I want to load a single line text file in to edittext1 but it not
probably loading as it was work in pervious app [api 29 ] .
 Also May be one more thing
var
  txtContent: string;  
begin
txtContent:= TextFileManager1.LoadFromAssets('nm.txt');

     edittext1.text:=txtContent;
may not working.
 Kindly suggest solution.

This process required some modification of the relevant demo.
Regarding this process, let's first modify the AppOpenFileDialogDemo1
demo a bit.
Let's add the jEditText1 component to the demo. Then, let's update the
jOpenDialog1FileSelected method as follows.
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i procedure
TAndroidModule1.jOpenDialog1FileSelected(Sender: TObject; path:
string; fileName: string);var  Stream:TFileStream; 
filemergestring:string;begin   if IsRuntimePermissionGranted('android.
permission.WRITE_EXTERNAL_STORAGE') then   begin      if Pos('.txt',
filename) > 0 then      begin       
stream:=TFileStream.Create(path+'/' + fileName,fmOpenRead or
 fmShareDenyNone);  stream.Position:=0;       
setLength(filemergestring,stream.Size);       
stream.ReadBuffer(pointer(filemergestring)^, stream.Size);       
stream.Free;        jEditText1.Text:=filemergestring;      end; 
 end;end;
