这是我的代码:

我希望任何人都能看到这个问题,并能帮助我解决这个问题

 android:largeHeap="true"
在你的android清单中,希望这能解决你的问题。

请更详细地说明这个问题到底发生在哪里对不起!当我点击btSetHuidigeLocatie按钮时,Android Studio在日志中给出了这个问题。使用调试器继续执行,直到按钮按下后出现这个问题。这就是问题所在。它将帮助我们找到问题。stacktrace不完整,或者说stacktrace行中没有任何一行提到您的类?我们需要知道错误发生在您编写的文件的哪一行。很可能您的应用程序正在某处泄漏内存,特别是考虑到当您遵循错误的largeHeap=true建议时,这种情况仍在发生。这里的任何人都不太可能仅仅通过查看源代码就发现内存泄漏。了解如何在上监视内存使用,并在逐步浏览应用程序时这样做,以缩小泄漏发生的范围。可能在一些设备上工作,但不是最佳样式,不是吗?大多数应用程序不应该需要这样做,而是应该专注于减少总体内存使用以提高性能。启用此选项也不能保证可用内存的固定增长,因为某些设备受其总可用内存的限制。我也添加了此选项,但没有帮助。是的,这不是解决OOM的好方法,但这是一个非常快速的选项,否则,您必须减少设备中的内存消耗。我觉得这可以作为评论,而不是回答。因为它是一个非常可怕的黑客,并可以促进坏的实践。@ DeBoMiTrayi我同意你,这是不好的做法,但同时你必须考虑,这个选项是由Android本身。如果你在看了代码后给他一些关于如何应用良好实践的提示,这将非常有助于他解决这个问题。我的主要目标是解决这个问题,如果你去阅读它的链接,那么很明显,你必须减少内存的使用。
