My android app has a drop down List,From where user can change language like English, Javanese so on. when user change language then app language will be change. It is a simple app where has only one layout.Please any one help me
I wouldn't trust on-the-fly translation of your strings; even the best automatic translators can produce inaccurate output. Additionally, you add a fair amount of complexity, overhead, and dependency (e.g., having a network connection) by handling translation this way.
The problem of having a "multilangauge app" (as you called it) is well-known, and the process of solving it is called internationalization and localization . In general, when you're working with a framework or programming language, you can look for existing packages/libraries relating to this topic -- it's almost a given that others have spent significant time building a good mechanism(s) to facilitate this.
Android is no exception; it's been developed with localization support built-in. The Android Developer Documentation has a comprehensive guideon Localization that you should take a look at. You'll still need to translate your text somehow, but a lot of the "groundwork" of how you can serve up locale-specific messages to the user has already been laid out for you.
One last note -- the Android docs also provide a tutorial called " Hello, L10n", which walks you through the basics of creating a localized app. Hope this helps!

I have a full-fledged working Flutter app. Now, I want it to support multiple languages, such as Spanish, Hindi, Urdu, etc. (primarily Indian Languages which are available in Google Translate).
I have searched about this, but all of them mention about "arb files" in which I believe, I have to manually write each and every translated string of the whole app.
I would like to build a package with a class (or just a method) which may require 2 parameters, string and the locale in which translation is required.
Kindly suggest me the best way to achieve it and how can I do it. A link to tutorial would be appreciated.
Flutters own step by step walkthrough to i18n is literally the first result that pops up when you put "Flutter localization" into Google.
https://docs.flutter.dev/development/accessibility-and-localization/internationalization
If for some reason you don't want .arb files, you can roll your own. But be prepared that you will find out along the way what is missing and ending up with a home-brewn solution that is worse than Flutters own to achieve the same thing.
There is no magic function to translate text. Even if you could translate on the fly with a translation service, translation services have become really good in recent years, but they (as any human you could hire) are only as good as the context they get. If they get only single words or half sentences, as is common in an app with headlines and buttons, the result will be horrible. As if you just put every single word into a dictionary. That is not translation. It will feel artificial and laughable.
So... give the existing packages a try. Start with Flutters. It might seem complicated, but it's complicated for a reason.
I've been programming for over 20 years, but mostly in the VB and SQL. As a side job, I host game shows at local bars and restaurants (Trivia, name that tune, etc.) and I'd like to develop an android app that I can install on mobile devices to give to customers to interact with the game.
I'm trying to make the game shows more interactive than just pen and paper (and time-consuming, manual scoring). I can get Kindle Fires for $40 each, so I thought it would be cool to create an app that will allow the user to do 3 things:
Choose an answer from a list (Multiple choice), and everyone can answer
Buzz in (blocking other users out)
type in an answer
I'd like the tablets to send the responses to a central "hub" or application that will record the answers so it can automatically do the scoring for me. If possible, I'd prefer to be able to have everything connect through an ad hoc wifi network that I would set up on site (that part I know how to do, too).
I'm not looking to have the questions appear on the phone at this point; I have an office-based application that automates a powerpoint presentation based on questions/answers and other parameters imported from a database/spreadsheet. (VBA is nice and easy for me.)
Ideally, the quiz questions would work like this:
I project the answer where everyone can see it.
After announcing the questions, the tablet apps are "activated" and
the user can then select their A, B, C or D answer (or buzz in, or
type an answer depending the type of questions/quiz).
My hub application would then receive the following information:
team/player name, answer choice, time it took to answer the question
(because I'm thinking of using a points tier that gives faster
players get more points, either based on time ).
The catch is, I don't even know where to begin from an android development standpoint, as I have no experience in that realm. In most programming cases, I know keywords to search on, but I'm totally flying blind here.
Does this seem like a feasibly application? There are systems online that I can buy, but the buzzers are expensive and the software has some significant limitations that prevent me from spending the money. I'd rather develop something myself and spend $40 per client unit and load it up with my software.
(Then, of course, license the whole kit and kaboodle and make a mint and retire in 5 years, living the good life off of my pub quiz empire...)
So, if you have any suggestions on starting points, or specific methods and processes to being fiddling with, an IDE...any help would be greatly appreciated. Once I'm up and running, I will reward you with extra points if you ever come to one of my events.
Go full kotlin !
Android works well with Kotlin and you can have a server quickly setup with : https://start.spring.io/#!language=kotlin
https://kotlinlang.org/docs/tutorials/kotlin-android.html
A good client for Android is provided here :
https://github.com/square/retrofit
You will probably have hard time to get started. Using same language for every part of the system will make things easier.
Also, Kotlin is less verbose than Java and will prevent you to make the usual mistakes found in Java world.
Also, if you create an open source project out of it, you may be eligible for IntelliJ.
Your very first stop is : http://try.kotlinlang.org/#/Examples/Hello,%20world!/Simplest%20version/Simplest%20version.kt
Get to know the language by trying it out. When you are in ease with it, start looking at Anko (https://github.com/Kotlin/anko).
To do the project in an easy way, break it down in milestones.
Simple app which shows 4 buttons (choices) and shows a message for each button. (Eg. you clicked "1")
Small server with spring boot. It should display whatever you post to it. (An "echo" server)
Improvement of the simple app to POST something to the server and display the answer in a dialog.
At that point, you application is practically done! You would have understood enough to complete it. The hardest thing would be behind.
Don't think your are smarter than the flock. Do these milestones, at least. You will be thankful to yourself.
This post may seems unrelated, but I explain how good Kotlin can be in such projects : https://www.linkedin.com/pulse/why-do-android-projects-cost-less-than-ios-christian-baune
I have an application that was build with all the text in English. I would like to add more support for other languages, but am concerned about my users who don't necessarily care about the application now having support for Spanish or whatever new language I have added needing to update. Also, if I am correcting bad translations on a daily basis this would be really annoying to users.
One idea is to make calls to a web service that provides the content for there specific local, which would allow for easy changing if there are bad translations and what have you. The concern with this is of course the speed.
So is there a right way or a better way to add/change values in the localization without forcing people to update?
I understand your problem. And I have one question. Do you think that it will not be annoying for users if your application requests the external service every time when, for instance, new activity is opened?
To my point of view, you should add support of a language, test the correctness of your translation (for instance, you can ask a user from another country who use your application to check the translation) and only then update your app in the market. If all your string resources are in xml files it is not very difficult to support several languages.
So my proposal for you is at first extract all your string resources into strings.xml file (for default language folder), and then just make several values folders with additional language support.
Adding localization is usually (if you followed the good practices) a matter of upgrading a few XML files. So even if the users upgrade, it won't take long at all and they will probably not notice (if they use autoupdate) from the market.
Check this out for more details.
I have an idea to let users translate my application to their own languages.
I imagine this in this way:
If application is not translated to user's system language, English version of UI is displayed and user is asked for help in translation (it's obvious)
Next, user is asked for translate some phrases from English to his mother tongue. And asked to check some others translations. (it's a bit of work, but nothing sophisticated)
Hard part of my idea is:
User presses "update translation" and text resources for this application are update to latest editions.
Of course it's possible to make frequent updates, but this approach has some disadvantages:
1. I have to make all of those updates frequently, and not all of users will be happy with it.
2 Even if updates will be done weekly, time from make effort to get results will be too long form most of users, and probably, response will be not as good as it can be.
Have you any idea how to load translations "on-line"?
Android currently doesn't support this. To accomplish what you want, you'd need to insert your own resource handling code to return strings everywhere they are used in your UI. This means you couldn't let the framework load strings itself (for example no use of android:text="#string/something" in your layouts), and calling your own function to retrieve a string that wraps Resources.getString()/getText().
And you'll also need to deal with the fact that resource IDs are not stable and can change with every build of your app.
So you are looking at something quite non-trivial.
I have done some internationalizations using:
launchpad with android2po
getLocalization
I will first check if they have some kind of api. If there is no API, I would check the gettext's java implementation and handle translations with it.
You could cache any of the current user's translations in a file on the SD/storage, and show it to that specific user. Then, when it gets its weekly update, remove the cached file and start again?
I would like to create a custom open source information management application, that I could adapt to practical needs of a psychiatrist. (and also would really like to avoid inventing the wheel). Could someone advise me what would be a good way to start? I have some amateur programming experience (see below), but I have little experience with java and eclipse (which I have set up with Android SDK plugin on my linux PC).
What I would like to achieve is a simple app where I could relatively easily re-program/rearrange information presenting screens. I would like the major development stages to be something like:
Basic framework of the app is done Main information is added
through the programming environment
basic formatting (bold, color, lists) should be supported
I imagine this would be through HTML/CSS markup Hierarchical (not
too deep) screens with concise information about conditions,
treatments; easy, not too cumbersome navigation is a must.
Possibility to attach own notes from android device
on every piece of information (e.g. on medical condition, on medication,
list of differential diagnoses, etc)
A desktop application that allows for easy adding and editing
of the content
initially could be even sqlite manager or something similar
possibility for adding images,
possibility to add rating scales, which would calculate scores
maybe also possibility to print through some android print driver
* in essence I envision this as a sort of an integrated website with a relatively simple database behind it (sqlite?) running on android. My models would be epocrates and medscape apps, but the content would be more specific to everyday psychiatric practice. It would include aspects of psychological therapies as well.
In about a years time, I think, the content would be interesting enough to see whether the app should go on the market.
My (limited) experience:
I am a MD - a Psychiatrist. I have some amateur development experience (php, html, css, Perl, bash, sed, sql, Access and some time ago - AS/400). I would like to start an app that I could modify as I go - in order to have the most useful info at my fingertips, when I need it in my work. I have considered some databases (e.g. HandDB) but my experience with them is that you get very constricted with their user interface and this hinders fast information retrieval when you need it. Adding information can be clumsy as well.
Why I am asking for help here
Most of tasks above seem pretty standard. I imagine that people with lots of programming experience here, probably would be able to point me towards some information that would help me to get started.
Many thanks for considering this :)
Are you going to develop this app? Everything you mentioned can be easily done by reading the android documentation. Although if its you doing the coding i recommend buying a book
You will find a lot of samples and other support in the android doc
Printing can be also setup using Google Cloud print
If you want to open source your application you can always use google code.
You have asked a really broad question here. But i guess the above information is good to get you started.
