eclipse - Met Strange situation In Exporting&Running Android project -

i have got strange situation when working on project.i have run application once. changed "android:margin" properties xml files. problem came. ran project , crashed. log says comes resource not found exception. next tried export failed export. i'll post log , error dialog below.

what have done: reinstalled such eclipse,adt , sdk. not work @ all. i'm absolutely sure resource exists , stays in right position.**

all useful information needed.

ps: resource file not found activity layout xml file--my intro activity , i've found resource id in r file.

ps: friends use same code me.they don't have problem.

here's layout xml file:

<?xml version="1.0" encoding="utf-8"?> <framelayout xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/fl_base_activity"     android:layout_width="match_parent"     android:layout_height="match_parent" >      <imageview         android:id="@+id/iv_base_wallpaper"         android:layout_width="match_parent"         android:layout_height="match_parent"         android:scaletype="centercrop" />      <imageview         android:layout_width="match_parent"         android:layout_height="match_parent"         android:src="@color/trans_cc" />  </framelayout> 

try re-building project , if doesn't work , delete 'build' , 'gen' folders of project(you can take backup elsewhere remove them project folder) , try running again.

let me know if works.....
