android - Grid view crashe the app on scrolling on too many images -

in project uses custom adapter grid view , when grid view load many items contain images on scrolling activity crashes , reloads again. had resource problem on loading image solved of @raghunandan error out of memmory. cause think loadfull size images.

public class myadapter extends arrayadapter<structurecase> {      private layoutinflater minflater           = null;     public context         context;     public class           distinationactivity = null;      public myadapter(context context, int textviewresourceid, list<structurecase> objects) {         super(context, textviewresourceid, objects);         minflater = layoutinflater.from(context);        // minflater = (layoutinflater)g.currentactivity.getsystemservice(context.layout_inflater_service);      }      public static class viewholder {        public imageview gem_img   = null;        public textview  gem_name   = null;     }      @override     public view getview(int position, view convertview, viewgroup parent) {         final viewholder viewholder;         final view v;          final structurecase item = getitem(position);          if (convertview == null) {              convertview = this.minflater.inflate(r.layout.my_grid_list,  null);             //minflater = (layoutinflater)g.currentactivity.getsystemservice(context.layout_inflater_service);             convertview = minflater.inflate(r.layout.my_grid_list, parent, false);             viewholder = new viewholder();             convertview.settag(viewholder);              viewholder.gem_img = (imageview) convertview.findviewbyid(r.id.imageview_mygrid_list);             viewholder.gem_name = (textview) convertview.findviewbyid(r.id.textview_mygrid_list);              viewholder.gem_name.settypeface(g.typefaceprs);          } else {            viewholder = (viewholder) convertview.gettag();         }          int temp = 0;          viewholder.gem_name.settext(item.g_name);     int id = g.currentactivity.getresources().getidentifier(item.g_image, "drawable", g.currentactivity.getpackagename());         drawable drawable = g.currentactivity.getresources().getdrawable(id);         if(drawable != null){         viewholder.gem_img.setimagedrawable(drawable);         }else{             viewholder.gem_img.setimageresource(r.drawable.almas);          }            //viewholder.newsthumb.setimageresource(temp);          viewholder.gem_img.setonclicklistener(new onclicklistener() {             @override             public void onclick(view v) {             }         });          return convertview;     }      @override     public long getitemid(int position) {         return position;     } 

use code in getview method while setting bitmap in imageview.

private bitmap decodeuri(uri selectedimage) throws filenotfoundexception  {             bitmapfactory.options o = new bitmapfactory.options();             o.injustdecodebounds = true;             bitmapfactory.decodestream(                     getcontentresolver().openinputstream(selectedimage), null, o);              final int required_size = 800;              int width_tmp = o.outwidth, height_tmp = o.outheight;             int scale = 1;             while (true) {                 if (width_tmp / 2 < required_size || height_tmp / 2 < required_size)                  {                     break;                 }                 width_tmp /= 2;                 height_tmp /= 2;                 scale *= 2;             }              bitmapfactory.options o2 = new bitmapfactory.options();             o2.insamplesize = scale;`enter code here`             return bitmapfactory.decodestream(                     getcontentresolver().openinputstream(selectedimage), null, o2);         }
