活动需要140mb内存
Kim*_*Kim 2 java android memory-leaks memory-management
我正在尝试创建一个社交媒体应用程序.但它占用了大约300mb的内存.所以我的主页上有5个包含帖子的片段.总体而言,内存使用量为250-300mb
然后进行测试,我禁用了这些碎片,但仍然主动活动消耗140mb没有任何大的操作.
所以,
这是我的课
public class HomePage extends AppCompatActivity {

Full Class:here 在该类中没有添加任何片段,但内存使用量为120-140
我敢肯定,我在所有其他活动或片段中重复同样的错误.一旦我知道了问题,我可以将其修复为其他部分.
需要帮忙 :(
我认为这是正常的.它实际上并没有吃掉140MB的RAM.在AS3的新Android监视器上,数字与之前的AS2略有不同.在这里的用户指南中,它写道:
与以前的Android Monitor工具的内存计数相比,新的Memory Profiler 会以不同的方式记录您的内存,因此您的内存使用现在看起来更高.Memory Profiler监视一些增加总数的额外类别,但是如果您只关心Java堆内存,那么"Java"编号应该类似于上一个工具的值.
尽管Java编号可能与您在Android Monitor中看到的完全匹配,但新编号会占用已分配给应用程序Java堆的所有物理内存页,因为它是从Zygote分叉的.因此,这可以准确表示您的应用实际使用的物理内存量.
目前,Memory Profiler还会在您的应用中显示一些实际属于性能分析工具的误报本机内存使用情况. 为~100k对象添加了高达10MB的内存.在未来版本的工具中,这些数字将从您的数据中过滤掉.
我曾经在我以前的应用程序上看到200MB +,它有4个底部导航片段(在Leakcanary上没有找到任何内容).
