I am going to develop an application for iOS and Android with Xamarin, that has to contain some posts, with the possibility to embed a link to another post (within the app) right into the content. Content should be loaded from some server.
The new Eurosport app can be a very good example of what I am talking about. Many of their news contain links to other news right inside their text, and when you tap one, you see an app's loadscreen, and then the new post shows up.
The deal is, I am almost new to Xamarin (and mobile app development in general), so I got a bit lost, and the more I google, the less I understand. Is it actually possible to achive this with Xamarin (dosen't really matter, Forms or separate platfroms), and what kind of solution it can possibly be? Maybe some frameworks like Prism, or anything else, Deep Links also seem to be sth that I can use?
Absolutely. The way I believe many apps do it is their links are actually links to their website. These links redirect the user to open the equivalent page on the app through a process called Deep Linking.
I can't possibly explain it better than the aforementioned article, so click on it and have a read.

I'm a noob self learning programmer and i'm wondering how can i make an application for mobile. As an example, so you can understand what i need (and easier for me to explain), think of an application where the user can store products and related information by filling forms (an icon, price, name, features, weight...) and then consult stored information.
For me it looks like the best way to create it is by using web related tools like HTML, CSS, MySQL...
The problem i find is that i don't know how to create a web shaped application and then turn it into a mobile app.
I'm sorry if i didn't explain the best way, but hope you guys get my point are able to put me in the right way!
Thanks a lot in advance!!
P.S. Beyond HTML and CSS and a little MySQL i have basic knowledge of JS, C++ and C#.
As a newbie, it's better to do the correct choice at the beginning.
For Android development, the entry point is the developer portal: https://developer.android.com/
The app you've thinking of is quite classic: You won't have troubles to find some tutorials on the web.
You can do that with either SQLite or Firebase Realtime Database, you choose.
I guess, the easiest way will be creating responsive website and then include that in your app as a WebView. However, this might give users the feel that you're just loading the website in a WebView if you don't include some features like, maybe, push notifications, update checker, theme changer, something like that.
You can alos find a lot of easy tutorials and templates to build a WebView app.
P.S.: I myself have made an Android app of my friend's blog by first making a website and then using WebViews.
As a beginner wanting to become more familiar with the android platform, I wanted to create a web client for a website.
Something similar to https://play.google.com/store/apps/details?id=com.krinsen.javadocreader&hl=en
However, I am confused about how the author created the custom UI for the java docs.
To my understanding, there are 2 ways to do this.
One approach is with WebViews. I quickly prototyped a sample of this but I believe (correct me if I'm wrong) that I can't change the UI of the WebView and will have to view the page from the perspective of a browser. Unfortunately, this does not look very well as the website was not mobile optimized and there are inconsistent spacings and odd whitespace.
The second approach is to manually create each View using the different layouts provided by android (LinearLayout, TableLayout, etc). This should create a more custom mobile experience as I can manually construct how each page will look. However, this seems time-consuming as I will need to manually create a different UI page for each page of the website. Also I am confused as to how to pull the data from the website as each new view in the new UI will need the content from the website. Do I need to do HTML parsing to pull the content or is there a better way in the android sdk? What is a good approach that android developers take to extract the different forms of content from a website to redisplay on a android client?
Finally, since I have a very beginner understanding of this situation, am I correct in assuming that most likely the creator of the application mentioned above did something similar to the second approach I mentioned?
What is a good approach that android developers take to extract the different forms of content from a website to redisplay on a android client?
I think the best way is to provide an API for native application. Parsing HTML might look nice untill you need to suppport every change in your HTML page. But if you are not the owner of web-site there is no other choise if only you don't contact owners and ask for an API.
I was trying to write an android app to help people do easier searches on multiple websites like craiglist, ebay ..etc
I am not sure where really to start from, or the name of the technology I would be using. To make it more accurate question, these websites are all forms based that you either post stuffs or retreive stuffs through searching. How can I make my android app actually in which it will ask the user for a item name (that part I know) and then send item name to say craiglist so it gets the results back?
I was thinking of copying the url that is displayed on my broswer when I click search on any of the website and using the same link with string manipulation to include whats needed.
Is this correct? Any other ideas are I know? I am kinda all over the place, but I need a starting point.
Some sites might expose a public API for you to connect with, but that's site specific.
Sites that do not expose such a system can be "scraped", which means you're using string manipulation (as you mentioned) to parse our the data you're after.
Both ways require basic knowledge on how to perform HTTP operations, there are several ways to do this but the easiest way it to use the HttpURLConnection class as described in various tutorials on the web.
Googling for "android http GET POST tutorial" should point you in the right way to get started with your adventure :)
I am about to decide which way to push our smartphone development.
I have read numerous articles about these technologies. I have also created test apps, but wanted to be 100% sure that I get this right.
I am not able to create EXACTLY the same look and feel like native app in PhoneGap because it runs in WebView Controler. And the webish look and feel is as far as I will get with this tech. correct?
(In the example app I have created with PG, the look might be similar, but there is a delay when i click on buttons and the animation is not so fluent as in native apps)
Latest Titanium seems to have changed its approach to WebView, to remedy that lack of look and feel of native apps. My question is (I havent tested this myself). Can I create EXACTLY the same look and feel of an native app with Titanium?
EXACTLY is the key word. I mean can a person tell a difference if app was created with Titanium? because I can definitely tell that app was created with PG.
Final goal is the UX, ppl sense this things, and on smartphones anything that is webish and is suppose to be appish is a bad UX i believe.
Thanks
Compared to PG Titanium is more Native like UI experience but it's kinda problematic for Android.Since it's originally intended for IOS.
Titanium for Android is pretty buggy and can mess you up and the thing that you have to come up with workarounds and if you cant find any then you are stuck.
But if you are okay with that and i can easily advise that Titanium is way to go though it's nearly native (not exactly) which close to exactly.I dont think an average user would understand Titanium .
2) yes, since titanium uses the original UI. your javascript code is wrapped to native Objective c code that creates native elements. only constraint is that your are not as flexible as with real native code written by yourself. but you can write native modules and add them to your projekt. so you're able to expand your project with custom UI too.
I would like to create a custom open source information management application, that I could adapt to practical needs of a psychiatrist. (and also would really like to avoid inventing the wheel). Could someone advise me what would be a good way to start? I have some amateur programming experience (see below), but I have little experience with java and eclipse (which I have set up with Android SDK plugin on my linux PC).
What I would like to achieve is a simple app where I could relatively easily re-program/rearrange information presenting screens. I would like the major development stages to be something like:
Basic framework of the app is done Main information is added
through the programming environment
basic formatting (bold, color, lists) should be supported
I imagine this would be through HTML/CSS markup Hierarchical (not
too deep) screens with concise information about conditions,
treatments; easy, not too cumbersome navigation is a must.
Possibility to attach own notes from android device
on every piece of information (e.g. on medical condition, on medication,
list of differential diagnoses, etc)
A desktop application that allows for easy adding and editing
of the content
initially could be even sqlite manager or something similar
possibility for adding images,
possibility to add rating scales, which would calculate scores
maybe also possibility to print through some android print driver
* in essence I envision this as a sort of an integrated website with a relatively simple database behind it (sqlite?) running on android. My models would be epocrates and medscape apps, but the content would be more specific to everyday psychiatric practice. It would include aspects of psychological therapies as well.
In about a years time, I think, the content would be interesting enough to see whether the app should go on the market.
My (limited) experience:
I am a MD - a Psychiatrist. I have some amateur development experience (php, html, css, Perl, bash, sed, sql, Access and some time ago - AS/400). I would like to start an app that I could modify as I go - in order to have the most useful info at my fingertips, when I need it in my work. I have considered some databases (e.g. HandDB) but my experience with them is that you get very constricted with their user interface and this hinders fast information retrieval when you need it. Adding information can be clumsy as well.
Why I am asking for help here
Most of tasks above seem pretty standard. I imagine that people with lots of programming experience here, probably would be able to point me towards some information that would help me to get started.
Many thanks for considering this :)
Are you going to develop this app? Everything you mentioned can be easily done by reading the android documentation. Although if its you doing the coding i recommend buying a book
You will find a lot of samples and other support in the android doc
Printing can be also setup using Google Cloud print
If you want to open source your application you can always use google code.
You have asked a really broad question here. But i guess the above information is good to get you started.
