Delphi Seatle can link Delphi project with Static library files(*.a):
1.at Delphi IDE, Add the "*.a" file Path to Library Path:
a. Tools Menu
b.Options
c.Delphi Options -> Library -> Selected platform "Android"
d.Library path -> Add the path of *.a file
e.OK
2.Here is an unit I made: utLibTest.pas is linked with libtest.a
unit utLibTest; {$link libtest.a} interface const libproj='libtest.a'; (* procedure prototypes *) //將lon,2Pi周期內轉換到-pi到pi之間 function adjlon(lon:Double):double;cdecl; //將度分秒字符串轉換成弧度,iss為字符串,rss為結束字符指針 function dmstor(iss:PByte; var rss:PByte):double;cdecl; implementation function adjlon; external libproj; function dmstor; external libproj; end.
