Add new line character in remote config text

I'm doing Firebase RemoteConfig integration. In one of the scenarios, I need to break a text line, so I tried to use new line character (\n).
But this is not working, it is neither displaying as an extra character nor creating another line.

My solution is replace \n manually (assuming that in Firebase Console you put property for TITLE as "Title\nNewLine"):
FirebaseRemoteConfig.getInstance().getString(TITLE).replace("\\n", "\n")

Try using an uncommon character like two pipes || and then replacing every occurance of those with a newline after you do getString() in the code.

You can insert encoded text(with Base64) to Firebase panel.
After, decode the String from your Java class and use it.
Like
byte[] data = Base64.decode(base64, Base64.DEFAULT);
String text = new String(data, "UTF-8");

The trick (which actually works for all HTML tags supported on your target platform) is to wrap the String in a JSON Object on RemoteConfig, like so:
{
"text":"Your text with linebreaks...<br><br>...as well as <b>bold</b> and <i>italic</i> text.
}
On the target platform you then need to parse the JSON and convert it back to a simple string. On Android this looks like this:
// extract value from JSON
val text = JSONObject(remoteConfig.getString("remoteConfig_key")).getString("text")
// create Spanned and use it
view.text = HtmlCompat.fromHtml(text)

So what worked for me is to use "||" (or some other character combination you are confident will not be in the string) as the new line character. Then replace "||" with "\n". This string will then display properly for me.
For some reason sending "\n" in the string doesn't get recognized as expected but adding it manually on the receiving side seems to work.

To make the suggestion mentioned above, you can try this code(that can be generalized to "n" number of elements). Simply replace the sample text with yours with the same format and add the amount of elements
String text="#Elemento1#Elemento2#Elemento3#";
int cantElementos=3;
arrayElementosFinales= new String[cantElementos];
int posicionNum0=0;
int posicionNum1;
int posicionNum2;
for(int i=0;i<cantElementos;i++){
posicionNum1=text.indexOf("#",posicionNum0);
posicionNum2=text.indexOf("#", posicionNum1+1);
char [] m = new char[posicionNum2-posicionNum1-1];
text.getChars(posicionNum1+1, posicionNum2,m,0);
arrayElementosFinales[i]=String.valueOf(m);
posicionNum0=posicionNum2;
}

Use Cdata in the remote config in combination with "br" tag and HTML.fromHtml() .. for eg.
<![CDATA[ line 1<br/>line 2]]>

display special character correctly

I have got the problem, that I can't display special characters like 'ß, ö, ä, ü' in my app.
The result is like this:
Or like this:
In Android Studio I get no error or warning and I am using the windows-1251 encoding.
In gradle I added this line: compileOptions.encoding = 'windows-1251'
It shall be german encoding.
How to fix that?
I actually can change special characters like 'ß' from predefined Strings with Html.fromHtml( unicode of the special character) like Html.fromHtml ( "&#223" )
But what if a non predefined String contains a special Character? I have tried to simple replace the special character like this:
String neuer_String = get_street_adress.replace ( "ß", Html.fromHtml ( "&#223" ) ) ;
straße.setText ( "Stra" + Html.fromHtml ( "&#223" ) + "e: " + neuer_String);
But this doesn't work, because the string FriedhofstraÃe for example should be Friedhofstraße. So there is no character 'ß' in the string.
I also tried to change the font with Typeface but a exception is thrown: "native typeface cannot be made"

It's probably 'cause of the font in your device.
The way you can resolve this is by coding a Typeface out of a working font that you have tested.(e.g in Word,etc)
Typeface typeface = Typeface.createFromAsset(getAssets(), "fonts/theNameOfTheFont.ttf");
Remember to place the code in fonts folder in assets. If you don't have one, create it.
Using UTF-8 encoding "might" solve your problem.

It's strongly recommended to use UTF-8 encoding.
With UTF-8 encoding, you can easily use the unicode value in your string.xml.
Here the a Link to XML character Entities List.
For example for ß use <string name="text szlig">text ß</string>

Go to the settings of Android Studio. In the File Encoding tab, make everything be formatted as UTF-8.
If the problem still persists, then the problem is in the font you are using as it may not support special characters.
I have found a solution for your problem, check it:
You can save all your strings with special characters in your strings.xml like:
<resources>
<string name="street">Straße</string>
</resources>
Then retrieve them in code like:
String street = getResources().getString(R.string.street);
You can definitely try other german characters out. Hope that works for you!

Android and Accents Missing

I'm new to android. I've created an EditText and if I assign the property android:text from xml code using a word with accents (I try with àèìòù) I see the text displayed correctly.
If I try to assign with string value edit_message, I get the unknown character symbol. This is my code:
EditText editText=(EditText)findViewById(R.id.edit_message);
editText.setText("àèìòù");
I think it's an encoding problem, but it seem strange.
The string shouldn't be UTF-8 by default?

Use HTML entity-codes via Html.fromHtml:
editText.setText(Html.fromHtml("àé ...");
A list of entity codes is available here:
http://symbolcodes.tlt.psu.edu/web/codehtml.html
You could use the method htmlEncode of the TextUtils class to automaticaly convert your input-text to an encoded-format:
string encodedText = TextUtils.htmlEncode("àèìòù");
editText.setText(Html.fromHtml(encodedText));

How to set unicode in textview to show emoji in android?

I am getting some Unicode string(emoji icons) from server in json string format.
My problem is strange and I am trying for last two days to resolve this issue. When I parse json and store all the Unicode string in an ArrayList<String> and try to set the text on TextView by getting value from the same ArrayList then it shows Unicode characters as :
Ghcghchgc\ud83d\ude03\ud83d\ude03fyju\ud83d\ude0c6\u20e3
and when the same string I set on textview by passing static value as :
textview.settext("Ghcghchgc\ud83d\ude03\ud83d\ude03fyju\ud83d\ude0c6\u20e3")
then the textview is showing perfect emojis.
I am stuck at this point. Can anybody please help me to resolve this issue or tell me if I am doing something wrong.

This sounds like you want to unescape your string that you've got from JSON. If you don't mind adding a library, Apache Commons has a String.unescapeJava function which does what you need. If you don't want to add that library, see this answer.

This is what has worked for me ( Kotlin version ):
textView.text = String(Character.toChars(0x1F389))

Setting Danish Character Text

I am getting some strings from json. My string contains special characters like "æ" from Næstved an many more like "ø" from køkken. But When I set Text these strings to ant textview, I get my strings printed in unusual way.
Example: For køkken I get k&oslash ;kken.
I think I need to encode or decode my string somewhere but where I don,t know.
Please help.
Thanks in advance

The displayed version of your string represents an HTML encoded entity. You might want to verify that it is not coming in this way in your JSON data, but in any case, to decode it you can use the StringEscapeUtils.unescapeHtml4 method from Apache Commons Lang:
final String escaped = "køkken";
System.out.println(StringEscapeUtils.unescapeHtml4(escaped));
Output:
køkken

Did you check out the Latin Coding for your characters? I know the Ash character can be coded with æ and will show up æ in the browser.
Here is the a list of codes
Hope this helps!
