Making a App for tablets with certain requirements - android

I need to create a app that will run across Android and IOS, although i would like to avoid the native languages of both and only use JS/HTML/CSS, after digging a lot online i think that the solution would be to use Phonegap and Ionic Framework
The app is not complicated i just have to create simple drag and drop games that the user can review at any point and make changes to them.
The whole point is for a medic to create profiles for the patients and be able to consult them at any time.
Now my question is simple: will this do enough? or should i look into anything else?

Phonegap or Cordova are good solutions for you, then you have to build your UI with HTML. For drag & drop you could use jQueryUI

In my opinion, you have to go through with the PhoneGap/Cordova plugins
also, and go through with the which IDE is used for Development the Application like Xamarin,NetBeans etc.

Dynamically alter App Icon on iOS and Android

I'm fairly new to Flutter but have found that it fits most of my design needs for iOS and Android. But, I've been unable to find a way to dynamically change the app icon.
In Swift, you were able to change the app icon from inside the actual app allowing for some pretty neat customization. A Medium article discussed this back when it first came out for iOS 10.3.
Does anybody know of any way to do this in Flutter, or will I need to make a custom package to do this?

Maybe this would help. Here's a plugin too.
https://pub.dev/packages/flutter_dynamic_icon
I don't believe this is currently supported, and probably won't be by the flutter team although someone could theoretically write a plugin to do it. However, most of the configuration needs to be done natively anyways, so I don't know how much value the plugin would provide other than doing the call to setAlternateIconName.
What you should do is write the code directly in iOS as you would for a native iOS app, but expose a MethodChannel to the dart side which would allow you to control it from flutter.

Can i build an application with basics of a programing & codes researching?

Can I build an application with basics of a programming & codes researching ?
my question is that can I build an app with the basics of a programming language like Python and researching on internet on codes that I will need to use on my application.
Thank's.
Yes, you can do. You've to just brush up life cycle of app in iOS & Android e.g. view and activity. All languages are same in semantics except syntax.
Yes its possible. Using basics try with small applications.
After that you can implement advance concepts on these applications with some research and practice.
You can use another programming language like python and many more to build up android and IOS application but you can't build up and default functionality as you can built up and developed by using native programming languages.
I would like suggest that if your are targeting android then you should go for android and if you are targeting IOS then you should go for swift instead of choosing another language.
The reason behind this is that if you spend lots of time to implement something by using another programming language like python ,there is no guarantee whether you will success or not.
if you are choosing native programming language to implement anything it would be easy to implement anything.
Yes it is very possible.
Anyone who understands code can write code Programming languages doesn't matter. Most of us does the same, we know little about our environment and try to come up with a solution but if we are stuck we all search over internet to find the solution. If we can do it so can you.
Just start off by writing some code for your first App and gradually you'll improve with a good pace.
Hope this help, keep coding keep learning!!
Yes, it is possible however researching for codes alone might not be enough to gain a deep understanding about creating apps. It is better if you choose first which mobile platform do you want to pursue (iOS or Android) then start researching about the basics like using its IDE and the app lifecycle. Then create simple mobile apps until you get used to it.
P.S. This is also based from my experience because I also had a hard time learning how to create apps before.

What should i select for my mobile applciation development? Native way or cordova or react,Node.js like things

I want to develop application in android and iOS both.
But i am confuse between native development and development using react and node.js etc.
Please help me to choose (If possible specify reason).
P.S Here cost is not an issue.
If you need high performance and attractive UI and don't want to be blocked by some functionalities that may not br provided by cross platform, I recommend you to use native platform. But if your app doesn't need to be very attractive and doesn't need too much processing, then you can use cross-platform. Actually for many features you need to add plugins if you are building cross platform app and adding number of plugins makes your application slower.
OK, well there isn't much data to go on, but there are several options if you want to write cross platform apps.
There is:
Sencha Touch - HTML and JavaScript
PhoneGap - HTML, JavaScript and CSS
QT - C++ and QML
Appmethod - C++ and Object Pascal
Xamarin - C#
Visual Studio - looks like you can do C# or C++, or Unity for games.
and probably a lot more...
Why would you choose one of these instead of writing in the native language for the platform?
Well, the pros seem to outweigh the cons. If you are targeting several platforms, I would choose one of the options above, simply because you only have to write everything once. If you did it native for each platform, you would write everything twice or maybe three or even four times. Using one of the above tools will be much easier and save you time, and they might be just as seamless and workable as native development.
To simply answer your question, If you would like to be able to write your app once, and be able to manage all future updates by managing only one code base, do cross platform using one of the above tools. The only downside is that you might have to learn a new language (but with a place like Stack Overflow, learning new languages is pretty awesome). It will save you time in the long run.

Portable Mobile/Tablet application proof of concept

I need to develop a portable application mainly for Windows 8.1 and iPad, but could be expanded for Android, WP and iOS later.
The application consists of calling web services to display data in grids and it contains CRUD operation, and it may save some local data for offline mode then synchronizes later when connectivity is up.
I'm torn between too many solutions, I need your advise for better solution.
1- Solution 1: Go Native for each OS (VS for Windows 8.1 [RT and pro] and xCode for iPad): this solution requires code duplication, logic and UI.
2- HTML5 with WebView app: I think this is a weak solution especially that we have local storage, checking for connectivity and calling ws ...
3- Using Xamarin: I think Xamarin does not support WinRT or Windows 8.1 to share logic code between iPad and Windows 8.1
4- Using Xamarin.Forms: Building the UI is tough and also it does not support Windows 8.1.
From your perspective, what is the best solution? please advices if you have any other proof of concept.
Many Thanks.
Most of the html/hibrid frameworks like Cordova (cordova.apache.org), Ionic (http://ionicframework.com/), etc, uses a native WebView on Android. Until Kitkat the performance of WebView is not production-ready and if you've a list with a lot of elements, the scroll experience is really bad.
If you want to do a simple proof of concept, prototype or whatever, I think that html frameworks are a good alternative. But if you are going to put your bussiness on top of one of this framworks, I would not recommend.
There is an alternative to embed a Chrome using Cordova & crosswalk (https://crosswalk-project.org/documentation/cordova.html) but you will end with an APK ~40Mb for a simple hello world.
Just my 2 cents. I don't see a point in using libraries that are unsupported across the platforms you plan to release and support on. Personally, I'd code natively for each platform. While this takes a lot of work, if you have to ask for direction on which path you want to take your application, then this type of project sounds more like a "you reap what you sow" application. Also, you'll be able to directly support each problem without having to wait for patches, but there are 2 sides to that coin as well. Your opportunity cost is missing future features the library will provide, if it's worth it to you.
If you aim at quality, going native is the only way... You can reduce the amount of work like Google is doing: writing the business logic and unit tests in Java, then converting it to ObjC with J2ObjC and to Javascript with GWT.
In your case, being that Java is a dumbed-down version of C#, you can easily find tools to convert to the latter, finding yourself with native business logic for every platform! That should account for 50%-70% of the codebase...
I think going with HTML5 with webapp view is better option.
Using Cordova (Phonegap) most of the native features are easily achievable in HTML webapp.
PhoneGap Platform Guide
Alot of other plugins are available for the advances features like BLE, NFC.
Calling webservice is really not an issue in HTML5.
Simple ajax is enough, however now a days many advanced frameworks are available which makes your work easy. One of the best among them is Angular JS(maintained by Google ).
Angular JS
For database you can access native database of the target OS or SQLite db of the mobile device.
You can check this link
Storage options
So developing a webapp can be a more efficient solution in your case. It can be best way for you as per my view point. However, you can do some R & D and can find the appropriate for you.

Application android Hybrid

I have to develop an android application that use geolocation, and I am confused to choose between web framework mobile and native Android application, and if I must to choose a web frawework which one do you recommend to me?
Actually there are many kinds of framework : like JQuery mobile , Phonegap , titanium , Windev for mobilephones
Regarding the firs part of your question, I'd say this depends on a couple of factors:
1.) Previous experience: Do you already possess experience working with HTML/CSS + JQuery or do you possess experience working with Java? If your answer is yes to the first part: go for web framework development. If your answer is yes to the second part (Java): go for native app development, trust me, it's really easy to pick up if you have already worked with Java before and possess basic knowledge about inheritance and working with packages etc., also, start with the tutorials on developer.android.com If your answer is no to both parts of that question then I'd suggest you go with native app development since picking up Java is relatively easier compared to HTML/CSS+Javascript, in my opinion. If your answer is yes to both parts of the question (i.e you've worked with both Java and HTML/CSS+JS) then look at point 2.
2.) Personal Preference: Clearly, you don't have one right now so just go with what feels easier.
3.) For a geolocation app I'd say native app development is easier, I've been working on a geolocation based app for a while now and I felt that using the Google Maps API was pretty easy and you'll also find significant amounts of help from stackoverflow since everyone and their mothers have tried to make a geolocation-based app. I found the answers to most of my problems here on SO.
If you need more suggestions on this matter don't hesitate from asking!
