First I am a java backend developer and are looking for clues in the right direction
Question is it possibly to create a app what third party developers could include in their app with minimum of effort .
Background: I have a numbers of potential customer what all have a existing app made from difference developers some in house others from extern developers
Now I want to offer the customer a extended feature of where app, and to avoid what the customers need a whole rewrite and cost of their app , is it some how possible what I could code a app what could be included in the existing app with a with a minimum of effort for the customer (its alright what i have to make a change to every different app)
and a side note can I somehow protect my part from being copy from whose who have to include the app/sdk
Any clue on technical papers are very appreciated
You can use
As you are good with java I suggest you to look into Xamarin as C# and Java are very similar
Or if You are Good with HTML and know a little bit of Native then you can Go for PhoneGap Cordova
Or if You are Good with Angular Js you can Go for IONIC framework, cool part is you can drag and drop to build UI
All this frameworks allow developers to write code for all plateform with minimum effort.
I searched many documents but didn't find any exact solution for my problem. I want to implement audio call and screen sharing in Android native application using webrtc without using any third party sdk.
I found one demo example i.e apprtc but it supports only audio call. How to implement screen sharing too?
This answer may be irrelevant for the OP, since the question is very old.
Anyway, for anyone in the future searching for something similar, check this commit in webrtc repo. It adds a screen capturer for Android.
I am developing a mobile app targeting the iOS and Android platforms. The app will consist of:
A relatively simple 'user login/signup and listing of database items' type of interface, powered by an already built webservice from and existing web application.
A video capture and upload feature using native plugins.
I have done extensive research on PhoneGap for the last week, and have determined that even considering the well documented issues and limitations of PhoneGap, it is well suited for the 1st part of my app.
However, given the limitations of the PhoneGap Capture API ( org.apache.cordova.media-capture ), it is not appropriate for capturing video for upload, mostly due to the lack of control over video specs. (On most devices, video captures will be enormous HD files that are not suitable for upload, even on Wifi, and certainly not over 3g/4g.)
Given my resources and timeline, I've determined that building native apps in both Java and ObjC are impractical, at least for now. I have very little ObjC and Java experience, but I am fairly confident and eager to learn these languages if need be.
That said, I am considering 2 options:
The first, and probably most rational, is that I pick the platform with the greater market share of my existing user base (iOS), suck it up, and go native.
The second, and perhaps lofty option, is that I develop a hybrid app in PhoneGap, targeting both platforms, and circumvent the limitations of my video capture ability by building native plugins for Java and ObjC using PhoneGap's plugin API, thus reducing development time on the rest of the app, and using native code only where it's needed.
The requirements of my video capture plugin would be as follows:
Have complete control over the specs of the recorded video, most importantly resolution and bitrate. (Presumably with AVFoundation, and the like in Adroid SDK).
Control the user interface of the video capture functionality.
Obviously, I am aware that these tasks are very possible on both platforms when developing in the native api's as is evident by existing apps in the market. (Vine, etc..).
My real question, is what are the limitations, and issues with extending native functionality via PhoneGap's Plugin API? There are almost no examples of work done in PhoneGap with this level of native implementation of video capture. The one example I've found is this plugin, VideoCapturePlus, which although I haven't been able to get to work, seems promising.
I am especially interested to find out if anyone out there has successfully implemented native plugins in PhoneGap with this level of complexity, or if it is a rabbit hole I will wish I hadn't gone down.
I have essentially gotten to the bottom of this question, that I am sure others are and will face. I will address the topic in 3 parts:
Can I do [something] in PhoneGap (as opposed to in native iOS or Android SDK)?
This is a question I'd imagine many developers considering the PhoneGap framework find themselves asking, as did I. The short answer is YES, YOU PROBABLY CAN.
How do I do [something] in PhoneGap?
Plugins! Here's the rub: Cordova (PhoneGap) in all it's brilliance is extremely limited in the way it accesses native hardware features, especially when you get into video/photo/audio capture.
This is where plugins come in. There are thousands of PhoneGap plugins at this point. Many are as simple as 4 lines of Java and Objective C to get over some simple thing that PhoneGap just won't do. Others are large projects with lifecycles of their own.
In my case, it became very clear very early on that I was not going to be able to build my app with the video capture functions that existed in PhoneGap. That said, I went shopping for plugins. By the end of my project it had taken 2 plugins that extended video functionality and four more to do other small various things I needed. In a few cases, the plugins I found did not have everything I needed, and I wound up contributing bits of code. If the projects are active on GitHub, I highly recommend this.
In the end, there were things I wanted to do that I could not find plugins for. I still have plans to build some of my own, but am not there yet. Bottom line: Outside of gaming and other 3d rendering applications, you'll be hard pressed to find something that can't be achieved with a PhoneGap plugin.
For those interested specifically in video capture, these are the 2 plugins that got me over the hump in my project:
VideoCapturePlus
Video Screenshot
Should I build my app that does [something] in PhoneGap?
Of course, this question is up to each developer, and what the goals of the app are. In my case, a simple app that among other things captures and uploads photos and short videos was quite possible. There are certainly cases in which the parameters and goals of the app make it such that native development is the best option.
That said, for most solo devs or small teams with limited resources and little or no Java or ObjC experience, the answer to the question, "Should I consider PhoneGap?", would be [in my best Jim Halpert voice], "Absolutely you should". As an added bonus, I will say this: In my case, the HTML5 layouts, and much of the front end JS that were used for both the Android and iOS versions of my app are largely reusable for the mobile web version of my app. Being able to maintain a single codebase for those three things offers efficiency that even larger resourced organizations shouldn't overlook.
I'm planning on writing a multiplayer game with Android as my primary focus as far as OS/platform, but I would like the ability to port the game to at least the web. I'm looking into Andengine as I'm just starting out with java and android and it seems the most noob friendly. The game shouldn't be too demanding as it will be a 2d turn based game with simple animations and chat.
So my main question - is it possible to port a Andengine game to the web?
If not what would you suggest?
I looked at libgdx, but I'm concerned that it might be a little to advanced for someone just starting out with java/android. Am I correct in my assumption?
Another idea I've been playing around with is writing the game in Flash and porting it to Android with Adobe Air - does anyone have any experience with this? Is it a bad idea? I kind of have my doubts of how well this will work, but if nobody can really talk me down from this idea, I might just go this route.
I've also considered writing the game in pygame as it seems easier but I don't like the idea of players having to download something like Pygame Subset for Android or Kivy to run the game. So basically if the other options are either too difficult or wont work on android then I'm probably just going to go with Andengine and consider rewriting it later for the web if people like it enough.
Moai SDK is an open source multi-platform framework for game developers.
One codes in lua - a dynamic programming language (that is easy to learn).
Apps made using Moai can be deployed to iOS, android and the chrome web store.
Moai could be an alternative.
Andengine makes a fine starting place. (I have made 3 projects with it now and I really like it). but it does not deploy to anything other than android. That is its strength and its weakness. As a strength, it is very easy to integrate android OS features and libraries with your project and has good performance. And as a weakness, well, it only runs on android.
Code-once publish anywhere platforms trade off development time for speed and size usually.
Some top competitors in that area are:
Ancsa Corona
AppMobi
PhoneGap
Unity3D
Adobe Flash(bonus of web distribution)
and others. (Moai SDK listed by #andrew, for example)
Each platform has had successful games launched with them. Find the one that suits you and your projects needs best. Do not forget to check for things you will want to integrate, such as using Facebook for mobile, or AdMob, or OpenFeint or other 3rd party services.
Good luck and enjoy you game making!
Just a side note, user do not need to download "Kivy" to run the game. As other toolkit, your application will provide Kivy as other libraries you'll use.
I tried to give the main idea in the title as good as i could. I am a good programmer in Java and i studied the android sdk. I posted my question here because i believe you can guide me.
Two companies need to send text messages(not sms) in the same android app. The number of users of this app is not known but it could be 500 to 200k. Can Gwt and app engine help me to make it possible. To make it clear i didn't studied these services, but i know if i use them it will have no cost.
The other solution is to make my own server and a web app with another language.
Your answers will save me time.
Thanks in advance.
GWT and App Engine are front end and backend platforms which can be used to build use cases which fit a different need.
App Engine provides a PAAS stack with limitations of hardened sandbox, GWT takes the pain out of Javascript programming but restricts the customization.
If you are using http to communicate with servers then GAE should do the job
