Question

我正在做一个从服务中获取数据并在图表中表示的应用程序。 App运行正常，但在logcat中出现了很多GC_FOR_ALLOC消息。

无论如何都要减少这些消息？任何功能还是什么？

这是logcat：

GC_FOR_ALLOC只是意味着没有足够的内存来完成分配任务，因此需要通过GC分配更多的空间。

当Android启动时，它从一个小堆开始，随着应用程序的增长和消耗内存而增长。在增加内存之前，运行GC_FOR_ALLOC，这是标准的预期行为。这不一定是因为你的应用程序占用了太多内存。

从您的logcat输出中，似乎没有任何奇怪的事情发生。如果要关闭这些消息，它们的日志级别为DEBUG。任何日志级别都高于此值，您将看不到它们。

减少内存警告并改善内存管理
