I have a custom task in my build.gradle which generates some string resources:
android.defaultConfig.resValue "string", "my_string", "Some Value"
This all works fine: the strings appear correctly in generated.xml and are accessible via getResources().getString(R.id.my_string)
in the application code.
It doesn't work when one of the strings contains a %
symbol. It gives this error:
Error:(1) Multiple substitutions specified in non-positional format; did you mean to add the formatted="false" attribute?
I understand from Android XML Percent Symbol that one would normally work around this, for a string resource in strings.xml , by supplying the extra formatted="false"
attribute as follows:
<string formatted="false">My string with a % symbol</string>
How can I include the formatted="false"
attribute when the string is generated using resValue
in the build script?
(I have also tried escaping with double-% as suggested, but that results in %%
appearing in the final string.)
I solved it by replacing the raw %
symbol with a double-escaped unicode value at string generation time in the gradle task.
android.defaultConfig.resValue "string", "my_string", \
"String with a % symbol".replaceAll("%","\\\\u0025")
You can use % in xml
try this format \\%% in your xml
<string name="foo">percent symbol 50\%% </string>
