If the language is english then use an another link than if it's german

how does the if condition look like?
if(Locale.getDefault().equals("English")){
Log.i("Language","Englisch");
} else if(Locale.getDefault().equals("Deutsch")){
Log.i("Language","Deutsch");
}
This won't work

Locale.getDefault() will return a static Locale Object, not a String. So calling Locale.getDefault().equals("English") will not work.
Try this:
String language = Locale.getDefault().getLanguage();
if (language.equals("en"))
{
// Use English link
}
else if (language.equals("de"))
{
// Use German link
}
public String getLanguage ()
Added in API level 1
Returns the language code for this Locale or the
empty string if no language was set.
Or:
String language = Locale.getDefault().getDisplayLanguage();
if (language.equals("English"))
{
// Use English link
}
else if (...) { ....
public final String getDisplayLanguage ()
Added in API level 1 Equivalent to
getDisplayLanguage(Locale.getDefault()).
Here are other possibilities:
Locale.getDefault().getLanguage() ---> en
Locale.getDefault().getISO3Language() ---> eng
Locale.getDefault().getCountry() ---> US
Locale.getDefault().getISO3Country() ---> USA
Locale.getDefault().getDisplayCountry() ---> United States
Locale.getDefault().getDisplayName() ---> English (United States)
Locale.getDefault().toString() ---> en_US
Locale.getDefault().getDisplayLanguage()---> English
Documentation here.

Locale.getDefault returns a Locale, not a String. If you want to know more about that locale you call getLanguage and getCountry on the Locale. Look up ISO code for language and country.
Usually, in android you solve something like this by different resources. Under res/values-en/ and res/values-de/ you can define language specific strings.

Android detect string/user input language

can I determine which language the user enter to editText ?
example :
if the user enter "поэзия song" witch contain from english and russian letter the methood return english, russian.
i dont care if the methood detect the language in the keybourd and return english, russian just becuase the user use in english and russian keybourds.
i prefere the second option becuase there is aproblam to determaine the language if it is UK becuase they use in the same letters
UPDATE:
there is away to tranlate variable (string) to user language and if editText contain english so no tranlate ?
like this :
string = "song" ;
englishletter = "abc..." ;
for(int i = 0 ; i < string.length(); i++ ){
if( string.contains(englishletter.substring(i,i+1)) {
num++;
}
}
if (num==0){
system.out.print(string.tranlsate());
} else {
system.out.print(string) ;
}

I don't think there's anything in Android that will do this for you. I would suggest integrating a library like this one: language-detection

Unusual android logic operator not working comparing two strings

I'm trying a simple check. If a string name locale has "es" as value.
public String locale =
Locale.getDefault().getLanguage().toLowerCase().toString();
// ...
Log.v(tag, "Idioma del sistema: «" + locale +"»");
if (locale != "es") {
showDialog(R.string.warningTitleDialog,
"We are sorry that this tool is only available in Spanish " +
"language. See Author menu item for more information. [" +
locale + "]");
locale = "en";
}
adb logcat shows "es" as content of string "locale" but code inside the condition is being executed.

It seem that problem is not of android or of logic this is in JAVA.
Try this and tell us what is happening
if(!locale.equals("en"))
{
//Your Code
}

Never use != or == in association with strings. Try the method equals like this:
if(locale.equals("es"))
This will return true if the strings locale and "es" contain the same character
sequence. Because the equals( ) method compares the characters inside a String object. The == operator compares two object references to see whether they refer to the same instance.
See What is the difference between == vs equals() in Java? for more information.

Using text to speech APIs in android application

I want to use TTS (Text to Speech) APIs in my android application.Now i have one quetions - Is it support TURKISH language ?
I also want to highlight word in textview when that perticular word is being spoke.
How can i do it ?
Can anybody help me ?
Thanks in advance !

Does it support TURKISH language
This may vary on different handsets/flavours of Android. You can check it out for yourself using the
mTTS.isLanguageAvailable(new Locale("tr", "TUR"));
I also want to highlight word in textview when that particular word is being spoke.
Well you have a TextToSpeech.OnUtteranceCompletedListener(), to use this you have to speak() each word, one at a time.

The TTS engine that ships with the Android platform supports a number of languages: English, French, German, Italian and Spanish. Also, depending on which side of the Atlantic you are on, American and British accents for English are both supported.
http://developer.android.com/resources/articles/tts.html

You should use Locale type variable.
final Locale locale = new Locale("tr", "TR");
tts = new TextToSpeech(getApplicationContext(), new
TextToSpeech.OnInitListener() {
#Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
int result = tts.setLanguage(locale);
if (result == TextToSpeech.LANG_MISSING_DATA
|| result == TextToSpeech.LANG_NOT_SUPPORTED) {
Log.d("class name", "tts error ");
}
} else {
Log.d("class name", "tts error ");
}
}
});
tts.speak("write here what you want in Turkish", TextToSpeech.QUEUE_FLUSH, null);

Get available locales for text to speech (TTS)

I'm working on a text-to-speech implementation of a flashcard program. Text in different languages should be read out. In order to do this properly the user has to select the language of the text to read (will be stored and used later without question).
Is there a possibility of getting the available TTS languages on an Android system? If not, is there a possibility of getting all availably locales on the system?
I guess, I got it: getAvailableLocales() and tts.isLocaleAvailable(locale)

Someone else has done the hard work, at http://kaviddiss.com/2012/08/12/android-text-to-speech-languages/
To save you time, here's their code extract
TextToSpeech tts = ...
// let's assume tts is already inited at this point:
Locale[] locales = Locale.getAvailableLocales();
List<Locale> localeList = new ArrayList<Locale>();
for (Locale locale : locales) {
int res = tts.isLanguageAvailable(locale);
if (res == TextToSpeech.LANG_COUNTRY_AVAILABLE) {
localeList.add(locale);
}
}
// at this point the localeList object will contain
// all available languages for Text to Speech
The results depend on which TTS engine has been selected. For instance, one of my phones includes both the Pico-TTS and Google-text-to-speech engines.
Q-Smart (Vietnamese Phone with Google TTS as selected engine)
D/SpeakRepeatedly( 3979): Engine Google Text-to-speech Engine:com.google.android.tts
D/SpeakRepeatedly( 3979): Engine Pico TTS:com.svox.pico
D/SpeakRepeatedly( 3979): German (Germany):German:de_DE
D/SpeakRepeatedly( 3979): English (United Kingdom):English:en_GB
D/SpeakRepeatedly( 3979): English (United States):English:en_US
D/SpeakRepeatedly( 3979): English (United States,Computer):English:en_US_POSIX
D/SpeakRepeatedly( 3979): Spanish (Spain):Spanish:es_ES
D/SpeakRepeatedly( 3979): French (France):French:fr_FR
D/SpeakRepeatedly( 3979): Italian (Italy):Italian:it_IT
D/SpeakRepeatedly( 3979): Portuguese (Brazil):Portuguese:pt_BR
D/SpeakRepeatedly( 3979): Portuguese (Portugal):Portuguese:pt_PT
And with Pico selected
D/SpeakRepeatedly( 4837): Engine Google Text-to-speech Engine:com.google.android.tts
D/SpeakRepeatedly( 4837): Engine Pico TTS:com.svox.pico
D/SpeakRepeatedly( 4837): German (Germany):German:de_DE
D/SpeakRepeatedly( 4837): English (United Kingdom):English:en_GB
D/SpeakRepeatedly( 4837): English (United States):English:en_US
D/SpeakRepeatedly( 4837): English (United States,Computer):English:en_US_POSIX
D/SpeakRepeatedly( 4837): Spanish (Spain):Spanish:es_ES
D/SpeakRepeatedly( 4837): French (France):French:fr_FR
D/SpeakRepeatedly( 4837): Italian (Italy):Italian:it_IT
Note:
Portuguese isn’t listed in the TTS Settings UI. When I select Portuguese programmatically in my app it speaks with a Portuguese accent! FWIW here's my code to select Portuguese (it accepts both Brazilian and Portuguese locales).
if (locale.getDisplayName().startsWith("Portuguese")) {
Log.i(SPEAK_REPEATEDLY, "Setting Locale to: " + locale.toString());
tts.setLanguage(locale);
}
}

Since different TTS engines return different results for isLanguageAvailable, I found that the following solution works best on several common TTS engines.
Please also note that starting with Android Lollipop, there is a simple method in TextToSpeech called getAvailableLanguages that does that easily for you (if the device is running API 21 or later).
You need to call the following methods in the onInit method of your OnInitListener assigned to the TextToSpeech object.
ArrayList<Locale> languages;
TextToSpeech initTTS;
private void initSupportedLanguagesLollipop()
{
Set<Locale> availableLocales = initTTS.getAvailableLanguages();
for (Locale locale : availableLocales)
{
languages.add(locale);
}
}
private void initSupportedLanguagesLegacy()
{
Locale[] allLocales = Locale.getAvailableLocales();
for (Locale locale : allLocales)
{
try
{
int res = initTTS.isLanguageAvailable(locale);
boolean hasVariant = (null != locale.getVariant() && locale.getVariant().length() > 0);
boolean hasCountry = (null != locale.getCountry() && locale.getCountry().length() > 0);
boolean isLocaleSupported =
false == hasVariant && false == hasCountry && res == TextToSpeech.LANG_AVAILABLE ||
false == hasVariant && true == hasCountry && res == TextToSpeech.LANG_COUNTRY_AVAILABLE ||
res == TextToSpeech.LANG_COUNTRY_VAR_AVAILABLE;
Log.d(TAG, "TextToSpeech Engine isLanguageAvailable " + locale + " (supported=" + isLocaleSupported + ",res=" + res + ", country=" + locale.getCountry() + ", variant=" + locale.getVariant() + ")");
if (true == isLocaleSupported)
{
languages.add(locale);
}
}
catch (Exception ex)
{
Log.e(TAG, "Error checking if language is available for TTS (locale=" + locale +"): " + ex.getClass().getSimpleName() + "-" + ex.getMessage());
}
}
}

Find all available TTS Locale on the device using following function.
Locale.getAvailableLocales()
Output of: Arrays.toString(Locale.getAvailableLocales())

Starting from Android 5.0 (API level 21), TextToSpeech.getAvailableLanguages has been added to fetch a set of all locales supported by the TTS engine.
TextToSpeech tts; // assume this is initialized
tts.getAvailableLanguages(); // returns a set of available locales
I have also noticed that the set of locales returned by TextToSpeech.getAvailableLanguages might not be a strict subset of Locale.getAvailableLocales, i.e. there might a locale supported by the TTS engine that isn't supported by the system.
