Depending on how long it takes your thread code to finish parsing http://audiophileradio.stream/Ip.txt, your preferences/append code is also accessing the text variable. What's the possibility of that happening out of order?

mediaPlayer.setDataSource(STREAM_URL);

Have you tried hard-coding the value passed to setDataSource() to see if the reset of your player-related code is correct?

This is unrelated to the problem you are having, but the four if() tests are not as efficient as they could be. You are checking radio's value four more times than is necessary. Consider:

if (radio != null)
{
    text.append(':').append(radio);

    STREAM_URL = text.toString();
    Toast.makeText(this, STREAM_URL, Toast.LENGTH_SHORT).show();
}

Correct MVVM implementation to manually login to website, go to certain link in the website, read information from html element and display it in another View.

That's at least three separate items (that can come together to eventually make your desired app). Have you tried to get each one working independently of the other?

Hi Sifu..

I need some advice to properly implement MVVM with what I'm trying to do.
1) I have a WebView control in a View because I need user to manually login to a website.
2) Once login, it will set a flag to indicate that user has logged in. It will then go to another link in the website and periodically read a html element value.
3) The values read will then be displayed in a table in another View.
4) In the scenario when the user is logged off from the website, it will show the website login page again. And then it will continue to Step 2 and Step 3.
5) The View that has the WebView control only need to be shown for the user to log in to the website. After logging in, the View can be hidden, and only showing the table which contains the values read, which are periodically updated.

I have few ideas on how to implement it but I am not sure if my idea is correct or not.
Idea 1:
Have 2 View/ViewModel pair. 1 View/ViewModel (VM1) to display out the readings read. Another View/ViewModel (VM2) which contains WebView control for the user to login. VM1 will periodically trigger VM2 (by using mediator pattern) to read from the website. As VW2 tries to read from the website, if the user is not logged in to the website, it will go to the log in page. Once the user has logged in, it will go to the webpage that contains the html element and read the value. It will stay in that webpage so that the next time VW1 triggers VM2 to read the value, it can readily do so without user intervention.
Eventhough user may close the VM2's View, the View is not really closed. It is just hidden and the program is still able to read from the webpage in the background.

Idea 2:
Have View/ViewModel (VM1) to display out the value in the table. VM1 calls a service that does the reading of webpage. The service has a WebView control. If the user is not logged in, the service will instantiate a View/ViewModel (VM2) and passing in the WebView control which the user can use to log in. Once the user has logged in, the WebView control is passed back to the service so that the service can continue to read the html element. The service then triggers the ViewModel (VM2) to close the View.

Please advice on what is the correct MVVM way to do what I'm trying to do.
Thanks.

Hello everyone i need to hashed my password when i put it in my login application android and then i need to compare it with my password in my table fos_user of symfony and the password in fos_user is encoders:bcrypt
This is my code:

<?php

     include 'config.inc.php';

	 // Check whether username or password is set from android	
     if(isset($_POST['username']) && isset($_POST['password']))
     {
		  // Innitialize Variable
		  $result='';
	   	  $username = $_POST['username'];
          $password = $_POST['password'];
		    
       $hash = password_hash($password, PASSWORD_BCRYPT);
		  // Query database for row exist or not
          $sql = "SELECT password FROM fos_user WHERE  username = '$username' AND password = '$hash'";
          $test = mysql_query($sql) or die( mysql_error() );
          $row = mysql_fetch_assoc($test);
          if ($hash == $row['password']) 
          {
			 $result="true";	
          }  
          else
          {
			  	$result="false";
          }
		  
		  // send result back to android
   		  echo $result;
  	}



?>

My file config.inc.php is this code

<?php

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "projet_grh";

try {
    	$conn = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    	$conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    	
    }
catch(PDOException $e)
    {
    	die("OOPs something went wrong");
    }

Perhaps you'd be better served here. Once your PHP code is returning the proper credentials, then you can come back to this forum and focus on your Android code.

24-Apr-17 9:55

Store the .rar file in your project's assets folder. During runtime, you can access and save that file to the phone's internal storage or the SD card. As I understand it, RAR is a propriatary format so you can't unarchive it using Java's SDK. Use a third party library like junrar to do the unarchiving.

I am working with googlemap. I have implemented custom marker window, this window contains photo of the marker. I am taking the url of the photo as string and setting it into imageview with thread. However, the code is not syncronized with user. When I have clicked the marker, it shows the photo of the previeus marker that I have clicked. When I did debug, I can see that true url values are coming from background but the setting image into imageview operation is becoming late. How can I solve this problem? I have tried picasso and glide but still same problem.

I don't find the mistake I make

User 1106097926-Mar-17 4:15

Having the coordinates from Android Sensor and try to calculate the distance in Excel according to:

http://andrew.hedges.name/experiments/haversine/

dlon = lon2 - lon1
dlat = lat2 - lat1
a = (sin(dlat/2))^2 + cos(lat1) * cos(lat2) * (sin(dlon/2))^2
c = 2 * atan2( sqrt(a), sqrt(1-a) )
d = R * c (where R is the radius of the Earth)

Enter my two Locations in the calculator (link above) shows me the right result, it is about 6m.

When I calculate it by Excel I get 20Km instead of 6 meters Laugh | :laugh:

I'm strongly assuming that I mix up rad vs. degree but I do not find where I'm wrong.

Excel trigonometric functions expect everything in rad so I adjust lon1, lon2, lat1, lat2 first into rad...

Where I could be wrong, any idea?

Thank you in advance.

N.B: I'm also not sure whether it is ok to use the sensor decimal values directly for trigonometric function, maybe this is the key Point.

[Edit]
c allways Shows me something very near PI, e.g. 3.14159145
