400 error - The given location is invalid - json

Question

I am trying to retrieve JSON data via an API and parsing it into my Android. I am trying to log the JSON data retrieved but I keep getting a "400 error - given location is invalid." The parameters to access the API seem correct but I am not sure why I can't retrieve the data.
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
temperatureLabel = (TextView) findViewById(R.id.temperatureLabel);
timeLabel = (TextView) findViewById(R.id.timeLabel);
refreshButton = (ImageView) findViewById(R.id.refreshImage);
final double latitude = -104.8319;
final double longtitude = 39.7294;
refreshButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
getWeatherForecast(latitude, longtitude);
}
});
getWeatherForecast(latitude, longtitude);
}
public void getWeatherForecast(double latitude, double longtitude) {
String apiKey = "SECRET-KEY;
String forecastURL = "https://api.darksky.net/forecast/" + apiKey + "/" + latitude + ","
+ longtitude;
if (isNetworkAvailable()) {
//Build and HTTP request
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder().url(forecastURL).build();
//Make an Api call
Call call = client.newCall(request);
call.enqueue(new Callback() {
#Override
public void onFailure(Request request, IOException e) {
runOnUiThread(new Runnable() {
#Override
public void run() {
alertUserError();
}
});
}
#Override
public void onResponse(Response response) throws IOException {
try {
String jsonData = response.body().string();
Log.e(TAG, "JASON DATA" + jsonData);
if (response.isSuccessful()) {
mcurrentWeather = getCurrentWeatherDetails(jsonData);
// You want to update the display In the UI.
runOnUiThread(new Runnable() {
#Override
public void run() {
updateDisplay();
}
});
} else {
runOnUiThread(new Runnable() {
#Override
public void run() {
Toast.makeText(getApplicationContext(), "API call failed", Toast.LENGTH_LONG).show();
}
});
}
} catch (IOException e) {
Log.e(TAG, "Exception Caught");
} catch (JSONException e) {
Log.e(TAG, "JSONexception Caught");
}
}
});
} else {
alertUserError();
}
}

Answer 1

If you are trying to check what request you send to the API and what the API sends to you, then you should implement OkHttp logging interceptor. It's simple and easy to work with it.

Answer 2

First of all, I have deleted your secret key from your answer and replaced it with "SECRET-KEY". DarkSky is only free 1000 requests per day, so someone could grab that key and reuse it. You'd have to pay for it.
I would to go to https://darksky.net/dev/account and reset the secret key to avoid risks.
Second, your coordinates are swapped. You currently have
final double latitude = -104.8319;
final double longtitude = 39.7294;
String forecastURL = "https://api.darksky.net/forecast/" + apiKey + "/"
+ latitude + ","
+ longtitude;
That result of:
https://api.darksky.net/forecast/SECRET-KEY/-104.8319,39.7294?exclude=minutely,hourly,daily,flags,alerts
is then "400, Location invalid" because there is no location in the world with latitude -104 and longitude 39.
The correct one is
final double latitude = 39.7294;
final double longtitude = -104.8319;
Then your urlString is:
https://api.darksky.net/forecast/SECRET-KEY/39.7294,-104.8319?exclude=minutely,hourly,daily,flags,alerts
which outputs in the browser:
{
"latitude":39.7294,
"longitude":-104.8319,
"timezone":"America/Denver",
"currently":{
"time":1583068320,
"summary":"Mostly Cloudy",
"icon":"partly-cloudy-night",
"nearestStormDistance":9,
"nearestStormBearing":145,
"precipIntensity":0,
"precipProbability":0,
"temperature":37.32,
"apparentTemperature":33.14,
"dewPoint":18.62,
"humidity":0.46,
"pressure":1011.5,
"windSpeed":5.24,
"windGust":7.61,
"windBearing":157,
"cloudCover":0.87,
"uvIndex":0,
"visibility":10,
"ozone":309},
"offset":-7
}
P.S: Notice I included the exclude query item to shorten the response to show the example. Delete that part and you will have all the response, with minutely, daily and so on fields.
