I have some problem when I trying to follow a tutorial to create a localization app: After I created all the folders and place the flag images, I run the app and expect to see the greeting message and corresponding flag for the locales; here is the problem:
The flag should change to Germany flag. (I set England flag as default)
This is the error message when I click the flag(Yes, the flag is a button.)
This is my res folder structure:
This is my res directory:
Textview is working fine, only problem is the flag image won't change with the location. Can somebody show me where the problem is?
You have to mention DPI into the name of your drawable folder after language code. For Ex, drawable-de-rDE-hdpi. Otherwise it will not find resources.

I am trying to display a png image in android studio. When I put it into the image view, it will display in the design view but when I try to run the app it gives me the two following errors.
Error: Invalid file name: must contain only lowercase letters and digits ([a-z0-9_.])
Execution failed for task ':app:mergeDebugRescources'.
Now I know this means it cannot have upper case letters in the file name but there has got to be a way around this right? My file name is the following:
C:\Users\Derek\AndroidStudioProjects\CheckItOut\app\src\main\res\drawable\logo2.PNG
I think the error is the fact that the PNG is in all caps, I don't know why it does this. Any help would be greatly appreciated, in case you couldn't tell; I am very knew to this stuff.
You need to rename logo2.PNG to logo2.png uppercase letters are not allowed for image resource files
About this i can only say that when calling a drawable in android you should use only the name, without extension (in your case only logo2):
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.logo2);
//using R.drawable.logo2.png will get you an error
If this is not working, maybe using .PNG may be the problem, try changing the resource
I keep getting an error when creating folders for internationalization. But the errors appear just for folders with the name like values-xx_XX. If I have values-xx everything is ok, but like I asked in the title I want to make 2 separate folders for the (aprox.)the same language: values-pt_PT,values-pt_BR. How can I do that without getting any errors? Note: The error is not specified anywhere, the eclipse is just marking the folder with a red cross and doesn't allow me to run the project.
Every hint is appreciated. Thank you! :)
Use the format values-xx-rXX instead of values-xx_XX. In this instance you should use values-pt-rPT and values-pt-rBR.
See http://developer.android.com/guide/topics/resources/providing-resources.html#AlternativeResources
The language is defined by a two-letter ISO 639-1 language code,
optionally followed by a two letter ISO 3166-1-alpha-2 region code
(preceded by lowercase "r").
I haven't done it myself, but after a quick search here, I found Setting region based Local in android where they suggest using the constructor as you did:
Locale locale = new Locale("ar","SA"); //(language,country)
But also, if you wish to pass it as one parameter, you'd still leverage the lowercase "r" as in the "values" folder, like this:
Locale locale = new Locale("ar-rSA");
Hope it helps :)
My country (Spain) has several languages (es-ES, ca-ES, gl-ES, eu-ES). We won't add all the languages for now so we would like to use main language in Spain, i.e. Spanish (es). We would like to display the /values-es/strings.xml when the user has selected one of the other languages in the country. How can we do that?
Oh, and we would like to use English as the default language (/values/strings.xml).
It would be great to have something like /values-ES/strings.xml, but I suppose that can't be done because the first code should be the language code.
Now we are copying the /values-es/strings.xml file to the other folders (values-ca, values-gl and values-eu) but we'd like to avoid that.
I think that you should have only 2 folders with 1 strings.xml for each other:
res/values/strings.xml this resource will contains your text in English ;
res/values-es/strings.xml this resource will contains your text in Spanish .
When your app is installed on a device which is configured with the Italian language, it will use the file resource on case 1.
When your app is installed on a device which is configured with a Spanish language (and there are a lot of Spanish language out there, think about South America countries), it will use the file resource on case 2.
You can do it easily with Android Studio:
right-click on res folder
go to New > Android resource directory
a window will show you some options; pick Locale and then click on the button with those symbols "> >"
then on the Language list, pick es: Spanish and then click OK, as showed in the image below (note that by default the Specific Region Only has Any Region selected!)
By experience: I never faced up a Breton, Corsican or Provençal users claiming for a full translation of the application in their language (by default the app has English as default and French).
I would say you want to do something like this.
if (Locale.getDefault().getISO3Country().equals("ESP"))
{
Locale[] locales = Locale.getAvailableLocales();
for (Locale loc : locales)
if (loc.getISO3Language().equals("SPA"))
{
Locale.setDefault(loc);
break;
}
}
Note: I'm not sure if I got the ISO3 language and country codes right. And you'll also have to do something for the (rare?) situation that the es-ES locale is not available.
If you are trying to override Catalan with Spanish, you should probably have that in the values-ca/strings.xml file.
The way to do what you are asking is to provide the resources in the appropriate mobile country code resource folder, which takes precedence over language-region resources.
Assume that you have the following situation:
The application code calls for R.string.text_a
Two relevant resource files are available:
res/values-mcc404/strings.xml, which includes text_a in the application's default language, in this case English.
res/values-hi/strings.xml, which includes text_a in Hindi.
The application is running on a device that has the following configuration:
The SIM card is connected to a mobile network in India (MCC 404).
The language is set to Hindi (hi).
Android will load text_a from res/values-mcc404/strings.xml (in English), even if the device is configured for Hindi. That is because in the resource-selection process, Android will prefer an MCC match over a language match.
The MCC for Spain is 214.
(See Localization)
I found another tricky solution: hard links. Although it doesn't remove whole problem completely, at least it protects you from routine task of copying file across multiple directories or making equal changes in all existed files with risk of miss something.
But I must admit that there is some caveats:
1) Some IDE does not support working with hard links by-default. Intellij IDEA and Android Studio will break your hard links if you don't disable "safe write" option in settings.
2) Most version control systems also doesn't support hard links by default. Let's take git for example. It will break existing hard links after reverting or merging changes.
Currently, I'm using batch file for restoring hard links after they get broken by git.
In a general term, there should be only one strings.xml file under values folder containing the relevant data.
If we explicitly specify different values folder like values-ca,values-es, whenever there are setting changes in the android device, it will look to the particular folder and take the appropriate strings value.
If the requirement is keep uniform text means better have only values->strings.xml file alone with the required data.
But with this approach multilingual apk is not possible i.e. for other country different language is expected, there will be variations again. So wherever we need uniform language, lets go with single folder alone and wherever multilingual is preferred, we can have multiple values-es,values-ca folder like that.
Hope that helps
How about trying to set it in java, instead of using strings.xml.
As doing it programatically gives you more flexibility at run-time.
Configuration config = new Configuration(getResources().getConfiguration());
Locale locale = Locale.getDefault();
String country = locale.getCountry();
String language = locale.getLanguage();
if (country.equalsIgnoreCase("ES") && (language.equalsIgnoreCase("ca") || language.equalsIgnoreCase("gl") || language.equalsIgnoreCase("eu"))) {
locale = new Locale("es");
}
config.setLocale(locale);
And then you can simply have one /values-es/strings.xml for all the ES country languages.
I have the next problem:
When I add a new folder called "values-en" and I move the strings.xml file from the default folder "values" to that "values-en", I always get the next error:
Couldn't resolve resource #string/my_string
I have cleaned the project and refresh and the warning is always there.
Is there any restriction where I must always have a strings.xml in the device folder "values"?
Someone has experimented the same?
Thanks in advance
You must have the values folder. To support multiple languages you can add the other values folders (values-en, values-fr, etc).
In the default values folder you declare your strings in your app's default language and in values-en the same strings but with their english translation.
I'm new to Android. When I add a button/views in Graphical layout it adds the label text this way- android:text="Button" . Why doesnt it add "android:text="#string/my_label" and add a string resource in string.xml file. Can't it be done automatically in eclipse?
I have searched a lot but I have not get any automated way to add a string to the resource file But This will save your time a lot IMHO.
Select a String, click Refactor --> Android --> Extract Android String.
Thanks to Brent Hronik. CTRL-1 on Windows works fine.
Because you don't have to use the #string resource. The purpose of the #strings resource is to make it easier to change elements about your code. For example, if you are using your application title in mutliple places, let's say in every dialog box, then if you change the title you would have to change it in all the instances that the app title is being display. So in this instance the #string/App_Title could be set to "My Program" and all of the dialog boxes can reference that. If you change the title to "Hello World" then all of these are changed. The #strings resource, while eclipse tries, doesn't have to be used for every string. Not using it is the equivalent to hard coding the value. There are plenty of reasons for and against using #string for everything.
I am not sure if there is a setting in eclipse that will automatically add a string to the resource file when the control is added.
(EDIT: Based on other users CTRL+1 is the short cut to do this.)
You can add the string to the strings.xml by clicking command and 1(on a mac, assume it would be control 1 on a Windows or Linux box) simultaneously. This will add the resource to strings.xml and then open that up in the editor.
Thanks Siddiq Abu Bakkar! I didn't think it would be there.
On Eclipse (and Windows) the shortcut is:
Alt+Shift+A (release all and then press) S
When you use Eclipse for first time it's not easy understand how to use these kind of "complex" shortcuts.
I can't vote and i can't comment answers yet (missing reputation as i'm a new user)
But i confirm :
1) hard type the string in your code like
mydlg.setTitle("hello guys");
2) select your string (e.g : "hello guys")
3) press Alt + Shift + A then press S
a dialog will appear to let you add a new string into resources. Everything should be already filled into that dialog box.
