Using the current Navigation SDK version 6.3.0 I see the error:
Error APT2000 : multiple substitutions specified in non-positional format; did you mean to add the formatted="false" attribute?.
I could track it down to the following values.xml entries:
<string name="HEIGHT_FEET_INCHES_ABBREVIATED" msgid="8966636302039617408">"<xliff:g id="FEET">%d</xliff:g> ಅಡಿ <xliff:g id="INCHES">%d</xliff:g> ಇಂಚು"</string>
<string name="HEIGHT_FEET_INCHES_LONGFORM" msgid="8637363475448752754">"<xliff:g id="FEET">%d</xliff:g> ಅಡಿ <xliff:g id="INCHES">%d</xliff:g> ಇಂಚುಗಳು"</string>
The fix would be to add the parameter positions for %d.
