javascript – Phonegap 3.0媒体API – 破碎？

我正在尝试播放Phonegap 3.0中的音频文件,在Windows上运行,安卓平台,在Eclipse中进行调试.

我试图升级我的工作,没有错误,应用程序到3.0,并有很多问题.

例如,当我播放声音时,它会播放,然后我从MediaRecorder API中找到一个不存在的tmp文件的文件重命名错误？但是,我没有调用任何重命名或记录.

>看来,一旦成功调用播放声音命令,就会调用录音API. 3.0如何运作必定存在一些重大错误.

这是日志.正如您所看到的那样,声音文件播放正常,然后由于某种原因调用MediaRecorder并尝试重命名不存在的tmp文件.请记住,我的代码在升级过程中没有改变,因此没有任何理由可以解决这些错误.我正在关注3.0文档中的媒体播放API.我也得到新的线程警告错误.我正在播放的声音文件是100KB以下的短片.

使用CLI工具添加了插件,我已将功能代码添加到config.xml文件中,并且我已将权限添加到清单文件中.我已经读过其他人有这个问题,似乎没有任何解决方案.

解决方法:

我感觉到你的痛苦.我花了很多时间在我的PhoneGap应用程序中将音频和视频播放工作在iOS和ANDROID上工作……当我开始工作时,我几乎要流泪了.一旦我站到了另一边,我尽我所能将核心功能提取到一组独立的文件中,以便将来重新访问/重用.如果您愿意,请随意查看并测试：

顺便说一句 – 这里的功能确实使用PhoneGap Media API来提供音频.如果这有帮助,请告诉我.
