我正在使用Java制作简单的Android游戏。我每20-40秒就注意到一些令人讨厌的滞后。首先，我认为它们是由垃圾收集器引起的，但是当我检查我的LogCat时，我发现在游戏滞后时没有垃圾收集。 每当游戏开始滞后时我就会记录日志，并且几乎每次都会看到这个日志条目：
W / qdhwcomposer（209）：读取vsync的延迟时间过长：耗时47 ms
正如它所说，有一个延迟（通常> 45ms），我认为这是我注意到的延迟。 有人知道这个问题或如何避免这些延误吗？
这是游戏滞后时LogCat的两个片段：

我在三星Galaxy S4（GT-I9505）btw上用Android 4.3测试了它。
