Basically i need 2 apps that work on both Android/IOS with a simple sign in button and 5 push notifications that can be dowloaded for a little project.
The conclusion I reached was html? and some way to let the user download the files without needing hosting etc.
perhaps someone knows of a more efficient way to do this? or since its non profit get some skeleton code for each os and then just add buttons from x code and android api?
I am not really sure what you are asking but, you can use 'Phonegap' which is cross platform and can use web development languages such as html, JavaScript, and css.

I'm planning to create a BLE (Bluetooth Low Energy) mobile app for both iOS and Android devices. (iOS 11 or above / Android 6 or above)
I and my friend used both Java and Swift.
Although we searched about Xamarin or PhoneGap App,
we wanted to use our previous working environment (Xcode/Android Studio) as possible, not spending time on learning new tools.
So we want to work on a BLE app and we want to make it work on both Android and iOS. Currently, we are making the same thing using Swift and Java.
Since the UI part overlaps for both platform, we wish to ask these questions, please.
If we use Swift and Java separately, we noticed that when a picture is changed, we have to update both to each separate code.
For example, we wanted to change the round button to a square button shape. Currently, we upload the same picture to the GitHub repository respectively. So we felt something is not efficient and we want to ask is there a better way to change both sides of the app.
Solutions which require prices, like adding Amazon Web Service S3, is also welcomed.
We are creating the same UI for both platforms using Swift and Java. Since the UI, button, etc (the interface parts) overlaps for both app, is there a way to code the same UI so both of us don't have to spend time for working the same thing?
Maybe something like Xamarin could be one way, but I want to hear various advice, please.
Why not just put the images in a common folder in source control that both builds can access it? That's the common way of doing it. Using S3 (or any other server) will work if you want to download it at runtime, but since you tried checking it into source control it seems like you want it part of the build.
As for the UI- native Android and iOS have completely different UIs and ways of working with it. Really unless you want to go with an html app, you're going to write two different UIs. The UIs are the least sharable part of a mobile app. At least for business logic you have a few options (worst case you can always use C, which runs on both).
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.
We have an upcoming [big] project, involving a series of mobile apps. Unfortunately we're still new to this market. Our biggest problem is not learning something new, but rather having to develop the same app twice which means approx ~ twice the cost and Hence we're trying to find a cross platform solution.
Since our expertise is in C# and .NET we are very interested in MonoDroid/Touch, and from what I've read that it is a mature framework.
However it is not exactly cross-platform (or am I wrong ?) and so we turned to Phonegap, which lets you build mobile apps with js, css and html which are technologies which we feel comfortable using.
Our apps are going to be very data intensive and might also require to be "invoked" by the server, i.e. there might be 2-way communication between the server and the app.
and so my question, given these kind of apps would you suggest phonegap or monoTouch/Droid?
Thanks in advance.
Monotouch is NOT cross platform. It allows you to create reusable elements, but you can't build once and deploy to all platforms, especially if your project is really as complex as you are making it sound.
I don't know much about phonegap. I've always steered clear of it. It might have changed since I looked at it last, but as I gather its not very robust and doesn't create very good apps, especially (again) for a complex app.
There is another cross platform framework called Titanium, but similarly to the both above its not great. There is more support for it every day, but it is missing some key components and you tend to get so far into a project and realise that you're not able to get any further.
My answer, which you're not going to want to hear, is that you should do it for each platform separately, and charge your client as such.
Creating a mobile app cross platform is like creating a t-shirt that will fit everyone. Ok, so you can make it stretchy, and you can design it in a way that will "suit" everyone, but what you'll end up with is something that is going to be too big or too small, and no-one will enjoy.
iPhone, android, iPad, blackberry, windows phone 7, bada etc etc they're all VERY different platforms. Just because they're both mobile phones doesn't make them similar at all. The way that the UI is designed and displayed is varyingly different, and the way you interact with the hardware (and ultimately the user) is also different. Case and point - iPhone as you go down views you create a navigation stack which you navigate using a back button in the title bar (which has the title of the current view in it). Android you navigate with the back button on the device and the action bar is used for the app title and other "action buttons".
To this end I would suggest, if you REALLY don't want to do everything natively (which is definitely the best option) then I would suggest looking at Monotouch and creating two apps with reusable components.
With PhoneGap you will create a web application. It can look like a native app, but it's really a web app running inside a browser object.
You'll be programming the client HTML and javascript, just like any other client side web app. You can create ajax calls to the server to get your data and do all your usual C#/.Net stuff there.
With Mono, you will create a clients side application, and you can program that client in C#/.Net.
PhoneGap will be more or less free and can be used for other platforms than Windows, iOS and Android as well, though you'll have to setup environments for each version. You can compile for all platforms in the cloud, but that'll cost you money.
MonoTouch/Droid will set you back a few hundred dollars.
For each platform, you will have to do some extra tweaking. Probably giving it a native look and feel, call different API's, etc.
I would personally advise the Mono route, since you know C#/.Net already. It'll give you results faster. Make use of the free trial for MonoTouch and see if it's something for you and if it's worth buying ($698 for both 'touch and 'droid).
It depends.
I agree that going native gives you the best possible performance and user experience. It's certainly the only feasible option if the app has a demanding UI. But if the app is more informational (perhaps displays news feeds for example) then a hybrid HTML5 app could be the go. The support of HTML5 within a UIWebView on iOS has some quirks in the older iOS versions so tread with caution. And on Android and other platforms, HTML5 isn't quite there yet. Certainly not on older hardware that doesn't have the grunt or browsers with suboptimal javascript engines.
With your .NET background, I suggest you have a look at http://www.vsnomad.com and evaluate it for yourself. Throw a quick demo together and see how it holds up. Otherwise, yeah, go the native route.
I would like to create an application that support in both Android and iPhone.
It will be a interactive system for people to chat,share photos, etc.
So, it will consist lo-gin system, and all information for users will stored in mysql.
The question is here, should I write two sets of code for Android and iPhone or use some cross platform tools such as Phonegap + jQueryMobile for development.
1)I am wondering if html + css + javascript can complete all the functions that I want to include in this application if I use Phonegap.For example, how to handle the data transfer when loading data from db, should I create many .html for different pages. And the performance of using Phonegap...
2)Also, how about the time of development. Suppose there is one developer for Android, and one for iPhone. If we develop separately, we cannot help each other. On the other hand, web may be easier and we can research on this together.
3)Then, for the UI, it is easier for native language. But it is much difficult for web to make the things like mobile application.
I have asked a lot of questions. But I really think about this kind of issue for a long time and this is the time for me to have the decision.
Can anyone help me and give me some idea? Really thx....
Consider these Factors & Make your own wise decision,
which coding technique are you familiar with (HTML, CSS, JS) or (Java, C#).
For your First Question about data transfer from db,(your question is not clear internal db or server side db) if internal db Here is My QuestionI couldn't find the solution with the given answers, Help me if you can solve the same.(if you are talking about server side db) both for native & Cross platform it has to be achieved by API's
Time of Development is less in PhoneGap, when consider for both platforms since you are coding for both platforms simultaneously.
UI is Easier in Native ONLY when you go with Default styles,
For example consider yourself adding a Customized Button in *.png format.
you are gonna add single button multiple times in multiple sizes. If you wanna achieve clicked or Hover Effect you are Gonna add 2 more Customized Buttons. Which makes totally 3 images for single click for single Screen & Single Orientation, to achieve Correct Quality, u have to add same image in different sizes in ldpi, mdpi, hdpi, x-hdpi, no-dpi which finally brings you 5x3=15 images for single Button.(imagine the size of your app). Finally you have to add few lines of Codes to achieve Clicked effect
The same can be achieved in CSS with few lines of Codes(hardly 5 KB). Many animations also can be achieved easily with js.
UI can be changed when ever you want with change in few lines of codes.UI - PhoneGap Wins your app runs in Browser, both Android & iOS use the same browser engine Webkit, but still significant differences even in Webkit
Here are few more issues in PhoneGap,
Performance Native wins. In PhoneGap your browser has to load js, CSS which gives you notable delay, which cannot be ignored. If you want awesome UI go with CrossPlatform. To achieve performance choose Native.
Finally time to take decision.
It depends on what your requirements are. Evaluate if all your requirements are possible with Phonegap. For a list of supported features see: http://phonegap.com/about/features
Note that you can only use the native phone functionality that phonegap provides.
The development time depends on various factors, such as complexity, size of project and developer skill. I think the main difference here is developer skill, as the complexity and size of project are the same.
This is a tradeoff you have to make. An example phonegap application can be found here:
http://coenraets.org/blog/2011/10/sample-application-with-jquery-mobile-and-phonegap/
1.If you build application using cordova with more page, you app will get slow and some time it will get more bugs of design. So it
is better if you use single html page with different dives for each
pages and use "display: none;" from your java script or JQuery to
show and hide you current pages.then your application will more
fast.
there a lot of plugins in cordova those are supporting for both iOS and android so you don't need a iOS developer or android
developer if you have proper html and css design like responsive web
site.
UI won't be problem if you build a responsive html pages using bootstrap
I've written some simple online games using purely HTML5 and JavaScript. Nothing fancy, no server side stuff involved, essentially each game is just a single .html (which includes javascript and css) and some .png and .jpg images.
Now, this kinda works on mobile devices as well (android/iphone/ipad) by just surfing to the particular page, but I guess a dedicated app would work better / be more convenient on these devices.
I have exactly zero experience developing for iOS or Android, so maybe this question is too complicated to fully answer right away, but:
Is it possible to create an app for Android, and similarly for iOS (iphone/ipad), based on my html page, other than basically rewriting the entire game for those particular platforms?
If yes, how do I go about this? What would be the easiest way? Is there a ton of Android / iOS knowledge required, or is there some kind of generic "conversion" that wraps my html page (+required images) into a mobile app?
I guess that phonegap would perfectly fit your needs.
Hope it helps
Appcelerator can do that. It builds native Android apps and iOS. The language is based on HTML5 and JS so I think it can help you.
