How to achieve a very cool looking on-boarding screen animations like the attached one.And which technology is used for it. is it Lottie Animation/video that developers control on Swipe gestures, or it is achieved by coding.
The animation you have picked is from this source is basically a UI design, which is mainly done by either Sketch or Adobe XD
So the main task is to transform this Sketch App UI Design to Android XML. There is a lot of tutorial in youtube like this from where you can do this.
Then you need to know some basic about XML animation how its work with java. From this video and this link you will get some idea.
Then Finally you need to build an intro slider on your own. You can follow this video and this post
but there is some library also by which you can do this.
You can use App Intro and material-intro-screen

I would like to implement a piece of Android UI that appears in a messaging app when the recipient is typing. Something like this, which appears in the Facebook Messenger Android app:
I imagine the solution is a combination of layout, drawable, and animation resource files, but I am stuck trying to pull all the components together into 1 piece of UI.
What is a high-level implementation of this Android UI?
(I can fine-tune the design and animation effect myself).
The simplest answer here seems like a single high quality gif would be the answer. You could use this gradle dependency https://github.com/koral--/android-gif-drawable which would allow you to get away with a single piece of layout instead of needing to worry about multiple nested views.
Im developing an app and wanted to add some page browsing with those dots to identify your current page like the image below, can someone tell me how is that control called?
Thank you in advance
There is nothing in the Android SDK that provides this "out of the box". It is probably implemented as a LinearLayout holding ImageView widgets, though there are plenty of ways of doing it. If your intention is to use this with a ViewPager, there is an implementation of this UI in the ViewPagerIndicator library and perhaps in other open source libraries as well.
If you really want to see what that app is doing, use uiautomatorviewer to inspect the running UI of that activity and see what widgets are involved.
There is no default Android view for that.
Take a look at this:
https://github.com/JakeWharton/Android-ViewPagerIndicator
In the new Google Docs Android App, the app has an intro slider view in which it shows the different steps of how to use the app - I like it and want to do something similar for my app.
Are there beautiful looking open source libraries to do this? I can think of the following approaches only:
ShowcaseView
I guess I could do it using Tabs, and adjust the look and feel accordingly.
Any other (beautiful) alternatives?
(This question is slightly old, but here goes:)
Another open source Android library that I found that does exactly this (and fairly easily) is AppIntro.
It enables creation of intro sliders that look identical to Google's more recent intro sliders:
vs
Their wiki and their readme nicely describe exactly how to use it.
You can achieve this by using ViewPager.
For each click on "next" button you can change the page in ViewPager.

I am trying to create the UI but I'm having a lot of difficulty just placing controls where I want them to appear on the main screen. For example I want to add a few ImageButtons but they just seem to snap to one corner and I can't seem to add more than one.
Do I need to use a layout or something? Can't I just drag and drop and move the controls around where I want?
I suggest you start by reading a few of the developer tools out there. http://developer.android.com/guide/topics/ui/declaring-layout.html This guide will help you get your feet wet with how to properly layout a screen in Android. There are also a bunch of other great guides on there to help with other aspects of the UI. Even though you use C# in Xamarin Studio, the UI portion is native Android so the guides should still be relevant.
try to use relative layout , its kind of easy for visual studio developer and others too.
details here : http://developer.android.com/guide/topics/ui/layout/relative.html
What I mean to say while you're just getting started with the development and say you add a slider theres a predefined skin for that and you can place it somewhere on the screen, but in some apps there are things like a knob in a place of slider which you can rotate to do the same stuff what the slider does . How do they do that, does it require openGL or something I am not asking for a complete tutorial or something just curious on what stuff goes into building such thing
Mostly, if something is not provided out of the box, you will have to build your own control.
For example, you mention a Knob. That isn't available in the Android SDK. Such a control could prove to be useful.
Here is a tutorial to build such a custom Control: http://go-lambda.blogspot.in/2012/02/rotary-knob-widget-on-android.html
This is an image of the final result from the tutorial linked above:
Here is an example of a custom slider / seek bar: http://permadi.com/blog/2011/11/android-sdk-custom-slider-bar-seekbar/
This should give you a rough idea on how to go about creating your own custom views.
And finally, what I personally find the best possible resource for keeping track of almost all good Custom Views is here: http://www.androidviews.net/
The androidviews.net website has shut down. Android Arsenal is a new website that lists several third party Android libraries.
