我已完成下载并导入 android 演示项目到 Eclipse 但无法构建：
From the IDE, just open the project file and compile. From command line, see below:
=== Windows =
devenv -build "Debug" libjingle.sln
devenv -build "Release" libjingle.sln

我已经从命令行尝试了这个 Build Eclipse Java Project，但它仍然没有编译。因为我仍然在 eclipse 中看到这些错误：
I420Frame cannot be resolved to a type
IceCandidate cannot be resolved to a type
MediaConstraints cannot be resolved to a type
PeerConnection cannot be resolved to a type
MediaStream cannot be resolved to a type
iceServers cannot be resolved or is not a field
StatsReport cannot be resolved to a type
SessionDescription cannot be resolved
SdpObserver cannot be resolved to a type
The import org.webrtc cannot be resolved AppRTCClient.java /AppRTCDemoActivity/src/org/appspot/apprtc
请帮帮我。
提前致谢。
