AllegroActivity::onResume() isn't called.

[YongJin-Cho]

When pausing and resuming, logcat doesn't give "onResume".
And app crashed because of no responding.

[YongJin-Cho]

after resuming, touch input doesn't work and makes crash. the below is the code.

#include <allegro5/allegro5.h>

int main(int argc, char **argv) {
al_init();
al_install_touch_input();

auto display = al_create_display(0, 0);
auto queue = al_create_event_queue();
auto timer = al_create_timer(1 / 60.0);
auto redraw = true;
al_register_event_source(queue, al_get_display_event_source(display));
al_register_event_source(queue, al_get_timer_event_source(timer));
al_start_timer(timer);

al_register_event_source(queue, al_get_touch_input_event_source());

ALLEGRO_DEBUG_CHANNEL("app");

while (true) {
    if (redraw) {
        al_clear_to_color(al_map_rgb_f(1, al_get_time() - (int)(al_get_time()), 0));
        al_flip_display();
        redraw = false;
    }
    ALLEGRO_EVENT event;
    al_wait_for_event(queue, &event);
    if (event.type == ALLEGRO_EVENT_TIMER) {
        redraw = true;
    }
    else {
        redraw = true;
        ALLEGRO_DEBUG("event: %d\n", event.type);
    }
}
return 0;

}

the below is log.
