Integrity Unexpected State


This application has registered to handle a URL when sent an intent:

bad Java


IntentFilter filter = new IntentFilter("com.example.URLHandler.openURL");
MyReceiver receiver = new MyReceiver();
registerReceiver(receiver, filter);

public class UrlHandlerReceiver extends BroadcastReceiver {

public void onReceive(Context context, Intent intent) {

if("com.example.URLHandler.openURL".equals(intent.getAction())) {

String URL = intent.getStringExtra("URLToOpen");
int length = URL.length();





The application assumes the URL will always be included in the intent. When the URL is not present, the call to getStringExtra() will return null, thus causing a null pointer exception when length() is called.
