Answer 1

这个问题的答案取决于你如何在应用程序中使用 byte[] 的代码。

如何解决？

• 检查您正在初始化 byte 数组的应用程序
• 在循环迭代中重复使用数组元素
• 在不使用时使数组引用无效

检查带有标签的 logcat 消息:dalvikvm 并运行您的应用程序。检查哪里

D/dalvikvm(28039): GC_CONCURRENT freed 473K, 7% free 9503K/10180K, paused 2ms+3ms, total 22ms

1. 7% 免费 9503K/10180K -

9503K is amount which is holding live object references in our application. As you traverse inside your application, this value will grow up. This is normal. BUT parallely GC is also running and trying to free resources/object references which are not strongly connected. If you do not find value 9503K go down then this is warning to us. This is signal that our application is certainly leaking memory.
