详细:这个问题主要出现在android 4.3当我们再次准备并开始时第一次发生异常媒体记录器。这个逻辑在 4.0 中成功工作..我不明白为什么会出现这种异常。

Answer 1

似乎如果设备决定休眠，而 GC 决定运行，那么就会发生这种情况。

见下文:

Sometimes (very rarely) the System will decide to Sleep in the middleof the GC run.

If the sleep time was long - over 10 seconds, the concurrent.timeout exception will be thrown.
