"getDisplayLanguage()" always returning "English"

I need to get the current language selected in the Android device. When I use below code:
Log.v("Language: ", Locale.getDefault().getDisplayLanguage());
Log.v("Language: ", getResources().getConfiguration().locale.getDisplayLanguage());
The output is always same:
V/Language:: English
Below picture from android emulator selected language:
When I change the language of emulator, I can get the logs in the picture on the Android console.(But getDisplayLanguage() function returning English)

String locale = context.getResources().getConfiguration().locale.getDisplayName();
String locale = java.util.Locale.getDefault().getDisplayName();
They are different. The first can change if the user switches the Locale.
The second is the one that is pre-installed on the phone. It never changes no matter what the user does.
Happy Coding :)

Displaying Unicode string in Users control in Xamarin (Android)

Basically, i have a list of Nepali Unicode strings something like {"युनिकोड १ ","युनिकोड २","युनिकोड ३"}.
Now, Firstly, I have a text view in Xamarin (Android) and tried to set the text property using couple of methods:
UnicodeTextView.Text="युनिकोड १"; //direct method
var font = Typeface.CreateFromAsset(_activity.Assets, "kantiput.TTF");//kantiput.TTF Is a Nepali font.
UnicodeTextView.Typeface = font;
var font = Typeface.CreateFromAsset(_activity.Assets, "kantiput.TTF");
UnicodeTextView.SetTypeface(font, TypefaceStyle.BoldItalic);
and none of them worked.
When using the first option nothing was displayed, and on working with last two
and there were some BOX character visible.
For first case when i directly tried to set the value:
Before setting value:
After setting value:
Samething with the ListAdapter.
Can anyone suggest me how can we display unicode sentences in TextView, EditText, Toast ?
I want result something like this :
with TextView :
and here is the weird behavior :
and i tried all those code that are in comment too. Still didn't find any luck.

I am working in android.
In toast I checked like the following:
Toast.makeText (this, "\u0c05 \u0c06", Toast.LENGTH_SHORT).Show();
For first two letters of Telugu alphabet s. It worked.
If you have the font file you can obtain unicode codes for the various glyphs in the online software available at
https://opentype.js.org/index.html
Under page glyph inspector.

I tested your code, the first direct method UnicodeTextView.Text="युनिकोड १"; works fine by my side both with single TextView or TextView in ListView.
Or you may try this code:
if (Android.OS.Build.VERSION.SdkInt >= Android.OS.Build.VERSION_CODES.N)
{
UnicodeTextView.Text = Android.Text.Html.FromHtml("युनिकोड १", Android.Text.FromHtmlOptions.ModeLegacy).ToString();
}
else
{
UnicodeTextView.Text = Android.Text.Html.FromHtml("युनिकोड १").ToString();
}

How to force tesseract to recognize a single character, instead of ignoring it?

I have been using tesseract (tess-two to be more precise)to make an app in android to recognize certain non conventional symbols. The purpose is to identify the symbol and redirect to the description of said symbol.
The symbols can be recognized almost perfectly whether they are alone in the image or they are next to each other... except for two (the ones below).
symbols omitted from recognition
Both of these symbols are not recognized when alone, BUT THEY ARE CORRECTLY RECOGNIZED if they are next to any other symbol.
For example:
Not recognized
_
Correctly recognized
_ b
_ y _
Problem is that they are not mismatched with other symbols, but instead they are ignored completely. This occurs to me when calling:
TessBaseAPI baseApi;
...
String text = baseApi.getUTF8Text();
The returned string is always null. Like if it didn't even recognize the black regions to begin with.
Anyone knows how I could fix this?
UPDATE:
To make it more clear here is my full code when initializing tess.
TessBaseAPI baseApi = new TessBaseAPI();
mainBitmap = mainBitmap.copy(Bitmap.Config.ARGB_8888, true);
baseApi.setDebug(true);
baseApi.init(MainActivity.DATA_PATH, MainActivity.lang);
baseApi.setPageSegMode(TessBaseAPI.PageSegMode.PSM_SINGLE_CHAR);
baseApi.setVariable("tessedit_char_whitelist","abcdefghijklmnopqrst");
baseApi.setImage(mainBitmap);
mainBitmap.recycle();
mainBitmap = null;
// Iterate through the results.
ResultIterator iterator = baseApi.getResultIterator();
String lastUTF8Text;
float lastConfidence;
iterator.begin();
do {
lastUTF8Text = iterator.getUTF8Text(TessBaseAPI.PageIteratorLevel.RIL_SYMBOL);
lastConfidence = iterator.confidence(TessBaseAPI.PageIteratorLevel.RIL_SYMBOL);
Log.i("string, intConfidence",lastUTF8Text+", "+lastConfidence);
} while (iterator.next(TessBaseAPI.PageIteratorLevel.RIL_SYMBOL));
My whitelist goes from a range of "a" to "t" because I made a font corresponding to the symbols I had to use and mapped them to each one of those letters.

I would try and set the page segmentation mode to single char.
TessBaseAPI.PageSegMode.PSM_SINGLE_CHAR

masked input not working in android mobiles?

I am using the digitalbush masked input jQuery plugin. It is working fine in web browsers and the iPhone browser perfectly, but it is not working for Android mobile devices.
My issue :
mask is
in input field _ - _ - ___.
When I type numbers it will 12345685555___--
Example: http://rossbender.com/temp/mask.html
Any suggestions? How can I solve this?
Thanks
Prasad.

I resolved this issue with three actions, which have fixed this for all Android 4.0+ phones:
Update masked-input to at least version 1.4
Add type="tel" to the input, to trigger the numeric keyboard
Remove the input's maxlength attribute or set it to a value certain not to interfere with the caret action, like 20.

I tried using the raw script that Jonathan Rowny mentioned, but I was still having the same problem on an S3 - Chrome browser. I think it has something to do with inputs type="tel" and/or type="number". I ended up having to use another plugin. http://igorescobar.github.io/jQuery-Mask-Plugin/
jquery-mask (not to be confused with jquery-masked-input) is very similar but the syntax was slightly different. Hope this helps anyone else with this issue.
jquery-masked-input syntax:
$("#phone").mask("(999) 999-9999");
VS
jquery-mask syntax: ('#phone').mask('(000) 000-0000');

This was fixed awhile ago but for some reason the distribution posted on the website never took the changes. If you grab from the raw source, the fix works: https://raw.githubusercontent.com/digitalBush/jquery.maskedinput/master/src/jquery.maskedinput.js

After trying different mask libraries (Inputmask, ui-mask, ngMask) I ended up using jQuery-Mask-Plugin https://igorescobar.github.io/jQuery-Mask-Plugin/ which works pretty well and is also lightweight and well documented and has angularjs, react ,... samples.

I just ran into this problem and resolved it by removing the attribute type="number" from the asp textbox. After that masked input worked even on mobile devices.

The library used in the question is no longer being maintained. I switched my application to jQuery Mask Input as it works great, has a very similar base init call to the former library making for an extremely easy transition and, at the time of this post, jQuery Mask Input is regularly maintained at GitHub.
My issue was with the phone number masker moving the cursor back to the second position when 3 or 4 digits were entered. The cursor continued to act odd after that point. The problem was noticed using jQuery Masked Input v1.4.1 (old library) in android tablets using Chrome post major version 51.

To further enhance the accepted answer of Tony Brasunas, add following snippet in jquery.maskedinput.js for point number 3 to dynamically increase maxlength so it doesn't interfere with caret action.
Remove the input's maxlength attribute or set it to a value certain not to interfere with the caret action, like 20.
defs = $.mask.definitions;
tests = [];
partialPosition = len = mask.length;
firstNonMaskPos = null;
//insert snippet below
if (chrome && android) {
console.log("chrome && android");
var allAllowedRegExps = '';
jQuery.each(defs, function (key, value) {
allAllowedRegExps = allAllowedRegExps + key;
});
allAllowedRegExps = allAllowedRegExps.replace(/\[/g, '');
allAllowedRegExps = allAllowedRegExps.replace(/\]/g, '');
allAllowedRegExps = '[^' + allAllowedRegExps + ']';
var re = new RegExp(allAllowedRegExps, "g");
var actual = mask;
var replacedVal = actual.replace(re, "");
var actualValue = actual.length - replacedVal.length;
if ($(this).attr('maxlength') !== undefined) {
$(this).attr('maxlength', parseInt(this.attr('maxlength')) + parseInt(actualValue));
}
}
mask = String(mask);

This can be a quick fix:
var ua = navigator.userAgent;
var isAndroid = /Android/i.test(ua);
var isChrome = /Chrome/i.test(ua);
// Fix masking on Chrome for mobile devices
if (isAndroid && isChrome) {
$('.price_input').attr('type','tel');
}

It worked for me by using 1.4.1 and setting the max length to one plus the number of chars in the mask. The mask limited the actual input and the max length +1 fixed the problem of not being able to type numbers in the field.

Android: access "system"-drawables

I'm currently working on an app to display the battery status and I'd like to use Android-drawables instead of own images to reduce the app size.
I've found this page which lists available images and the availability for each SDK-version:http://www.fixedd.com/projects/android_drawables_display
My question: How can I access the "system"-drawables? If you click on the link and choose the tab "Status", there are some battery-drawables like "stat_sys_battery_0", but I can't access it, Eclipse doesn't offer intellisense for it and won't compile the app if I use one of those drawables.
As those drawables are part of all SDK-versions, I'd think I should be able to use them, or are those "special" drawables protected in a way so they can only be used by system-functions (and not apps)?
Any idea is appreciated.

Hope this is what you were looking for:
private BroadcastReceiver mBatInfoReceiver = new BroadcastReceiver(){
#Override
public void onReceive(Context arg0, Intent intent) {
int level = intent.getIntExtra("level", 0);
int batteryIconId = intent.getIntExtra("icon-small", 0);
Button toolBarBattery = (Button) findViewById(R.id.toolBarButton);
LevelListDrawable batteryLevel = (LevelListDrawable) getResources().getDrawable(batteryIconId);
batteryLevel.setLevel(level);
toolBarBattery.setBackgroundDrawable(batteryLevel);
}
};

I've found another link with information that not all drawables are public. It doesn't say why some drawables would be private, but I guess I'll have to live with the fact and copy the needed images to my app.http://androiddrawableexplorer.appspot.com/
NOTE: Some of the images in the Android jar are not public and therefore cannot be directly used (you can copy them to you own application, but can't reference them via the "android" package namespace).

There actually seems to be a way to access the system icons, but it's not really working as stated in the documentation, but I'll add it in case somebody is interested:
intent.getIntExtra(BatteryManager.EXTRA_ICON_SMALL, -1)
Will get you the resource-ID of the icon that matches the current battery-status:http://developer.android.com/reference/android/os/BatteryManager.html#EXTRA_ICON_SMALL
Extra for ACTION_BATTERY_CHANGED:
integer containing the resource ID of
a small status bar icon indicating the
current battery state.
However, it always returns the same icon, no matter what the actual battery level is. Finding the icon by just trying random numbers may work, but I don't know if the IDs are consistent throughout the SKD-levels as well as different machines, so I'd rather not rely in that.
