How to use If Else Statement for this android weather application

When the code below runs, it shows the temperature in degrees.
public class MainActivity extends AppCompatActivity implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String APP_ID = "80e4eede56844462ef3cdc721208c31f";
private static final int PERMISSION_ACCESS_COARSE_LOCATION = 1;
private GoogleApiClient googleApiClient;
private TextView textView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
textView = (TextView) findViewById(R.id.textView);
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
!= PackageManager.PERMISSION_GRANTED) {
ActivityCompat.requestPermissions(this, new String[] { Manifest.permission.ACCESS_COARSE_LOCATION },
PERMISSION_ACCESS_COARSE_LOCATION);
}
googleApiClient = new GoogleApiClient.Builder(this, this, this).addApi(LocationServices.API).build();
}
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case PERMISSION_ACCESS_COARSE_LOCATION:
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// All good!
} else {
Toast.makeText(this, "Need your location!", Toast.LENGTH_SHORT).show();
}
break;
}
}
#Override
protected void onStart() {
super.onStart();
if (googleApiClient != null) {
googleApiClient.connect();
}
}
#Override
protected void onStop() {
googleApiClient.disconnect();
super.onStop();
}
#Override
public void onConnected(Bundle bundle) {
Log.i(MainActivity.class.getSimpleName(), "Connected to Google Play Services!");
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION)
== PackageManager.PERMISSION_GRANTED) {
Location lastLocation = LocationServices.FusedLocationApi.getLastLocation(googleApiClient);
double lat = lastLocation.getLatitude(), lon = lastLocation.getLongitude();
String units = "imperial";
String url = String.format("http://api.openweathermap.org/data/2.5/weather?lat=%f&lon=%f&units=%s&appid=%s",
lat, lon, units, APP_ID);
new GetWeatherTask(textView).execute(url);
}
}
#Override
public void onConnectionSuspended(int i) {
}
#Override
public void onConnectionFailed(ConnectionResult connectionResult) {
Log.i(MainActivity.class.getSimpleName(), "Can't connect to Google Play Services!");
}
private class GetWeatherTask extends AsyncTask<String, Void, String> {
private TextView textView;
public GetWeatherTask(TextView textView) {
this.textView = textView;
}
#Override
protected String doInBackground(String... strings) {
String weather = "UNDEFINED";
try {
URL url = new URL(strings[0]);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
InputStream stream = new BufferedInputStream(urlConnection.getInputStream());
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(stream));
StringBuilder builder = new StringBuilder();
String inputString;
while ((inputString = bufferedReader.readLine()) != null) {
builder.append(inputString);
}
JSONObject topLevel = new JSONObject(builder.toString());
JSONObject main = topLevel.getJSONObject("main");
weather = String.valueOf(main.getDouble("temp"));
urlConnection.disconnect();
} catch (IOException | JSONException e) {
e.printStackTrace();
}
return weather;
}
#Override
public void onPostExecute(String temp) {
textView.setText("Weather temperature is: " + temp + "°");
}
}
}
Can someone help me on how to use the if and else statements to make it so that if the temperature is below a certain degree, the user interface will display some text and if it's above that certain degree, it will display a different text?

#Override
public void onPostExecute(String temp) {
textView.setText("Weather temperature is: " + temp + "°");
if (temp < someValue)
//doSomething
else
//doSomethingElse
}
This should be intuitive enough.

first of all you will receive the temp as double value
don't convert it to string, replace this
weather = String.valueOf(main.getDouble("temp"));
to
double weather = main.getDouble("temp");
and do this
#Override
public void onPostExecute() {
if (weather < yourValue)
//yourCode
else
//anthorCode
}
OR if you want to convert the temp value to string just add this
#Override
public void onPostExecute() {
if (weather.equals("yourValue"))
//yourCode
else
//anthorCode
}
and i don't recommended this.

Getting incoming calls for an hour only using Twilio

I have implemented Twilio in my android app for outgoing and incoming calls. But I'm facing an issue while getting incoming call with the background service. The issue is that I get calls in first 30-40 mins only. After sometime phone stops getting incoming calls. I tried so much. Please respond me soon. I'm sharing code with you too.
I get token from a background service which generates token after a time period.

from my understanding when your position strays off the calculated route, it should trigger a route (re)calculation. I have tried it and I received both onRerouteBegin and onReRouteEnd callbacks. From my observation staying on route does not trigger any re-routing.

Android - cast screen to chromecast via custom app

I need to do the same thing of the Chromecast App (com.google.android.apps.chromecast.app) "Mirror screen" functionality:
pressing a custom button the app asks to select the chromecast device to stream to and then start the screen mirroring to the selected chromecast device.
Actually this feature is not documented anywhere. Have i to use the Presentation class?
Reading logs of the Chromecast App i discovered the following receiver app ids:
app id E8C28D3C
app name Backdrop
app id 674A0243
app name Screen Mirroring
How can i do that?
This is my code:

You cannot do that from your own app, currently there are no APIs available for developers to start the cast mirroring from within their apps and it should be done manually by user; this may change in future but that is the current status.

Seems you only need not set up any custom Presentation screen and mirroring will be carried out by default:
