【问题描述】：
我制作了一个关于直播电视流的应用。它运行良好，但几分钟后它会自动停止。我点击屏幕，但它不起作用。我已经展示了我的代码。如果有什么要添加或删除的，请告诉我。我已经尝试过但失败了。

【问题讨论】：
-
请注意，带有“请帮助我”和“请编辑我的代码并为我修复它”的问题通常在这里被严重低估，所以当我看到一个上面有 +2 的问题时，我的直觉告诉我知道 OP 认识的人都在支持它。如果您知道有人这样做，请告诉他们不要再这样做了 - 我见过有大量以欺诈手段获得声誉的人，一旦被发现，他们的分数会在一夜之间减半。

因此，这个问题需要进行一些编辑才能使其成为主题。 “不起作用”是什么意思？你做了什么调试？我们可以看到您的崩溃日志被编辑到问题中吗？您从自己查看堆栈跟踪中学到了什么？
-
要让您的问题得到解答，您应该尽可能清楚和有用。第一步是通过更新来澄清 cmets 中提出的问题。
