Hi Carsten,I am using a raw edje object. Follow your advise, i use evas_object_image_add and evas_object_image_file_set can display different images in my GUI. But when the number/size of image is large, it will consume a lot of memory, is there any way to reduce the memory consumption?
Besides, it there any way to play mp3 and mp4 file ? Please advise, many thanks.
