<li>Because of the 512MB size restriction on downloadable packages, the following 32-bit items are not in the 32-bit NDK download packages. Instead, they reside in the 64-bit ones:</li>
<ul>
<li>Android-L headers</li>
<li>GCC 4.9</li>
</ul>
<li>Currently, the only Renderscript support provided by the NDK is for 32-bit Renderscript with Android 4.4 (API level 19). You cannot build HelloComputeNDK (the only Renderscript sample) with any other combination of Renderscript (32- or 64-bit) and Android version.</li>
<li>To compile native-codec, you must use a 64-bit NDK package, which is where all the Android-L headers are located. </li>
</ul>
