I had been working on android since a little long. Now I am wondering about titanium. Is it possible to write android (java) code in titanium app since the app is build in titanium? If yes then how? Actually I am having problem dealing with push notification for android in titanium. So I got a solution to build complete app in titanium and then if possible use android code in app to deal with push notification. How? Please do response as quickly as possible. Thanks in advance.
To answer your question directly, you will need to develop a native Android extension to call Java code via JavaScript in a Titanium application.

You should be checking out the docs Here tells you all you need to know
Hope it helps

yes it is possible but remember that the titanium tools lag behind the official android ones. Documentation is poor and often wrong, code is laggy and the resulting .apk are much bigger.
Why are you thinking of using Titanium? For cross-compatibility?
If you are thinking about that you have multiple possible ways:
1) Build a minimum common denominator, like titanium, but better: Write a core application for both android and iPhone so that it will be fast and light on memory, with a modified broswer to show your content. This way the interfaces will be much easier and you'll have to write the content just once.
Still you will be able to access low level hardware, like GPS, compass, gyroscope.... easily without consuming too much battery (unlike with titanium) as needed.
2) Find an existing minimum common denominator: Javascript work both on iPhone and Android.
3) There are many other options (Adobe air, python, custom scripting, mobile web site, ...) but I think that the cons outweigh greatly the pros.

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.
I have a few questions about webRTC on android. I can say I'm new about android and webRTC but I can also say I made tooo much research about webRTC on android. But still have a few questions. (some of them because of I'm new, and some of them because of I'm okey but not fully)
I'm trying to make an android app which is going to communicate between web browser (first choice is chrome) and android device directly (p2p we can say). So I made too much research and I found webRTC is good for me. Do you advise me something other or is it okey you think? (also I am going to code a plugin for chrome).
Nearly every document says 'android is not directly support webRTC'. So I need something to provide me webRTC on android. What it is? Is it native android that I have to code? Is it native (NDK) library that I have to include my project? Or is it a java lib? Or should I go for cordova/crosswalk or sth like that? I researched all but didn't find something can help me. Yeah there are documents about it but not enough..
Some of documents says, I need chromium. But why and how? They show me lots of linux terminal commands and even there is no a line java or C or C++ code. Even some terminal commands and links that they give is not working.
I read/found/tried these things as a result of my research:
Apache cordova
Crosswalk
http://www.webrtc.org/
https://github.com/webrtc
http://webrtc.github.io/samples/
http://simonguest.com/2013/08/06/bui...t-for-android/

https://github.com/pchab/ProjectRTC

and something more..
in a nutshell I need help. Please give me your hand. Thank you. (because I'm really very helpless and tried to do my best)
Thank you.
As others have suggested, I recommend checking out g.co/webrtc. As I understand it, your goal is to make Android connect to a web browser using WebRTC. There are two (three) ways you can achieve that.
You can just use Chrome, Opera or Firefox for Android. All these browsers support WebRTC, and it allows you to use the same code for your web app, as for your Android app. With the new Add to homescreen support, as well as support for push notifications from web apps on Android, this could be a very good solution for you.
You can use the Android native WebRTC library, available from WebRTC.org. As mentioned in my article, I recommend using the pristine.io compiled library, available from MavenCentral.
If you can limit your application to Lollipop, you can use WebView, which support WebRTC now iirc. I don't know much about it though.
And the best resource for getting help is discuss-webrtc. It's a lot more active than StackOverflow.
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.
Anyone know if its possible to develop android apps with PowerBuilder.
Haven't found much regarding this on Google, which might mean that it isn't, but still want to hear the opinion of ppl at stackoverflow.
thanks in advance
right now I think the only possibility is Appeon Mobile for PowerBuilder. This is a beta version and it is supporting iOS right now, but in several months it will be capable for building native android and Windows Phone app too.
http://www.appeon.com/list.do?fid-60-page-1.htm
I hardly waiting it also :)

One other possible solution I've considered but it is NOT a trivial solution. Look at IIS modules and handlers in the MSDN. Basically you can write a handler in PB.NET that will be used in IIS to create HTML5 that will run in just about any browser including mobile.
You then could assign a certain file type (e.g .powerbuilder ) which will be processed by your custom handler that was written in PB.NET.
Might be a good open source project.
Does anybody have experiences from cross platform mobile app development framework MoSync?
It sounds very good and promises much. But does it deliver?
We have used MoSync for 8 months now and I have a good feeling about it. It is still magic to me that you code in C++ and out comes a jar-file or whatever platform you choose.
It is great for application development but I wouldn't recommend it for gaming with advanced graphics. It seems too slow for that on Symbian.
The APIs are very easy and I learned it very fast. And I have the freedom to do whatever components I want thanks to the MAUI framework and using widgets with skins. You can really make an application look very nice.
It is great for me as a developer that I can support so many phones and platforms. I can also do specific behavior and include/exclude functionality based on the phones capabilities.
When it comes to deployment I end up with hundreds of binaries for every device and I have to take care of them my self. To put them on a web server somewhere and make sure that every user get the correct binary when they try to download the app. I wished that they had some kind of app-store so they could host the apps.
MoSync still have a bit to go until it is working properly. There is no guaranty that an application that is build for a specific device actually works on that device. But I'm sure that they will reach there very soon. And when they do... I simply just need to rebuild my app with the SDK (I think).
Have you seen Mosync 2.6, I think this solves most of the problems you mentioned,
the feature list is at:
http://www.mosync.com/documentation/manualpages/whats-new-mosync-26-pyramid
I personally I'm quite excited about the whole HTML 5 integration, it sort of blurs the line between native and web app.
Hope this Helps
