My onCreate from MainActivity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
String apiKey = "*********************************";
double latitude = 37.8267;
double longitude = -122.423;
String forecastURL = "https://api.forecast.io/forecast/" + apiKey + "/" +
latitude + "," + longitude;
if (isNetworkAvailable())
{
OkHttpClient client = new OkHttpClient();
Request request = new Request.Builder()
.url(forecastURL)
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Call call, IOException e) {
}
@Override
public void onResponse(Call call, Response response) throws IOException
{
try
{
String jsonData = response.body().string();
if (response.isSuccessful()) {
mCurrentWeather = getCurrentDetails(jsonData);
runOnUiThread(new Runnable() {
@Override
public void run() {
updateDisplay();
}
});
}
else
{
alertUserError();
}
}
catch (IOException | JSONException e) {
Log.e(TAG, "Exception caught: ", e);
}
}
});
}
else
{
Toast.makeText(this, R.string.networkUnavailable, Toast.LENGTH_LONG).show();
}
}
And from updateDisplay()
private void updateDisplay() {
mTemperatureLabel.setText(String.format("%d", mCurrentWeather.getTemperature()));
mTimeLabel.setText(String.format("At %d it will be", mCurrentWeather.getTime()));
mHumidityValue.setText(String.format("%s", mCurrentWeather.getHumidity()));
mPrecipValue.setText(String.format("%d", mCurrentWeather.getPrecipChance()) + "%");
mSummaryLabel.setText(mCurrentWeather.getSummary());
Drawable drawable = ContextCompat.getDrawable(this, mCurrentWeather.getIconID());
mIconImageView.setImageDrawable(drawable);
}
btw, the error that i got:
