Download URL after download image with ImageLoad (Android)


Tag : android , By : Jason Vance

fixed the issue. Will look into that further It seems you forget to initialize UserFunctions userFunction, so you're getting NullPointerException when calling userFunction.searchImageActor(mIdActor) inside getDataUrlFromServer()

Image control, override the method that download the image from an uri

wish helps you Yes, since is sealed, you cannot derive from it. Your best alternative is to extend it with attached properties exactly as you have indicated. Another alternative would be to use a behavior, but there's no point. It would not work "better" than an attached property. Good work.

Image download failed when try to download by using IntentService in Android

wish help you to fix your issue When your sending the Sample Result Receiver instance to Your Service class,Your not sending an object of the sample result receiver class infact Your sending a null pointer to the service class.
You must try doing this.
public void click(View view){
sampleResultReceiver = new SampleResultReceiver();
        Intent intent=new Intent(MainActivity.this,MyIntentServiceActivity.class);
        intent.putParceleableExtra("receiver",sampleResultReceiver);
        intent.putExtra("url", TextUtils.isEmpty(edt.getText())?defalut_url:edt.getText().toString());
        startService(intent);
        prb.setVisibility(View.VISIBLE);
        prb.setIndeterminate(true);
    }
