Displaying .gif in Android? - android

I want to know how to "easily" display a gif image (animated) ...in android.
Is there a custom library or something like that, maybe a .jar I can download and use it to link a .gif resource and display it an an activity ?
I know this has been asked a lot of times on SO, but there's not one easy solution, and a beginner like me could get lost easily.
I'm looking for something like what Picasso does in displaying images from URLs...
Google search didn't find me anything, only empty questions with half hearted not working/ deprecated answers.
As a last resort, here I am.
So, is there an easy way to display .gifs in an android ?
(Possibly, as easy as displaying text or an image ?)

Follow the below tutorial which explains how to use gif image in android:

How to load images from internet in android app quickly?

I'm a beginner in android and i want to load some images from internet in my app. I heard about libraries such as Glide and Picasso. Can anyone please tell me which library is the best.
In your title you use the word "quickly". Theres no such thing, unless you have a cache implementation. As you pointed out those two libraries help in retrieving images from the web and displaying them into imageView, also support cache features so that images previously displayed can load faster in the near future.
Simple example of Picasso:
Picasso.get().load("http://i.imgur.com/DvpvklR.png").into(imageView);

According to this article here both are really nice to be used , but I would suggest Picasso because it just updated to 3.0 + it is lighter than Glide when it comes to :
library size and method count .

pdf view in gridview android

I would like to ask advise if displaying pdf inside gridview instead of image is possible. I have tried to display list of websites in gridview using webview. Now, I want to make it a list of pdf files inside gridview. Normally same with if you open your folder in your linux laptop and have the thumbnails of your pdf, things like that. I want to achieve that in my application. I would really appreciate any of your advice, no codes needed cause i will handle it my self. I just want to have some theories. thanks and HAPPY NEW YEAR GUYS
I think what you're going to have to is convert the pdf's into a bitmap first, then load into an ImageView, check out this post and also look into other pdf rendering libraries for Android.

Android Image Processiing

In my application I want to capture an image and compare it with a stored image to know if they are similar.

Display image using a RSS feed

I have an application in which use a RSS feed reader. My problem is that I don't know what is the best way to display an image. The closer I could get was to pull the image description (). I know I could parse this String by myself and get the image url, but I was wondering if there is a more elegant way to solve this issue. I tried using the SAX and the DOM classes, but I couldn't figure it out.
Best way to DISPLAY the image? I'm not sure if that's actually what you're asking, but just use an ImageView. Use an AsyncTask to download the image in the background, and then create a new Drawable from that downloaded image (might even want to cache it to storage) and set that as the source for the ImageView.
there is a library for downloading and caching images in background from the URL
https://github.com/koush/UrlImageViewHelperSample
=)
Are you asking how to get the image URL from the XML RSS feed? There's nothing built into the SDK that's going to help you parse the XML, other than SAX or DOM which you have already noted. There is a learning curve to those, but they are reasonable approaches.
There's a project called ROME that is an API for robustly parsing all sorts of feeds, including RSS. You could import this library into your android app. Note that this library has other dependencies, so you'd have to import them also. I haven't done it personally, but I have heard of people using ROME in Android apps, so it's doable.
Or more simply, if you just want the image URL and you don't need a complete feed parser, you can use java.util.regex to parse out the fields you want.
If you are asking how to display the image after you have the URL, kcoppock's answer explains it.

Android: How do a display a large animated gif given a url?
And checkout the BitmapDecode given in APIDemos.
As far as I know, Android doesn't support GIF images' animation, so you'll perhaps have to try the other way around: create separate images for each state of your current GIF, and animate them using Android 2D animation.
This is manual, and time consuming, but sadly this is what I can suggest.
