Android icon error -

i copied code tutorial site because trying learn it. getting error at

package com.android.test; import android.r; import android.app.activity; import android.graphics.bitmap; import android.graphics.bitmapfactory; import android.graphics.matrix; import android.graphics.drawable.bitmapdrawable; import android.os.bundle; import android.view.view; import android.widget.adapterview; import android.widget.arrayadapter; import android.widget.imageview; import android.widget.seekbar; import android.widget.spinner; import android.view.viewgroup.layoutparams; import android.widget.linearlayout; import android.widget.imageview.scaletype; public class rotate extends activity {      @override      public void oncreate(bundle savedinstancestate) {          super.oncreate(savedinstancestate);          linearlayout linearlayout = new linearlayout(this);     bitmap bitmap = bitmapfactory.decoderesource(getresources(), r.drawable.icon); 

on last line, error ".icon" written. says, "icon cannot resolved or not field."

int width = bitmap.getwidth(); int height = bitmap.getheight();

   matrix matrix = new matrix();    matrix.postrotate(90);     bitmap rotatedbitmap = bitmap.createbitmap(bitmap, 0, 0, 

width, height, matrix, true); bitmapdrawable bmd = new bitmapdrawable(rotatedbitmap);

   imageview imageview = new imageview(this);    imageview.setimagedrawable(bmd);    imageview.setscaletype(scaletype.center);     linearlayout.addview(imageview, new linearlayout.layoutparams(      layoutparams.fill_parent, layoutparams.fill_parent));    setcontentview(linearlayout);      }  } 

in import statements, have

import android.r; 

that means it'll in android.r.drawable.icon, rathern r.drawable.icon. android.r contains ids assets sdk. access own assets, need remove using statement, or manually write com.your.package.name.r.drawable.icon
