因此，我创建了一个应用程序，其中有5个活动，其中有5个独立的soundBoards，其中有5个独立的soundPools。我还在每个活动中使用导航抽屉。当我运行应用程序时，它可以打开前两个活动，但每当我打电话给第三个时打开该应用程序停止工作。在内存监视器上，内存使用量达到64MB，然后崩溃。它只是模拟器被限制为64MB，并且它可以在手机上正常工作，或者是否有内存泄漏？当我切换到另一个活动，然后onStart重新打开时，还是不需要时，是否需要调用onStop？如果我做了这个项目我该怎么做？当我打开另一个活动时，应用程序崩溃
这里查看我的崩溃日志的链接：https://www.dropbox.com/s/x5obsexzgi2ofaa/crashlog2.docx?dl=0

如果您需要任何更多的代码，让我知道。我不确定问题是什么。
你可以发布'MrSmith'类的XML吗？ – 2015-03-31 09:56:53
@Zygotelnit检查我的编辑问题 – 2015-03-31 10:01:22
你能告诉我什么是在“MrSmith”类的XML文件的第85行吗？ – 2015-03-31 10:04:27
