Is it possible to add custom language by adding custom font in android devices?

Is it possible to add my language(ladakhi) support in android because I don't see my language in android system by default so I wanted to add it manually. The way I am trying to do was by adding custom font (.tff) in my app and add to the android system.
But I am quite not sure whether it is possible or not ? If so please share me a resource or link where I can look up to.
[Expected Result]
Just like how we change android system language to hindi, kannada etc.I wanted to add my language support in android system.
Regards

A similar question is asked here. The answer is you can't unless you download the android source and add a new language translation. For more you can #Romain Guy answer here

What is the help file format

ALL,
We are trying to rewrite a huge software that is written in wxWidgets + Qt to run on Android tablet and we are trying to rewrite it in JAVA (as it is a natural language for development in Android). Our old system is using RoboHelp to generate Help files and then the RoboHelp libraries are put on the Client system for the Search functionality.
One of the pieces that needs to be redefined is a Help system (and also a Context-Sensitive Help).
I just tried to search for which file format (html, xml, etc) can be used to implement file formats. However, Google give me a bunch of links for video/audio and all other stuff but nothing is related to Help system. I believe it is because Help in Android applications is not really defined and there is not to many applications written for Android that requires Help system.
Does anybody here have an idea? Google Material Design does not say anything in this regards - they just tell you that there should be a Help button with a possible drawer implementation and that about it. But there is nothing about Help content file format.
The Help system should support navigation and search capabilities.
Thank you for any suggestions you can provide

Delphi XE5 right to left languages don't appear as they should in android

as the title says , a text from a RTL language like persian or arabic doesnt show well in android
for example the word "سلام" shows as "م ا ل س".
this problem happens even in text inputs (which i thought they were native and native android textboxes support that)
is there a way to fix this?

Lack of Bidirectional and Glyph Shaping support is a known restriction of the FireMonkey platform, on all targets (including Windows and Mac OSX).
We will have to wait for "native controls" for Android as third party components for FireMonkey, as it does exists for iOS - see http://www.tmssoftware.com/site/tmsicl.asp for instance.
I've found this great blog article with source code about Android Native controls for Lazarus/FreePascal which is quite interesting. But this won't work with the "NextGen" Delphi compiler, which is currently going in a diverse direction in respect to FPC (e.g. with the ObjectivePascal mode).
Since it uses native Android controls, it should not suffer from the same restrictions as FireMonkey do.

the best solution is fmxrtl you can find at
http://www.fmxrtl.com/

As per LURD's suggestions.
Download and use D.P.F Delphi Android Native Components and/or D.P.F Delphi iOS Native Components.
That will fix the problem in XE7 and prior.
According to the documentation with the Delphi XE8 beta the problem is fixed there as well.
As a last resort (if you feel up to it), someone has taken the effort to patch the XE5 source code to enable BiDi support. See: https://docs.google.com/file/d/0BwumWe43CaijVDRQZzNQbXNSLWc/edit?usp=sharing

Rendering Kannada (Indic) Text on Android

I was recently developing an android application where I wanted to display kannada text in the TextView. I went through this link, now the problem is the glyphs(character sequence) are not rendered/interpreted properly.
I also found this discussion pretty usefull .
Now my question is - "Is it possible to integrate a layout/shaping engine (responsible for rendering the text properly) in an application.
Any help in this regard would be helpful.
Thanks !!

Use Bitmap fonts and your own rendering engine till Android supports

What version of Android are you targeting? Pre-2.3 Android has very poor support for any Indian language whatsoever. 2.3 introduced support for Hindi, but Dravidian languages are still missing. Based on this fact is my hunch that Android 2.3 and later probably might render Kannada text better.
Also, emulators have known issues with text rendering in some languages. I suggest testing on a real device.
