i've application uploading image choosen gallery. before upload show selected image in imageview , let user choose image or upload current. downscale image if widht or height bigger 1000 i'm able scale bitmap in imageview. me or give me suggestion? here code, appreciated, in advance.

    protected void onactivityresult(int requestcode, int resultcode, intent data) {      if (requestcode == 1 && resultcode == result_ok) {         //bitmap photo = (bitmap) data.getdata().getpath();         //uri imagename=data.getdata();         uri selectedimageuri = data.getdata();         imagepath = getpath(selectedimageuri);         bitmap bitmap=bitmapfactory.decodefile(imagepath);         int width = bitmap.getwidth();         int height = bitmap.getheight();          if(width>=1000 || height >= 1000){             width = width/3;             height = height/3;             bitmap = bitmap.createscaledbitmap(bitmap, width, height, false);             }         imageview.setimagebitmap(bitmap);         uploadbutton.setvisibility(view.visible);      } } public string getpath(uri uri) {     string[] projection = { mediastore.images.media.data };

you can decode image bitmap using 1 of static methods bitmapfactory class, whether using existing fileinputstream opening or passing in file path.

following can use createscaledbitmap method resize down, , use compress put outputstream.
