This could be a case of the IDE becoming too strict   The idea is sound  in general you should specify the order of substitution variables so that should you add resources for another language  your java code will not need to be changed  However there are two issues with this   Firstly  a string such as   You will need   5G  s   to be used as You will need 2 1200 mg will have the order the same in any language as that amount of mass is always represented in that order scientifically   The second is that if you put the order of variables in what ever language your default resources are specified in  eg English  then you only need to specify the positions in the resource strings for languages the use a different order to your default language   The good news is that this is simple to fix  Even though there is no need to specify the positions  and the IDE is being overly strict  just specify them anyway  For the example above use      You will need  1  5G  2 s

The Android Asset Packaging Tool  aapt  has become very strict in its latest release and is now used for all Android versions  The aapt-error you re getting is generated because it no longer allows non-positional format specifiers   Here are a few ideas how you can include the  -symbol in your resource strings   If you don t need any format specifiers or substitutions in your string you can simply make use of the formatted attribute and set it to false    lt string formatted  false  gt  a    a    2 a lt  string gt    In this case the string is not used as a format string for the Formatter so you don t have to escape your  -symbols  The resulting string is   a    a    2 a    If you omit the formatted  false  attribute  the string is used as a format string and you have to escape the  -symbols  This is correctly done with double-     lt string gt   a     a    2  a lt  string gt    Now aapt gives you no errors but depending on how you use it  the resulting string can be    a     a    2  a  if a Formatter is invoked without any format arguments   Resources res   context getResources     String s1   res getString R string str      s1       a     a    2  a   String s2   res getString R string str  null      s2      a    a    2 a    Without any xml and code it is difficult to say what exactly your problem is but hopefully this helps you understand the mechanisms a little better
