Does android cache an application preference?
<p>I would like to know does Android caches an application preference?</p>

<p>I have an activity running. 
And then I go to Setting->Manage Application->find my application-> clear data.</p>

<p>But from my activity, the value of a preference in my application stays the same, despite I clear it thru the above step.</p>

<p>But then when I power off and then power on the phone, that seems to clear it.</p>

<p>My question is does android some how cache an application preference?</p>

<p>Thank you.</p>
