EditText value in a Service

Question

I'm building an application in which I use a service to create a background process. but I have a problem. I use an EditText where the user enters a URL, then I will use that url in the service for check the connection to a website every X minutes. But if the user closes the application, the background process crash because the value of the EditText became Null, and logcat give me null pointer exceptions. I pass the value from the activity to the service with an intent, MainActivity code below:

public void onClickReadWebPage(View v)
    {


        if(address.getText().toString().trim().length() == 0)
        {
            Toast.makeText(getApplicationContext(), "URL String empty.", Toast.LENGTH_LONG).show();
        }
        else
        {
            time = String.valueOf(address.getText());
            i=new Intent(MainActivity.this,MyService.class);
            p=PendingIntent.getService(MainActivity.this, 0, i, 0);
            i.putExtra("Address", time);                
            //start the service from here //MyService is your service class name
            startService(i);
        }

and this is the service code:

    @Override
    public void onStart(Intent intent, int startId) 
    {   
        Address = intent.getStringExtra("Address");
        DownloadWebPageTask task = new DownloadWebPageTask();
        task.execute(Address);

        if(report == "false")
        {
            //do my stuff
        }
        else
        {
            //do my stuff
        }
    }

Any suggestion?

is not your problem ( at the moment ) - but really looks wrong: if(report == "false") — ligi, Aug 05 '14 at 08:45

Just save the value of ediText in SharedPreferences and then retrieve them in your service

.See How to use SharedPreferences in Android to store, fetch and edit values
Also Problems using SharedPreferences on a Service (getPreferences doesn't exist on a service)

Thank you, SharedPreferences probably is the correct way to store the URL. – Giacomo De Bacco Aug 05 '14 at 08:49
