<p>With NDK revision 9 and higher, the release packages have been split to reduce download size.

  The first download for each platform contains the default NDK toolchain. The additional download

  The first download for each platform contains the default NDK toolchain. The second download

  contains legacy NDK toolchains for that platform, which is only required if you are not using

  the current, recommended toolchain for your NDK builds.</p>

<p>The following sections provide information about releases of the NDK.</p>

        <dt>Important notes:</dt>

     <dd>

     <ul>

      <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>

     </dd>

     <dt>Important bug fixes:</dt>

     <dd>
