Answer 1

For these kind pf task you can use the Intent class which is represented in Delphi by the JIntent interface.

Try these samples

Open a URL

uses
  Androidapi.JNI.GraphicsContentViewText,
  FMX.Helpers.Android;


procedure TForm3.Button1Click(Sender: TObject);
var
  Intent: JIntent;
begin
  Intent := TJIntent.Create;
  Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);
  Intent.setData(StrToJURI('http://www.google.com'));
  SharedActivity.startActivity(Intent);
end;

Open a PDF File

uses
  Androidapi.JNI.GraphicsContentViewText,
  Androidapi.JNI.JavaTypes,
  FMX.Helpers.Android;


procedure TForm3.Button1Click(Sender: TObject);
var
  Intent: JIntent;
begin
  Intent := TJIntent.Create;
  Intent.setAction(TJIntent.JavaClass.ACTION_VIEW);
  Intent.setDataAndType(StrToJURI('filepath'),  StringToJString('application/pdf'));
  SharedActivity.startActivity(Intent);
end;
