我检查了此问题，但找不到任何解决方案。
我正在Android中实现RTSP播放器，并且为此使用了Easy Player。使用此播放器，我已经实现了我的演示应用程序并输入了rtsp:// URL。
问题：当我在库示例代码中输入相同的URL时，它可以正常工作，但是当我尝试使用Demo应用程序时，应用程序会随着stackTrace崩溃。

我尝试了几乎所有事情，但找不到解决方案。如果我做错了什么并为我提供解决方案，请纠正我。
预先感谢。
我发现了我的错误，在Easy Player中，为每个软件包名称生成一个唯一的密钥，在我的情况下，键是不正确的。我不知道为什么它会给无效的键带来内存泄漏错误！更换包装名称并解决了此问题。奇怪但真实。
