You'll need this unit:

https://github.com/DelphiWorlds/KastriFree/blob/master/API/DW.Androidapi.JNI.FileProvider.pas

for this code:

uses
  Androidapi.JNI.JavaTypes, Androidapi.JNI.Net, Androidapi.JNI.GraphicsContentViewText, Androidapi.Helpers;

procedure OpenPDF(const AFileName: string);
var
  LIntent: JIntent;
  LAuthority: JString;
  LUri: Jnet_Uri;
begin
  LAuthority := StringToJString(JStringToString(TAndroidHelper.Context.getApplicationContext.getPackageName) + '.fileprovider');
  LUri := TJFileProvider.JavaClass.getUriForFile(TAndroidHelper.Context, LAuthority, TJFile.JavaClass.init(StringToJString(AFileName)));
  LIntent := TJIntent.JavaClass.init(TJIntent.JavaClass.ACTION_VIEW);
  LIntent.setDataAndType(LUri, StringToJString('application/pdf'));
  LIntent.setFlags(TJIntent.JavaClass.FLAG_GRANT_READ_URI_PERMISSION);
  TAndroidHelper.Activity.startActivity(LIntent);
end;
