Android Multi language Application

Please See this Image
An android application with 2 languages ENGLISH and ARABIC, there is also a registration activity which includes Password and Email . So when application is in Arabic Language I want to keep password and Email in English language.
Is there any solution for it?
I Just want to make EMAIL and PAssword in ENGLISH if locale is Arabic .

This concept is called Localization. To provide localization support in app, you need to create different values folders in res directory.
What you need to do is, create folder structures with having strings.xml file in each folder.
values
strings.xml
values-ar
strings.xml
In each strings.xml file, declare a string with same key name but put values in languages accordingly.

I hope you have created separate string.xml file for Arabic and English
under valuse-ar create string.xml file add add this lines
<string name="email">EMAIL</string>
<string name="password">PASSWORD</string>
UPDATE
in your layout.xml
<Editext
........
.......
android:digits="abcdefghijklmnopqrstuvwxyz ABCDEFGHIJKLMNOPQRSTUVWXYZ 1234567890"
......
/>
this will allow only numbers and english
letters

Finally found the solution here:
Multilingual Android app: Display English keyboard in Email & Password fields
just add android:imeOptions="flagForceAscii"

try this tutorial

You can use translatable property in strings.xml
<string name="email" translatable="false">Email</string>

What should be the name for values folder for developer english in android

What i want is the name of value folder which consists of String.xml , In that XML i have written key-key pairing i.e "NAME"
"EMPLOYEE_ID". If i use any language key word say en,fi, that will not a good practice. So what should be the name of value folder for above string.xml.
Thank you.

Bydefault for english language it will pickup from values folder and for supporting languages you can refer this link

You should save this xml in the values folder only. Android is not bothered about what the keys are being mapped to; it just makes sure it returns the right value respecting the overrides if any for a particular device's Locale settings.
So, whether the key maps to a value or to some value's key itself, has no bearing on the values folder it should go in; but it should preferably be stored in a different xml file, say, string_keys.xml or something.
values/strings.xml
<string name="employee_name">Name</string>
values/strings_keys.xml
<string name="employee_name_key">employee_name</string>

Change the language of the app according to the default language of the device

I want to change the language of a my application according to the default language of the device in which the app is installed.
For example: if the default language of the device is French, the user will use the app in French.
I've tried to search for a solution, but probably I don't understand how to do that. Anyone can help me? Every help will be gretly appreciated.

To add support for more languages, create additional values directories inside res/ that include a hyphen and the ISO country code at the end of the directory name. For example, values-es/ is the directory containing simple resourcess for the Locales with the language code "es". Android loads the appropriate resources according to the locale settings of the device at run time.
Create the resource subdirectories and string resource files. For example:
MyProject/
res/
values/
strings.xml
values-es/
strings.xml
values-fr/
strings.xml
Where fr = french
And in /values-fr/strings.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="title">Mon Application</string>
<string name="hello_world">Bonjour le monde !</string>
</resources>
Source = Multi language

use qualifiers on your strings i believe fr is for france. So if you have a resource folder called values-fr, then anyone with french on their phone will get the french string file located in that folder and everyone else will get the string file in the values folder (without the -fr qualififer)

You can use qualifiers in all kind of resources of your app. You can for example, have a different layout depending on user language (it's useful on japanese or arabic language).

Best way to store multilanguage values on a database using strings.xml?

this is my first question :)
I'm developing an application that stores animal species in a database. The app must be multilanguage, so I tought to take advantage of using strings.xml resource files.
The idea is to store the english name of the species on the db, for example "cat", "dog" etc.. and then display to the user the actual translation, based on an xml like this (for italian):
<string name="dog">Cane</string>
<string name="cat">Gatto</string>
The problem is that R.string contains the name dog and cat, but they are actually int, so I'm searching a way to use the "dog" string to be used to compare the R.string.dog translated value.
I'm almost sure that my design is terribly wrong, but don't know what the correct way to doing this kind of work, since the app is now in a very early stage of development.
Thank you
EDIT with example
This example illustrates the problem:
Database data:
row1: id="1", value="dog"
row2: id="2", value="cat"
String file strings.xml:
<string name="dog">Dog</string>
<string name="cat">Cat</string>
String file strings-it.xml:
<string name="dog">Cane</string>
<string name="cat">Gatto</string>
My problem is: the user want to insert a specie in his native language (eg. "Cane"), and I want to search in the DB for its existence before inserting.
I should loop for every row on the DB (where values are stored in english), get the the translation of each row (eg: I found cat, then I translate to "Gatto") and compare with the user input.
Is it possible to do that?

If you have a string name you want to use, you can use getIdentifier() to get the string id. As an example, to find R.string.cat:
Resources res = getResources();
int stringId = res.getIdentifier("cat", "string", packageName);
In the above example, if there is no R.string.cat found, it will simply return 0. It's an easy test to see if a string exists.
Alternatively, you can get an array of all the string ids in your R.java by using something like:
Field[] fields = R.string.class.getFields();
int[] ids = new int[fields.length];
for(int i=0;i<field.length;i++)
ids[i] = field[i].getInt(null);
Of course, that will also look for any strings that you don't really intend as translations, such as dialog/window titles, label/button captions, etc. I wouldn't advise it in the general case. If I had to do it, I'd prefix the "translation" strings with something so I could easily tell what is what, something like "entry_cat".
Note that we're using reflection, and if you have a lot of strings, it could slow you down. If you are going to loop through R.java, I'd advise only doing it on start-up, and saving the values in some sort of array/list.

First read this.
http://developer.android.com/training/basics/supporting-devices/languages.html
You can create value folder with many language's i.e janapee,dutch etc
you can find out value folder inside the res folder in your project. and create new value folders.
res/
values/
strings.xml
values-es/
strings.xml
values-fr/
strings.xml
JUST TRANSLATE YOUR WORDS BY GOOGLE TRANSLATOR IN ANY LANGUAGE AND PUT INSIDE THE STRING.XML FILE .

Well, first of all, start reading this here:
Suppose that your application's default language is English. Suppose
also that you want to localize all the text in your application to
French, and most of the text in your application (everything except
the application's title) to Japanese. In this case, you could create
three alternative strings.xml files, each stored in a locale-specific
resource directory:
res/values/strings.xml Contains English text for all the strings that
the application uses, including text for a string named title.
res/values-fr/strings.xml Contain French text for all the strings,
including title. res/values-ja/strings.xml Contain Japanese text for
all the strings except title. If your Java code refers to
R.string.title, here is what will happen at runtime:
If the device is set to any language other than French, Android will
load title from the res/values/strings.xml file. If the device is set
to French, Android will load title from the res/values-fr/strings.xml
file. Notice that if the device is set to Japanese, Android will look
for title in the res/values-ja/strings.xml file. But because no such
string is included in that file, Android will fall back to the
default, and will load title in English from the
res/values/strings.xml file.

Which strings to store in strings.xml?

Are there any suggestions on which strings you should store in strings.xml and which strings can be stored as String objects? For example, do I have to put a string into strings.xml, if I use it only to complete a certain action and then it can be destroyed? And what is the main reason in storing strings in xml? Thanks in advance for your answers.

Any string that will be displayed to the user should be in strings.xml. This is useful in case you ever want to support other languages for your application. If you do, you just create a new strings.xml file that language with translated values. You can learn more about it here.

One reason is multi-language support.
You should store the strings that you use in Activities - TextView, button's caption and so on.

You should put most constants in strings.xml, your app title, button names, textview contents...mostly things that wont change in your application.
Another reason for storing strings in xml is for localization. You can store different files for each different Locale or language, and Android will grab the correct file for the phone's selected Locale or language.
Here is a link to the String resource Android page, it will go more deeply into how the language support is done.

You don't store all the strings in strings.xml, but only strings constants related to user interface, the strings that you want to translate in different languages.
You can have different folder like :
values
values-fr
values-de
in each a strings.xml file with you UI messages translated in many languages.
