How to use If Else Statement for this android weather application

How to use If Else Statement for this android weather application - android

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.

android new autocomplete place sdk is unable to shown all locations

I implemented the new autocomplete place sdk in an Android app but it does not show most of places for Nigeria. For example, when I enter spar PH it should show the location SPAR PH, Forces Avenue, Port Harcourt, Nigeria in the suggestion but doesn't. There are other examples that aren't working, too. This was working with the autocomplete Place API but not the new autocomplete .

The Place Picker is deprecated as of January 29, 2019. This feature will be turned off on July 29, 2019, and will no longer be available after that date. You must install the compatibility library to continue using the Place Picker during the deprecation period. Once the deprecation period has ended, the Place Picker will no longer be available for use (including the version in the compatibility library).

In onPostExecute check for activity is running before doing any work.
because onPostExecute may be called if activity was running not more

Try this
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_events_list, container, false);
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(
new BroadcastReceiver() {
#Override

latitude = intent.getStringExtra(LocationMonitoringService.EXTRA_LATITUDE);
longitude = intent.getStringExtra(LocationMonitoringService.EXTRA_LONGITUDE);
new MakeRequestTask().execute(AppSettings.getUserCnic(), latitude, longitude,
mainSdf1.format(Calendar.getInstance().getTime()),
mainSdf2.format(Calendar.getInstance().getTime()));
if (latitude != null && longitude != null) {
mMsgView.setText("msg_location_service_started" + "\n Latitude : " + latitude + "\n Longitude: " + longitude);
}
}
}, new IntentFilter(LocationMonitoringService.ACTION_LOCATION_BROADCAST)
);
//your remaining code here
}

Use following line:
String message = result.optString("message");
// it will returns the empty string ("") if the key you specify doesn't exist
instead of using
String message = result.getString("message");
// it will throws exception if the key you specify doesn't exist

replace getContext() with getActivity() inside your fragment
e.g replace
Toast.makeText(getContext(), "no_google_playservice_available", Toast.LENGTH_LONG).show();
with
`Toast.makeText(getActivity(), "no_google_playservice_available", Toast.LENGTH_LONG).show();`
and
LocalBroadcastManager.getInstance(getContext()).registerReceiver(
with
LocalBroadcastManager.getInstance(getActivity()).registerReceiver(
and so on if any.

Insert coordinates to mysql from android

I have found a tutorial about gps location service.
Every thing works fine.
The next thing I want to write is passing coordinates form app to mysql.
I have tried several tutorial about android mysql but i dont know how to applied them to this code.
What I am trying to achieve is to onLocationChanged send latitude and longitude to database.
Could someone tell me how to do this?
This is the code:
connect.php
<?php
define('HOST','localhost');
define('USER','');
define('PASS','');
define('DB','coordinates');
$con = mysqli_connect(HOST,USER,PASS,DB) or die('Unable to Connect');
?>
insert.php
<?php
require_once('connect.php');
if($_SERVER['REQUEST_METHOD']=='POST'){
$la = $_POST['la_string'];
$lo = $_POST['lo_string'];
$get_result = $con->query("INSERT INTO gps(la,lo) VALUES ('$la','$lo')");
if($get_result === true){
echo "Successfully Registered";
}else{
echo "Not Registered";
}
}else{
echo 'error';
}
?>

You have to make a call via HttpClient to your server and send your data through that as Post with your data encoded.
try{
String data = URLEncoder.encode("la_string", "UTF-8") + "=" +
URLEncoder.encode(data_la.text, "UTF-8");
data += "&" + URLEncoder.encode("lo_string", "UTF-8") + "=" +
URLEncoder.encode(data_lo.text, "UTF-8");
URL url = new URL(URL);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write( data );
wr.flush();
BufferedReader reader = new BufferedReader(new
InputStreamReader(conn.getInputStream()));
StringBuilder sb = new StringBuilder();
String line = null;
// Read Server Response if you have something to do with it
while((line = reader.readLine()) != null) {
sb.append(line);
break;
}
return sb.toString();
} catch(Exception e){
return new String("Exception: " + e.getMessage());
}

You might want to check on how you work with File Contents, first you might want to check if there is a value on the variable textFile that you have set.
The example below illustrates how to append "hello world" to the DriveContents.
try {
ParcelFileDescriptor parcelFileDescriptor = contents.getParcelFileDescriptor();
FileInputStream fileInputStream = new FileInputStream(parcelFileDescriptor
.getFileDescriptor());
// Read to the end of the file.
fileInputStream.read(new byte[fileInputStream.available()]);
// Append to the file.
FileOutputStream fileOutputStream = new FileOutputStream(parcelFileDescriptor
.getFileDescriptor());
Writer writer = new OutputStreamWriter(fileOutputStream);
writer.write("hello world");
} catch (IOException e) {
e.printStackTrace();
}
There is a related SO question - Upload text file to Google Drive using Android that you might want to check out. The answer in the question reminds the OP regarding how to feed the file with contents.
Lastly, you might want to check this github. This code show how to insert the content of the chat into a file and save it to the drive.
Hope this helps.

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.
