I'm wanting to submit an app to the store and I was wondering what pngs I'm meant to submit? I'm confused as there at least 60 different types of scales, for icons, splash screens, large tiles, wide tiles, small tiles. I'm almost overwhelmed with this information. Could someone give me a run through of what is required? for my app, I'm not wanting a small tile, or large tile, or any tile at all for that matter. So I'm seeking some answers as I am struggling to find resources outlining this specific case. I hope I've been clear enough; thanks.
Is this all mandatory? What must I fill out?

Is this mandatory to fill out? What if I don't want any tiles, can I leave it as is?

Please refer to the docs for an example of a minimal required package manifest file for a desktop application.
You only need to reference a 150x150 (large) and 44x44 (small) icon image and I think you may use the same image if you want to.
Otherwise, there is a tool in Visual Studio that creates images of different sizes for you based on a single file.

I am currently developing website and trying to make it responsive. For tests I'm using Chrome Dev Tools Device Mode, where you can set resolution of any device.
The problem is that if you choose e.g. 1920x1080 px and use media queries to style it properly for that resolution it won't fit for user browser since user will have to browse it in full screen mode.
Is there any way to set device resolution to match given resolution browser height and width or are there any good practices of styling in such a way?
Any hints welcomed!
Don't use media queries for precise resolutions. In general, it is better to use one or some max-width and min-width conditions.
One good way is to define media queries for large, medium, small screens. You can check how bootstrap does this for example, with the corresponding breakpoints. Bootstrap breakpoints
For my websites, I start coding for desktop, and then try to reduce the window width until I see that the UI is not good for mobile. Then I take the width and create a breakpoint with it.

I would like to count objects (pipes) from this photo:
Can you help me and give me a general idea of how it should be done? I'm still a beginner and have no previous experience in processing images like this. I've googled it and found something called OpenCv but couldn't go anywhere from there.
If the pipes are always red - take only the red channel from the RGB image.
Have you tried hough transform? It will detect the circles (pipe holes).
You can tweak it a bit to detect elipses as well.
Another approach is to invert the colors of the image and use connected components analysis. The dark holes surrounded with brigth color is an excelent feature
You can also train a classifier on the red channel. Try built in openCV boosted detectors (should be relatively good even with HAAR features. Look at the example of training face detectors. openCV has all the code ready. You just have to cut manually examples of pipe holes.

Im just begining to use polymer and i was testing to make a demo website using polymer components but i felt difficulty on making the pages responsive ?
Should i use css?
Thanks
Yep, you could use CSS. However, web components can be a bit tricky to get responsive because of their nature of re-use and possibly different locations.
Unfortunately, while CSS/media-queries are one solution, it's not the perfect solution. Why? Because the same component, depending on it's location/container may be desired to look/behave differently. For instance, a "voting" component in a primary content section (800PX wide) may display additional information vs the same component in a right rail (200PX wide) where just the question/answers may be displayed.
What we as web developers really need are "element queries", which allow components to react based on their occupying space (rather than the page-level layout). There are articles and polyfills regarding this that may be of interest to you. One can be found here:
http://www.smashingmagazine.com/2013/06/25/media-queries-are-not-the-answer-element-query-polyfill/
IMO, you should focus on Web instead of Mobile, because the native Android browsers before Android 4.4 doesn't support Polymer, even with Polyfills!
Anyway there is a core-drawer-panel, which is a responsive layout you can start with.

i am currently undergoing the branding of a place that is in the outskirts of a major city. the situation at hand is that the place is unknown and not easy to get around, so my associates and i have planned to develop a gps application with specifics eg safari lodges, conference venues of this area and make it possible for people to download it onto their smartphones (nokia,iphone and black berry) and be able to navigate their way around.
the issue is how much would it cost to develop such an application and run it?
need an answer ASAP. thanks a mil.
The answer to this question could be 1000$, but it could be 100.000$ as well. There are so many details to a project like this that must be taken into account that it is almost impossible to answer your question more precisely.
To give an example - consider details like (but not only):
who will supply the necessary content
does the content need to be updated on a regular basis -> CMS
should the app navigate the user around in turn-by-turn style or should it be more like an interactive map
These three details alone would make a huge difference. So, the best thing you can do is contact a company or a freelance developer, brief him precisely on the matter and see how much it'll cost you.

I'm going to create mobile version of website...
What width should I choose for design? I know that every device have it's own screen width and it's really difficult to fit all devices...
I'm really confused (pretty new to mobile websites world), please help.
Thank you.
Your approach will depend on how much effort you want to (or can) put into this and what range of mobile users you want to target. For minimal effort, simply use 100% as KennyTM points out and expect your website to be browsed on screen widths from 128px to 480px . With this approach, you'll also need to avoid 'advanced' xhtml directives such as css and divs (and javascript) because most mobile browsers cannot handle some aspects of these. Plan to use tables to manage layout.
For a more advanced approach, you can use an open source project called WURFL (http://wurfl.sourceforge.net/) which is a database of mobile browsers and their capabilities (screen width, support for div, css, images etc...). It has a jsp tag library called WNG where you write once and the tag lib will render the most appropriate html to match the user's device. I believe there is also a PHP library for this.
Rgds, Kevin.
For this sort of question, I can highly recommend reading the MobiForge developers' guide. Lots of useful advice in there, including how to pick the compromises that inevitably result from mobile development.
