i am new to android application development. i have run hello world program only.
now i want to run some sample code.
when i try to run them i got this error in new dialog box:
"Could not write file: C:\Program Files (x86)\Android\android-sdk\samples\android-15\SoftKeyboard.project.
C:\Program Files (x86)\Android\android-sdk\samples\android-15\SoftKeyboard.project (Access is denied)"

i am trying to run 'softkeyboard' sample .

i did this: new android project>create project from another source>
and the path i have given is C:\Program Files (x86)\Android\android-sdk\samples\android-15\SoftKeyboard

why is this error coming?
