【问题描述】：

我正在尝试测试 Android Gstreamer。所以我安装并配置了路径SDK，得到了tutorial source，修改教程的Android.mk中的路径，并在android-tutorial-1/jni处进行ndk-build。但我得到了

标签： android gstreamer

【解决方案1】：

您使用的那个教程实际上并不是来自 GStreamer，而是来自第三方，而且现在已经很老了。我无法让它与 Android Studio 一起工作，只有 Eclipse。如果您想使用最新的 Android GStreamer，我建议您查看this Github project。

它应该可以直接与 GStreamer SDK 1.8.0 或更高版本一起使用。您需要的唯一更改是在 build.gradle 文件中，在 getNdkCommandLine(ndkRoot, target) 方法中将 gstRoot 变量设置为 GStreamer SDK 的路径。

【讨论】：

谢谢你告诉我那个来源。我尝试使用该源，但实际上我不知道如何使用它......我用 Eclipse 导入它并修改布局文件夹中 main.xml 文件上的match_parent -> fill_parent。之后，将版本从 2.1 更改为 4.4.2，并加上<uses-sdk android:minSdkVersion="19" />。最后 src 文件夹中没有文件，我有一个 No Launcher activity found! The Launch will only sync the application package on the device! 错误。
或者我应该使用 Android Studio 作为那个源？？
这些源代码是为 Android Studio 和 Gradle 构建系统制作的，Eclipse 不使用它们。您不应该再使用 Eclipse，而应该只使用 Android Studio。如果您需要使用现有项目，我建议将其迁移到 Android Studio，这将有助于解决未来的其他问题 :)
我只需要在任何工具（Eclipse 或 Android Studio）上运行测试源。好吧..我尝试使用您链接的来源。但它看起来很奇怪，所以当我打开或导入它时我无法使用它。还有其他我应该知道的使用方法吗？？
下载我链接的完整源代码，并将其解压缩到某个地方。打开 Android Studio 并转到 File->Open，然后选择名为 'android' 的文件夹（在此文件夹内应该是一个 'app' 文件夹和一个 'gradle' 文件夹，以及一个名为 'build.gradle' 的文件）。然后点击确定，项目应该可以正常打开

见gstreamer-devel，你可能错过了android更新

你能告诉我更多细节吗？？
