I want to use pygtk app for android app development. I want to use app like pygtk which will have easy drag and drop options for developing the front end for android application.
Is there any of such thing which can let me design my front end for android app with drag and drop? (specially in python or else in java)
I see you tagged the question with kivy, I can only answer that we don't have such a thing for kivy yet, although a GSOC student got accepted for this and will start working on it soon, let's hope it'll work out nicely :). I'm of the opinion that the kvlang we have in kivy makes the need of a Graphical Designer far less than in other toolkits, but i guess YMMMV.
Other than that, I don't think you can do PyGTK development on Android currently, but I think PySide works, so maybe QtDesigner or some other Qt design application would be worth a look?

I'm working on a project whereby we're creating an app for people to call/message one another.
We're currently developing in Androidstudio, java, but even after we've launched the app, it seems that most of our interested users are on iOS instead.
Is it possible for us to convert Java > Kotlin and use Kotlin Native for our iOS app? I mean, if it's possible we'd like to use a way that wouldn't need us to use too much Swift, since we're a bunch of undergrads who's doing this on interest and we haven't developed in Swift before.
Seems like there are certain projects that are multi-platform so far, but I'm kinda really skeptical about the possibility of us doing so, even though most of our code are written in web.
I'm sorry I'm not that well versed in programming or if this question has been asked before, I'm still kinda new to programming and everything.
I'll really appreciate it if you'd so kindly answer this question! :)
You can use Kotlin/Native for your iOS app and not write any Swift, but you still need to change all of your UI code so that it uses the iOS UI framework and not the Android framework. This conversion needs to be done manually; there's no automated tool for that.
You could try out Flutter if you want to have one code base for both Android and iOS?
I created an Android app which communicates via USART with a µC in order to evaluate data. My co-workers and customers should use the tablet for only this purpose now. Is there any possibility to "hide" the Android OS or making it inaccessible?
Devices are rooted and I am willing to build custom ROMs (even though I do not have any experience with that yet). Are there any approaches available that I do not have to start from scratch?
Many thanks for your help.
Well. That what I'm trying to do !
The first thing I tried was to start the app just after the boot of the device (Quite easy with this).
Then, I get Android source code, and I hide the bottom bar using this code
The problem is, if your application is not stable ... you'll have some problem.
If you want to modify Android source code, the developper doc contains a very good tutorial to start !
I have a great idea for an Android app, but as I'm only familiar with php/js, I'm uncertain of which approach I should choose for creating it. The app will be based on a google map with a lot of position markers. There won't be any fancy animations or other heavy resource-demanding activities.
As I see it there are three different options:
Read up on Java and program the whole thing in Java
Create the map activity in Java as a mapview and then use webviews for the other activities (which can easily be scripted as html5 webpages.)
Script everything as a webapp (not really an option, as this is not a real mobile app imho.
I'm most keen on using no. 2 as I'm quite familiar with html/php/js/mysql. Have to read up on the html5 specifics, though. Questions:
I need access to GPS and camera hardware. Is that acheivable in webviews?
How complicated is it to pass variables between js in webview activities and java in other activities?
How big a difference in performance can I expect if I use option 1 vs option 2?
Other thoughts?
Kind regards,
Anders
You can choose number 2, but as we are talking about an android phone, you might want to get really accurate coordinates for your map, and you can only achieve this by accessing your phone GPS, through webviews the best you can get is the location trought the device internet IP adress, wich doesnt lead to a very accurate geo position.
The best choice is a 100% java application in my opinion.
1) Yes it's possible, but as commented it will be less accurate and probably slow.
2) Not complicated. Painful if you need loads of interaction between a webview and native app. Using a Javascript Interface that can be set up from the native app. You can basically inject javascript in a webview's html.
3) Heterogeneity of performance depending on device. Because your implementation will be based on the device's browser you can expect to get really sluggish behavior for older devices. Anything to do with HTML events (Dragging, Tabbing...) will have a knock on most devices, from my experience.
4) As #vodich comments there are other party frameworks. My benchmarking on PhoneGap and other js-based options is that they're a waste of time if you are looking at developing a professional app. I haven't developed on Adobe AIR but find a pain the need to be installing plugins to get native functionality (access to sensors, camera, etc) Mobile is all about fast, responsive behaviour. HDI is your finger, user is fast, so app needs to be fast.
EDIT: So hell yeah! Java FTW!

4.Other toughts?
Yes, if you really want to make a great Android app, you should be using only Android and specific Android UI components, and give it a native look and feel. And regarding 1,2 yes it is possible, I would say not so complicated to just integrate them, but I think you'll eventually get in big problems.
Learn Java and write your application natively.
Webviews might allow you to use your php skills to present something to the user, but it's entirely one-way - you'll not be able to interact with what's inside.
The Android developer site offers fantastic documentation and jumping from PHP to Java isn't greatly difficult, though you'll need to get used to strict typing and "real" OOP.
Other thoughts? Don't go down the PhoneGap/Cross platform toolkit road - it might allow you to write applications for multiple platforms and using your current skills, but in the end you get a subpar app that doesn't feel right on either platform and doesn't fair well as future versions of iOS and Android are released.
I have to play flash (swf) in my program when the user clicks on a link. Which is best? Concentrate on android 2.2 and use the Adobe Flash Player, or what do you recommend? I have tested WebView, but can not play swf in the emulator. HTC has a custom flash player but it feel like a limitation.
Some code samples to play swf in android that works for as many users as possible?
Have you considered using Flash to create an AIR app for Android rather than using Java? If you have to download and run external swf files, this seems like a path of least resistance to me. Of course, this requires learning ActionScript, but it's not difficult if you know Java.
It's hard for me to give you a solid recommendation, much like toggy-tog-togs answer. B/c we don't know exactly how many swfs or what kind of swfs you are playing.
I mean, if your application is pretty much just playing swf's and you need a UI to run it, it might be worth looking at Air and Flex.
However, to address that first problem you had. I haven't tested it myself, but I am nearly 100% certain, that your emulator won't play flash content in a webview b/c you don't have flash player installed on the emulators. :-) Android supports Flash content but only after you download and install the player from the App store.
So you might want to try running your emulator and installing the Flash player app. I don't even know if that is possible but you ought to try it out. :-)
By the way, the Android emulator is trash, if you are serious about developing for the Android platform, you really have to pick up a device or two to debug on.
Good luck!
So your using JAVA if you are then it is best to open up the browser that is the easiest but if you are wanting to use it in the application (This is less loading time if it is included in the package) but it costs try using JFlashPlayer (It Costs For the full version) http://www.jpackages.com/jflashplayer/download/ This runs very fast on the android platform. Hope I could help.
I have a general old-fashioned phone that has no special app system and uses Java (I assume ME) for the few applications you can use on it.
This is still a decent userbase and I'd like to start programming for this type of phone. I already know basic Java theory and syntax, so.. where do I get started for programming for non-smartphones?
Best programming environment for Java ME IMO is Eclipse with EclipseME. Includes lots of built-in stuff about packaging your midlets etc. The SonyEricsson wireless toolkit is great for PC-based testing and debugging, but don't forget on-device testing!
If you don't know much about Java ME's lifecycle, then get reading as widely as you can, and try lots and lots of examples. Start with the JSR-118 (MIDP2) javadocs; you'll want these open on your desktop at all times while coding.
Don't waste too much time with the form-based user-interface; I recommend either rolling your own using Canvas, or read about LWUIT.
You can do all sorts in Java ME and target a very broad range of handsets. HTTP capability is guaranteed, so you can hook up to a public web service, or create your own using something like Google Appengine.
Finally, you can release your app very easily on somewhere like Get Jar. Don't be put off by those who say "no owners of Java ME handsets want apps", you'll find the most popular user bases on this site will be users in countries such as India and Indonesia.
Good luck!
I would start with a book on J2ME and work from there.
Try Beginning J2ME: From Novice to Professional.
You could also download the J2ME SDK and play around with the example they give.
For tutorials have a look at the stackoverflow question https://stackoverflow.com/questions/584923/do-you-know-a-good-j2me-tutorial as mention in my comment.
I started with writing simple Flashlight application (choose how much seconds screen will remain lit) in NetBeans ME. And other app which I mange was Countdown with some graphics and sound. After that I found limitations too much annoying and now I'm waiting for my Android phone.
in short:
If you want to try it out - you don't need to buy books. There are plenty of tutorials around.
But, if you want to start deep development - don't waste time.
