Does the android support Unicode natively?
But in String.xml we have to edit it with UTF-8 ??
Any way to check the string's encoding? unicode or utf-8 ?....
Android does support Unicode.
Since you seem to be confused about the relationship between UTF-8 and Unicode, I recommend that you save yourself a lot of pain and just read The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets.
If you mean UTF-16 or UTF-8 - Android works with UTF-8
Android supports Unicode characters in UTF-8 encoding - but lacks proper fonts and a complex text rendering system do display many scripts and languages properly.

I'm trying to display unicode characters (more specifically emojis) in my android application. Many of the unicode characters from http://apps.timwhitlock.info/emoji/tables/unicode seem to be unsupported by the default android font system.
For example:
myTextView.setText("\u1F602 \u1F603 \u263A");
will only correctly display the last unicode character (\u263A) according to the link above. Like I said, I'm guessing this a result of unsupported unicode characters by the default font. How do I go about supporting those unicode characters with the default android representation? Do I need to choose a new font, and if so, how do I determine if that font supports what I need?
Thanks!
Certain unicode characters in the Miscellaneous range would be nice to use, but most phones display them as emoji and that is unwanted because then they can't be styled by CSS font declarations. I know there's a fix for iOS, but I have not found a solution for Android. Is it possible to disable them?

Had the same problem, found the answer on another stack overflow question which worked for me:
add ︎ at the end of the string with the Unicode characters you do not want to be replaced with emoji icons.
How to prevent Unicode characters from rendering as emoji in HTML from JavaScript?
Google Chrome, desktop version 75, seems to disambiguate its approach to rendering Unicode characters based on the first Unicode escape it encounters while loading a page. For instance, when parsed as the first HTML Unicode escape in a page source, and having no emoji equivalent, ⏷ seems to clarify to Chrome that the page contains escapes not to be rendered as emoji. I have not tried this in Android Chrome.
I'm developing an Android app and when it was suposed to write words like "não" or "cabeça", with characters with "~" or "ç" for example, it writes "ã" or "ç". I already checked source files encoding and it is UTF-8.
Looks like UTF8 interpreted as ISO-8859-x.
In theory, you could supply the javac compiler -encoding UTF-8 on the command line but that would be the wrong solution.
Instead, move all your user-facing strings to an XML resource file. In there unicode character encoding works out of the box.

Hopefully this is a quick answer, needing only a link to a credible source.
Would anyone know where to find a list of XML text encoding formats that are supported by iOS (specifically NSXMLParser) and it's equivalent for Android?
Specifically, is UTF-16 supported?
Thanks in advance.
I can't find a source from Apple specifically stating that UTF-16 is supported, but the XML spec states that all XML parsers MUST accept both UTF-8 and UTF-16 encodings so I think it's safe to assume that NSXMLParser conforms to that. You can always just test it and see if it supports any given encoding.
For encodings that actually are unsupported, you can use NSString/CFString methods to convert them to supported encodings.
After creating a database, i'm using a listview do display some lines of it. I'm facing a encoding problem trying to display a 'Ç' or 'ç' and many other characters. What is the correct approach to solve the problem?

I'd recommend to convert all the text you have to UTF-8. Android's default charset is UTF-8 and you can configure your tools (eclipse, operating system default encoding, etc.) to always use UTF-8 - this way any text you will be entering or copying into files will be UTF-8 and your worries are much less.
If you have some other external data sources like files or HTML pages, you should convert them to UTF-8 first. There are number of tools you can use - various text editors for Windows/OSX (Notepad++ my favourite), iconv unix command line tool etc. to convert between various encodings.
UTF-8 is also used by JSON which is most commonly used format for mobiles for data exchange.
You have to check defaultCharset vs your desired charset.
and you have the Charset utility at your disposal.
