How do I get a string from a thread or return a String form a Thread?

Question

Im using a webservice that get a data and stores in a String. I need to use this String but I cant take it. Global variables don't work in Threads. I'm using a traditional Thread new Thread() { public void run() {.

Use LocalBroadcastManager to send and receive data. This way you can avoid memory leak issues.

Here is code for activity

public class YourActivity extends Activity {

    private void signal(){
        LocalBroadcastManager.getInstance(YourActivity.this).registerReceiver(receiver, new IntentFilter("Your action name"));
        Intent yourAction = new Intent(YourActivity.this, YourIntentService.class);
        String string = "someData";
        yourAction .putExtra("KEY_WITH_URL", string);
        startService(yourAction);
    }

    private BroadcastReceiver receiver = new BroadcastReceiver() {

        @Override
        public void onReceive(Context context, Intent intent) {
            String string = intent.getStringExtra("KEY_WITH_ANSWER");
            //Do your code 

        }
    };

}

Here code for thread which download String or whatever

public class YourIntentService extends IntentService {

    @Override
    protected void onHandleIntent(Intent intent) {
        // Download here

        Intent complete = new Intent ("Your action name");
        complete.putExtra("KEY_WITH_ANSWER", stringToReturn);
        LocalBroadcastManager.getInstance(YourIntentService.this).sendBroadcast(complete);

    }

}

You can use Thread instead of IntentService.
