delphi XE7 firemonkey android shared object / library to be dynamically loaded - template

Question

Is there a template to create a .so file that can be loaded by another delphi ape file - I have tried starting a blank fire monkey project and changing program to library and build it but the .so file that it produces won't load with dlopen within another delphi project. I have read that in other development environments there is a islibrary setting. I guess more to the point is there an example .so library built with fire monkey - I have found the bare bones link without fire monkey but it uses just jni not androidapi.jni - thanks

Answer 1

the following codes may be useful.

//-- Code for libMylib.so (MyLib.dproj) --- 

    library MyLib; 
//    uses  SysUtils;


    function GetSum(a, b: integer ) : integer; cdecl; 
    begin 
      Result := a + b; 
    end;

    exports

    GetSum        name 'GetSum'; 

    begin 
    end. 

    //-- Code for using libMylib.so (TestMyLib.dproj) --- 

    var 
    DocDir, LibFN: string; 
    GetSum: function(a, b: integer ) : integer; cdecl; 
    hLib: HMODULE; 

    begin 
      DocDir := IncludeTrailingPathDelimiter(System.IOUtils.TPath.GetLibrary`enter code here`Path);
      LibFN:=DocDir + 'libMyLib.so';
      hLib := LoadLibrary(LibFN); //ERROR (Segmentation fault (11)) 
      if hLib<>0 then 
      begin 
        GetSum := GetProcAddress(hLib, 'GetSum');//It works
        ShowMessage(IntToStr(GetSum(3, 8)));//It works 
      end; 
    end; 

P.S: you must add compiled libMyLib.so file to Deployment of TestMyLib.dproj.

P.S2: it gives an error while executing "LoadLibrary", but it Works.

I couldn't find a solution. Probably it is related with compiler/linker options of MyLib.dproj. Because when I test another '.so' file which is compiled with C++, no problem occurs while calling LoadLibrary.
