Issue with float.Parse in Unity Android App

I develop an Android app. If I call
float.Parse("51.552058")
in Editor or App on my Mac Book (Language Setting English), it works fine. After publishing to Android (Language Setting German) the result of the Parse operation is not "51.552058" anymore but "5,155211E+09". I understand that this might be related to the device's language but I still don't really understand what is happening and why.
I also tried following with no success:
float.Parse("51.552058", System.Globalization.NumberStyles.Any)
float.Parse("51.552058", System.Globalization.NumberStyles.AllowDecimalPoint)
Did anyone stumble over this before?

float.Parse is culture dependent.
See e.g. from NumberFormatInfo
// '1,034,562.91' --> 1034562.91 (en-US)
// '1,034,562.91': FormatException (fr-FR)
// '1,034,562.91' --> 1034562.91 (Invariant)
Reason here is that in EU cultures the , is usually the decimal separator while the . is used as the group separator. So from the example above the correct format for fr-FR would be 1.034.562,91
You probably rather want to use CultureInfo.InvariantCulture like
float.Parse("51.552058", CultureInfo.InvariantCulture);
or directly NumberFormatInfo.InvariantInfo
float.Parse("51.552058", NumberFormatInfo.InvariantInfo);
which simply has defined
NumberDecimalSeparator .

How to display source code "prettily" in android app

everyone.
[What I'd like to do]
To display source code "prettily" in android app. Like this.
At least if there are indents, it's fine.
[Why?]
Because I'm developing an android app where users can see Views and its source code at the same time.
[Issue]
Showing source codes on TextView looks ugly. A lot of escape characters needed for <> and the text layout collapsed. Googling and searching on Stackoverflow didn't give me any useful information.
Any help would be appreciated. Thanks!
(update 2015/11/23)
These link might be useful when you use WebView to display source codes.
- How can I display HTML source code within a HTML website? [duplicate]
- How to display source code with indent in a web page? HTML? CSS?

Displaying the text in a WebView is a great idea as you can now use javascript APIs like Google's Code Prettify
I believe SO uses it ;)
The comments in prettify.js are authoritative but the lexer should
work on a number of languages including C and friends, Java, Python,
Bash, SQL, HTML, XML, CSS, Javascript, Makefiles, and Rust.
It works passably on Ruby, PHP, VB, and Awk and a decent subset of
Perl and Ruby, but, because of commenting conventions, doesn't work on
Smalltalk, OCaml, etc. without a language extension.
Other languages are supported via extensions:
Apollo; Basic; Clojure; CSS; Dart; Erlang; Go; Haskell; Lasso; Lisp,
Scheme; Llvm; Logtalk; Lua; Matlab; MLs: F#, Ocaml,SML; Mumps;
Nemerle; Pascal; Protocol buffers; R, S; RD; Rust; Scala; SQL; Swift;
TCL; Latek; Visual Basic; VHDL; Wiki; XQ; YAML

I think this question is a tricky one. I tried to google myself and only find this library
https://android-arsenal.com/details/1/2049
which supports different text appearence. Hope this will help you out.

Russian text is not working in Android game when ported from iOS using Apportable SDK

I have successfully ported our game to Android from iOS using Apportable starter SDK.
I have come across a issue in which the device is decoding Russian text of the game , i have included screen shots and where i have given such Russian texts in xcode.As you see from the i have typed the word "Test" in English which is displayed properly and whereas the Russian text is displayed in some form of code.
NSArray *objects = [NSArray arrayWithObjects:#"\n Test Разъезжая по сказочным землям и устраивая веселые дискотеки, я добрался до Пушляндии. Я много слышал о веселых и дружных жителях этой страны - Пушистиках. Узнав о моем появлении, они шумной толпой прибежали на мою вечеринку..."];
Stack overflow is not allowing me to add screenshots so i am adding links.The first screenshot shows the way i want the text to display in android adb second screenshot shows the current way its displayed.
I will provide more detailed description or code if required.

Few devices doesn't support Gujarati language packs.
You need to define css and apply it to your webview.
Below post may help you as well.

Correcting Hindi (Unicode) rendering in Android

I successfully added a custom typeface (DroidSansFallBack.ttf) to show Hindi characters instead of Blocks on Pre ICS . All is working well on 4.1+ in any case.
But the rendering order is wrong on Froyo and Gingerbread.
I understand it is not resolved http://code.google.com/p/android/issues/detail?id=4153
What are the possible workarounds to correct the rendering? (I don't want to use images )
EDIT:
Example,
दिन string from values-hi renders as दनि
नक्षत्र renders as नक् ष त र
(On 4.1+ everything renders correctly)

I have a alternative solution for your problem but not exact...
use font....
Typeface tf = Typeface.createFromAsset(getAssets(),"Hindi-SARAL1.TTF");
for नक्षत्र use .......
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText("n95");
tv.setTypeface(tf);
and for दिन........ unicode value continues no gap.. i have given a space between &# and 2367;
tv.setText(Html.fromHtml("&# 2367;&# 2342;&# 2344;"));
tv.setTypeface(tf);

I could not find a simple work around for fixing the rendering everywhere. So finally I had to limit the Hindi language feature to devices having android version 4.0 or later.
