < result.size(); i++) { // Fetching i-th route List<HashMap<String, String>> path = result.get(i); String distance = "No distance"; // Fetching all the points in i-th route for (int j = 0; j < path.size(); j++) { HashMap<String, String> point = path.get(j); if (j == 0) { distance = point.get("distance"); continue; } } // Set text views[i].setText(distance); }}
This code makes a not-so-good assumption: It assumes that the size of result is the same size as views, which in your case should be 4. When you run this code, you may get an IndexOutOfBounds error if you have more than 4 results (which shouldn't happen). Eventually you will want to verify that the size of result is 4, or the number of TextView's you have. If you have any questions or this doesn't work right, just let me know :)
EDIT: To get all distances at once, you can modify your DownloadTask to take in multiple URL's.
Change class definition:
private class DownloadTask extends AsyncTask<String, Void, ArrayList<String>>-
This says that your background operation will return a list of String's.
Modified doInBackground(), which now can process multiple URL's:
// Downloading data in non-ui thread@Overrideprotected ArrayList<String> doInBackground(String... urlList) { try { ArrayList<String> returnList = new ArrayList<String>(); for(String url : urlList) { // Fetching the data from web service String data = Locations.this.downloadUrl(url); returnList.add(data); } return returnList; } catch (Exception e) { Log.d("Background Task", e.toString()); return null; // Failed, return null }}
Then you onPostExecute() becomes
// Executes in UI thread, after the execution of// doInBackground()@Overrideprotected void onPostExecute(ArrayList<String> results) { super.onPostExecute(results); ParserTask parserTask = new ParserTask(); // Invokes the thread for parsing the JSON data parserTask.execute(results);}
Now, you will have to modify your ParserTask code to take in a list of JSON Strings, and not just one JSON String. Just change your ParserTask input parameters and put everything inside a for loop to loop through each JSON String. You will also have to modify the parameter of onPostExecute() to take in a List of whatever is there already, so that way it doesn't process one result, but a list of results. I can't show you those modifications here because it would be way too long, and then there would be no challenge for you :)
EDIT TWO: In getLastLocation() you're only calling DownloadTask with one URL, but you should put four URL's like this downloadTask.execute(url1, url2, url3, url4). Also, since ParserTask still only processes one JSON String, you should take out the four TextView's and the array looping out of the onPostExecute(). To tell the ParserTask which TextView to populate, add a constructor to ParserTask which takes in a TextView as a parameter. Then make an instance variable within ParserTaskthat is assigned in the constructor and used in onPostExecute() to display the distance.
Then, take that TextView array stuff I gave you before and put it in the onPostExecute() of DownloadTask. When you loop through the String results, also loop through the TextView array and pass in the TextView in the ParserTask constructor.
Basically, you're adding a constructor in the ParserTask to tell it which TextView to draw on. When your DownloadTask is finished, you pass it the right TextView for the URL. For example, R.id.location3 for the third URL.
