原标题：Weird memory issue on Samsung Galaxy Note

My application crashes on the Samsung Galaxy Note, apparently due to memory issues. The weird part is that my app does not appear to be using a particularly large amount of memory at the time of the crash. However, according to the logs, the OS seems to think that memory is running low and starts killing all active processes (including my app). I don t see this behavior on any other device I ve tried (test devices include: Acer Iconiatab, Samsung Galaxy Tab, Droid3 phone, Nook color, LG Optimus V).

我怀疑,这与安装在装置上的roid子有关,在处理低记忆状态时可能有些虚弱和错误。 有什么想法可导致这种行为,或建议我如何加以纠正?

停车场收集记录在死亡前即刻,显示记忆使用量不大(我知道这些记录来自我根据个人资料数据库所做的评估):

Go into developer options under settings. You probably have something checked on like:
