How would I make animations like this and this? I couldn't find any result on Google showing me how to do it. I have absolutely no idea of how to go about making such animations.
Any help would be greatly appreciated.
Animation in the links implemented with animated gifs/jpegs. In order to make such animations in Android you will have to:
Create individual frames of your animations and save them in .png files
Create AnimationDrawable and add your frames there
Use your new drawable where you'd like to see an animation
Edit: different way was described here

I would like to create this animation, i already checked several blogs but did not find one that addresses what i want. Some help would be appreciated thanks. animation.
Try using Lottie from airbnb. It's a library that renders affter effects animations in real time. Here's the setup guide
Creating that kind of animation via code is tedious , if you can find the gif of it you can just add it to the imageview , how you can achieve this you can find on the given link

I searching for a way to animate views via xml, I am really lost in this part of UI programming.
Can anybody explain to me step by step how to do this?
You can animate android views by using Animation resources.
With xml animations you can set different properties e.g duration, rate of change (interpolator).
AndroidHive has a very good tutorial with a nice set of animations
http://www.androidhive.info/2013/06/android-working-with-xml-animations/
From my experience with xml animations, you won't know what you want until you've played around with different properties.

Update:
Interpolators as well are also important,they allow you to achieve a lot more smoothness. But misusing them can also be expensive so be make sure its necessary.

This blog also gives a quick peek into the actual effects of interpolators:

I have gridView which has lot of images and on clicking the edit button, I want the images to wobble just like : how to create iphone's wobbling icon effect?. Appreciate any pointers to solve this issue.
You can start off by modeling the wobble effect as a combination of Animations that Android provides. You can then extend an ImageView and use an AnimationSet of this combination of Animations.
You can create an xml that defines how the ImageView will be animated, load the animation in code referencing this xml and then apply it. A brief documentation here.
I know basic level Android, but haven't had done animation before. Moreover, I don't have any clue as to how can I create custom Geometrical objects like triangle, Hexagon, etc.
Moreover, I don't know anything about doing animation in Android. I'd like to have relevant tutorial links or blogs which can help understand the basics and preferable a sample code for "Rotation" animation.
Thanks in advance.
http://code.google.com/p/nehe-android/ (the code is best documentation ^_^)
but it is for open gl custom objects on top of your view/surface view, it is commonly used in games.
If you want to do just rotation for Button, there are http://developer.android.com/reference/android/view/animation/Animation.html and subclasses of it (RotateAnimation and so on), you can even do a custom one. By this way you can do awesome user experience for application which use default android controls.

I'm starting out with Android development, and I'm kind of stuck. Basically, I have a layout with dynamically added ImageViews, and I want to have the ImageViews change their image every once in a while. However, I'd like to add some sort of transition or changing animation, like a flip or a flash.
I don't really know where to even start to look for an answer to this question. Any help is greatly appreciated.
The android framework has this totally covered:
http://developer.android.com/guide/topics/graphics/view-animation.html
Basically, you are looking to define "tween" animations between your drawables (imageviews). After you define your animations you can even define a set of drawables to show one after the other using frame-animation.
Check out the following for all the gory details:
