  Android NDK, Revision 5c</a> <em>(June 2011)</em>

  <div class="toggleme">

    <p>This release of the NDK does not include any new features compared to r5b. The r5c release

    addresses the following problems in the r5b release:</p>

    <dl>

      <dt>Important bug fixes:</dt>

      <dd>

        <ul>

          <li><code>ndk-build</code>: Fixed a rare bug that appeared when trying to perform parallel

          builds of debuggable projects.</li>

          <li>Fixed a typo that prevented <code>LOCAL_WHOLE_STATIC_LIBRARIES</code> to work

          correctly with the new toolchain and added documentation for this in

          <code>docs/ANDROID-MK.html</code>.</li>

          <li>Fixed a bug where code linked against <code>gnustl_static</code> crashed when run on

          platform releases older than API level 8 (Android 2.2).</li>

          <li><code>ndk-gdb</code>: Fixed a bug that caused a segmentation fault when debugging Android 3.0

          or newer devices.</li>

          <li><code>&lt;android/input.h&gt;</code>: Two functions that were introduced in API level

          9 (Android 2.3) were incorrect and are fixed. While this breaks the source API, the

          binary interface to the system is unchanged. The incorrect functions were missing a

          <code>history_index</code> parameter, and the correct definitions are shown below:

<pre>

float AMotionEvent_getHistoricalRawX(const AInputEvent* motion_event,

                                           size_t pointer_index,

                                           size_t history_index);

float AMotionEvent_getHistoricalRawY(const AInputEvent* motion_event,

                                           size_t pointer_index,

                                           size_t history_index);

</pre>

          </li>

          <li>Updated the C library ARM binary for API level 9 (Android 2.3) to correctly expose at

          link time new functions that were added in that API level (for example,

          <code>pthread_rwlock_init</code>).</li>

        </ul>

      </dd>

      <dt>Minor improvements and fixes:</dt>

      <dd>

        <ul>

          <li>Object files are now always linked in the order they appear in

          <code>LOCAL_SRC_FILES</code>. This was not the case previously because the files were

          grouped by source extensions instead.</li>

          <li>When <code>import-module</code> fails, it now prints the list of directories that

          were searched. This is useful to check that the <code>NDK_MODULE_PATH</code> definition

          used by the build system is correct.</li>

          <li>When <code>import-module</code> succeeds, it now prints the directory where the

          module was found to the log (visible with <code>NDK_LOG=1</code>).</li>

          <li>Increased the build speed of debuggable applications when there is a very large number

          of include directories in the project.</li>

          <li><code>ndk-gdb</code>: Better detection of <code>adb shell</code> failures and improved

          error messages.</li>

          <li><code>&lt;pthread.h&gt;</code>: Fixed the definition of

          <code>PTHREAD_RWLOCK_INITIALIZER</code> for API level 9 (Android 2.3) and higher.</li>

          <li>Fixed an issue where a module could import itself, resulting in an infinite loop in

          GNU Make.</li>

          <li>Fixed a bug that caused the build to fail if <code>LOCAL_ARM_NEON</code> was set to

          true (typo in <code>build/core/build-binary.mk</code>).</li>

          <li>Fixed a bug that prevented the compilation of </code>.s</code> assembly files

          (<code>.S</code> files were okay).</li>

        </ul>

      </dd>
