Simply I tried to create display with size (1280, 720). But, actual display was created with size (2094, 1080) as the attached png.
Is any option or flag required?
On Android, you can generally only get a display the size of the physical screen.
There may have been a development with ALLEGRO_FRAMELESS and ALLEGRO_FULLSCREEN_WINDOW, which is preferred to ALLEGRO_FULLSCREEN. You should probably be happy with what you get, and use a simple transform to draw everything.
Some links ;

https://liballeg.org/a5docs/trunk/display.html#al_set_new_display_flags
ALLEGRO_TRANSFORM t; al_identity_transform(&t); al_get_current_transform(&t); al_scale_transform(&t , (float)al_get_display_width(display)/MYWIDTH , (float)al_get_display_height(display)/MYHEIGHT);
Then in your drawing code, you use the transform to scale your graphics up to the screen dimensions.
1 if (redraw) {
2 al_clear_to_color(al_map_rgb(255,255,255));
3 ALLEGRO_TRANSFORM old;
4 al_get_view_transform(&old);
5 al_use_transform(&t);
6 /// Draw normally here
7 al_draw_my_cool_stuff();
8 al_flip_display();
9 al_use_transform(&old);
10 redraw = false;
11 }
12 do {
13 ALLEGRO_EVENT ev;
14 al_wait_for_event(queue , &ev);
15 if (ev.type == ALLEGRO_EVENT_WHATEVER) {
16 DoStuff();
17 }
18 } while (!al_is_event_queue_empty(queue));
