I am trying to load a lot of images from server using Android Volley library.
I am curious to, is there any way i can find out the % progress of the image being downloaded.
ImageLoader contains onError and onSuccess only. If not, is there any better library to provide this functionality?
In your situation, you made loading an image as download a file, ImageLoader basically perform a single-session request, does not fulfill your purpose. if you still looking for a library that advantage by Volley but offered a file downloader implementation, then you have Netroid.
you can perform a download request for your image, that make you be capable of showing the progress, once download successfully, you perform loading the local file as a Bitmap to display into ImageView. this approach was indirectly but i think it work for you.

Change your onClick method to below code. You should give the option to choose the external player. @Override public void onClick(View v) { Intent intent = new Intent(Intent.ACTION_VIEW); intent.setDataAndType(Uri.parse("https://youtu.be/jxoG_Y6dvU8"), "video/*"); startActivity(Intent.createChooser(intent, "Complete action using")); } ...
I recommend you to use DeferredResult of Spring. It´s a Future implementation, that use the http long poling technique. http://docs.spring.io/spring-framework/docs/3.2.0.BUILD-SNAPSHOT/api/org/springframework/web/context/request/async/DeferredResult.html So let´s says that you will make a request, and the server it will return you the deferredResult, and then your request will keep it open until the internal process(Hibernate)...

In Java, you cannot write executable statements directly in class.So this is syntactically wrong: for(int i=0; i<10; i++) { this.colorList[i] = this.allColors[this.r.nextInt(this.allColors.length)]; } Executable statements can only be in methods/constructors/code blocks...

If you use plain spark you can join two RDDs. let a = RDD<Tuple2<K,T>> let b = RDD<Tuple2<K,S>> RDD<Tuple2<K,Tuple2<S,T>>> c = a.join(b) This produces an RDD of every pair for key K. There are also leftOuterJoin, rightOuterJoin, and fullOuterJoin methods on RDD. So you have to map both datasets to...
You shouldn't use constant a pixel-to-unit conversion, as this would lead to different behavior on different screen sizes/resolutions.
