我们都知道,Java的字节码(Bytecode)本质上就是一个字节数组,或者字节流。类似的,Bitcode本质上就是一个比特序列,或者叫做比特流。从字面上看就知道,bitcode信息密度要比bytecode大一些,也就是说更紧凑一些。例如说要表示布尔值,在字节码里就需要一个字节,有7个比特是浪费的;但是在bitcode里,只要一个比特即可。读完本文后,

在Android开发过程中,Bitmap往往会给开发者带来一些困扰,因为对Bitmap操作不慎,就容易造成OOM(Java.lang.OutofMemoryError - 内存溢出),本篇博客,我们将一起探讨Bitmap的性能优化。 为什么Bitmap会导致OOM? 1.每个机型在编译ROM时都设置了一个应用堆内存VM值上限dalvik.vm.heapgrowthlimit,用来限定每个应用可用的最...
