android - 三星 Galaxy Note 上奇怪的内存问题

标签 android

我的应用程序在 Samsung Galaxy Note 上崩溃，显然是由于内存问题。奇怪的是，我的应用程序在崩溃时似乎没有使用特别多的内存。但是，根据日志，操作系统似乎认为内存不足并开始终止所有 Activity 进程(包括我的应用程序)。我在我尝试过的任何其他设备上都没有看到这种行为(测试设备包括:Acer Iconiatab、Samsung Galaxy Tab、Droid3 手机、Nook color、LG Optimus V)。

我怀疑这与设备上包含的 android 构建有关，也许它在处理低内存情况时做了一些时髦和错误的事情。关于什么可能导致这种行为的任何想法，或关于我如何纠正它的建议？

死前的垃圾收集日志显示适度的内存使用(我知道这些来 self 的基于 PID 的应用程序):
