Android downloading
<p>I downloaded the Android SDK installer file and when i installed it, it launches the SDK manager which then installs many things. i have the following doubts</p>

<ol>
<li>Are the things which the Android SDK manager asks us for installing essential because i have a very slow Internet connection and the file size under SDK manager is too high.</li>
<li>Secondly if files under SDK manager can be downloaded on a different computer with high speed Internet connection and then can be copied to my computer ? Is this possible?</li>
</ol>
