Glide Load Image Not Complte

Android-Gif-Drawable

Steps to load Gif images from drawable
You need to move your loading Gif image tores/raw folder of your project
(
if your project don't have raw folder in resource directly then simply make one and put your gif in it )
and then you can simply load your gif with just one line of code
Glide.with(this)
.load(R.raw.loading)
.into(new GlideDrawableImageViewTarget(
(ImageView) findViewById(R.id.image)));
Edits:-
White area in Gif image could be becaouse of streatching gif this is how it look like in my device
Alternatively you can look into this open source library for loading animation

Display large images without lags

I have 4 images set as a background of screens in my application and displaying them cause lags in application. They have 1280x768px and about 70kb. How can I display them without loosing performance?

To use Picasso, simply add this to your gradle:
compile 'com.squareup.picasso:picasso:2.5.2'
And then, in case you have this image on our project folder:
Picasso.with(context).load(R.drawable.landing_screen).into(imageView1);
Instead, if you're downloading the image:
Picasso.with(context).load("http://i.imgur.com/DvpvklR.png").into(imageView);

Problem with Animated gif on Android

I need some advice about animation. I have an animated GIF, but how to put in Android app to be animation. When I put it doesn't move at all. I read something about animation in Android and I need to have pictures for animation. Is there any solution for this ?

Android does not support animated GIFs much. You can use an AnimationDrawable, perhaps defined from frames using a drawable XML file.

you can do it by using GIF image in your app as Splash screen.
Android does not support animated GIFs. so extract gif to png pictures with gif2png and it works with XML.

Adding gif image in an ImageView in android

100 % Work...
1) Add Glide library dependency...
compile 'com.github.bumptech.glide:glide:4.2.0'
2)
imageView = findViewById(R.id.gifImage);
3)
Glide.with(getApplicationContext())
.asGif()
.load(R.drawable.gifImage)
.into(imageView);
just use .asGif() before .load()
