Display a dialog on booking detail activity while the users click on the cancel booking. In detail, if the booking is confirmed by professional the cancel booking status within 24 hours charged 20%; if out of 24 hours charged 30%; else the booking are pending not charged.

the photo taking function with camera or selecting pictures from library. In general, once the users click on the add photo, a dialog should be sliding in from bottom of the screen. Lastly, I created a Cloudinary account to upload an image to the cloud

Firstly, added permissions camera and wrote an external storage into manifest file. Secondly, created a custom bottom dialog. OnActivityResult is very important as we can get image Uri after taking pictures or selecting pictures

Once the users click on nearby location the result should get the current longitude and latitude. Moreover, alert dialog needs to be prompted out when the user does not turn on the GPS.

I added permission on Android Mainifest in order to retrieve the current location. Also, I appended LocationListener into the project as well.

Sample code getLocation:

     public Location getLocation() {
         try {
             locationManager = (LocationManager) mContext
                     .getSystemService(LOCATION_SERVICE); 

             // getting GPS status
             isGPSEnabled = locationManager
                     .isProviderEnabled(LocationManager.GPS_PROVIDER);

             // getting network status
             isNetworkEnabled = locationManager
                     .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

             if (!isGPSEnabled && !isNetworkEnabled) {
                 showSettingsAlert();
                 // no network provider is enabled
             } else {
                 this.canGetLocation = true;
                 // First get location from Network Provider
                 if (isNetworkEnabled) {
                     if (Build.VERSION.SDK_INT >= 23 &&
                            ContextCompat.checkSelfPermission(mContext, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED &&
                             ContextCompat.checkSelfPermission(mContext, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
                     }
                    locationManager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER,
                            0,
                            0, this);
                     Log.d("Network", "Network");
                     if (locationManager != null) {
                         location = locationManager
                                 .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                         if (location != null) {
                             latitude = location.getLatitude();
                             longitude = location.getLongitude();
                         }
                     }
                 }
                 // if GPS Enabled get lat/long using GPS Services
                 if (isGPSEnabled) {
                     if (location == null) {
                         locationManager.requestLocationUpdates(

Facebook Login on Android App

Facebook login feature. Be specific, once the users have successful log on, the application should get the user profile picture, ID and name

Once the users click on the Facebook login button, the authentication is done via the referenced Facebook SDK library. To successfully run the Facebook Login, I have to add in Android development key hash to my Facebook developer profile. Facebook uses the key hash to authenticate interactions between the app and the Facebook app. To generate key hash I had installed openSSL then go to command line to get the key hash from the keystore

Following the Facebook developer guideline, there was the key hash discrepancy problem while logging into the Facebook. To generate key hash again, I had installed openSSL then went to command line to get the key hash from the keystore
