i have 3 Activity . say a ,b, c . i have loaded obj model in "a" Activity then when i click on button it open "b" Activity and take image and open c Activity . In "c" Activity i want display same model which i loaded in "A" Activity. is any way so that i can save the time   and use same loaded model instead of loading again

i am trying to load large obj file (12mb) but app is crashing . but same code is working to load obj file having 1 mb

My code is

File sdRoot = Environment.getExternalStorageDirectory();
            File file = new File(sdRoot+ "/WatchApp/12345.obj");
            InputStream inputStream = null;
            try {
               inputStream = new FileInputStream(file);
            } catch (FileNotFoundException e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();
            }
            cube = Object3D.mergeAll(Loader.loadOBJ(inputStream, null, 5f));

cube.build();

            world.addObject(cube);
