I have declared a long string in
string.xml of an application.
Declared like this
But this gives the following error :
post your complete string. Though, my guess is there is an apostrophe (‘) character in your string. replace it with (\’) and it will fix the issue. for example,
//strings.xml <string name="terms"> Hey Mr. Android, are you stuck? Here, I\'ll clear a path for you. </string>
Apostrophes in the strings.xml should be written as
In my case I had an error with this string in my strings.xml and I fixed it.
<item>Most arguments can be ended with three words, "I don\'t care".</item>
Here you see my app builds properly with that code.
Here is the actual string in my app.
You have to put \ before an apostrophe. Like this \’ , Also check that you are editing strings.xml and not values.xml (android studio directs you to this file when shows the error). Because if you edit values.xml and try to compile again, the error persists. This was happening to me recently.
Escaping apostrophes and quotes
If you have an apostrophe or a quote in your string, you must either escape it or enclose the whole string in the other type of enclosing quotes. For example, here are some stings that do and don’t work:
<string name="good_example">"This'll work"</string> <string name="good_example_2">This\'ll also work</string> <string name="bad_example">This doesn't work</string> <string name="bad_example_2">XML encodings don't work</string>
I use hebrew(RTL language) in strings.xml.
I have manually searched the string.xml for this char: ‘
than I added the escape char \ infront of it (now it looks like \’ ) and still got the same error!
I searched again for the char ‘ and I replaced the char ‘ with \'(eng writing) , since it shows a right to left it looks like that ‘\ in the strings.xml !!
Use this regex
(?<!\\)' for searching an unescaped apostrophe.
It finds an apostrophe that not preceded by a backslash.
You may be able to use unicode equivalent both apostrophe and other characters which are not supported in xml string. Apostrophe’s equivalent is “\u0027” .
1. for error: unescaped apostrophe in string
what I found is that AAPT2 tool points to wrong row in xml, sometimes.
So you should correct whole strings.xml file
In Android Studio, in problem file use :
Then write in first field \’ (or \&,>,\<,\”)
in second put ‘(or &,>,<,”)
then replace each if needed.(or “reptlace all” in case with ‘)
Then in first field again put ‘(or &,>,<,”)
and in second write \’
then replace each if needed.(or “replace all” in case with ‘)
2. for other problematic symbols
I use to comment each next half part +rebuild
until i won’t find the wrong sign.
E.g. an escaped word “\update” unexpectedly drops such error 🙂
The best answer of simply escaping the
\' works but I do not like the solution because when using replace all with
\', it only works once. The second time you’ll be left with
