我要使用 ijkplayergithub链接 https://github.com/bbcallen/ijkplayer。我下载了这个，然后通过“文件”>“导入”>“常规”>“现有项目到工作区”将其导入到 eclipse 中。之后我有三个项目：
1.ijkmediaplayer ( library )
2.ijkmediawidget ( VideoView-like interface )
3.ijkmediademo ( Demo project )
当我运行 ijkmediademo 时，发生错误并且程序崩溃。我收到这些错误行：

程序似乎找不到 IjkMediaPlayer 类中设置的一些库：
public static void loadLibrariesOnce(IjkLibLoader libLoader) {
synchronized (IjkMediaPlayer.class) {
if (!mIsLibLoaded) {
libLoader.loadLibrary("stlport_shared");
libLoader.loadLibrary("ijkffmpeg");
libLoader.loadLibrary("ijkutil");
libLoader.loadLibrary("ijkadk");
libLoader.loadLibrary("ijksdl");
libLoader.loadLibrary("ijkplayer");
mIsLibLoaded = true;
}
}
}
这些库是什么？
这些图书馆在哪里？ （我在项目中找不到它们）
如何解决这个问题？
看来您还没有构建所需的库 - 您必须自己构建。
按照标题下的说明进行操作构建Android在页面上ijkplayer github 链接 https://github.com/bbcallen/ijkplayer
成功构建过程后，您将获得几个库文件（libijkffmpeg、libijkutil、libijkadk、libijksdl、libijkplayer）将自动放入ijkmediaplayer/libs folder.
我已经成功构建了伊克播放器下的图书馆虚拟盒 Ubuntu 12.04。
你必须安装安卓NDK.
