国内 Top500Android 应用分析报告

<h2>背景</h2> <p>笔者目前在开发的应用在线上有不少OOM的问题，经过一番优化后，OOM降了一个量级，但由于产品中Gif是一特色，内存占用优化空间比较有限，想要减少OOM最简单的办法可能就是开启largeHeap。Google官方是不推荐使用largeheap的，更大的内存意味着更长的垃圾回收时间，所以我就想看看国内的这些应用是否有打开largeheap。用AS的APK Analyzer看了下微信和QQ空间，发现大家都打开了，然后我就安心了。</p> <p>后来，我们打算把Jackson库换掉，太占用方法数了，可选择的有Gson和Fastjson。同样去看看国内的App都在用什么吧，本以为Fastjson号称速度最快，国内又是主场，应该用的人更多一些，但在手动分析了几个APP后，发现大家都在用Gson，Fastjson反而没见到几个。</p> <p>再后来，有一天晚上，好像看了篇TK教主的文章就来了灵感，觉得可以批量分析一下国内主流的APP，看看大家都在用什么库，教父整天说据我所知，国内用哪些团队在用rxjava，我可以来个更全面准确的分析，顺便可以看看我的Nuwa是否有人在用？</p> <h2>分析</h2> <p>豌豆荚正好那几天被收购了，那就拿他开刀吧，脚本下载了排行榜（周下载量）Top500的应用，使用Android SDK自带的appt和dexdump，分析Manifest文件和dex文件，拿到一些APK基本信息和dex中的Class Descriptor。</p> <p>有些有插件化能力的或者没有用MultiDex的应用，可能dex不在常规位置，比如淘宝把dex伪装成.so文件，所以需要查看文件的magic number来找到dex文件。</p> <p>涉及到数据的排序和整理，所以使用了mysql数据库，Class Descriptor通过package分段聚合，package最多保留四段，比如Lcom/jiajixin/nuwa/utils/dex/,会有 com/* 、 com/jiajixin/ 、 com/jiajixin/nuwa/ 、 com/jiajixin/nuwa/utils/ 入库,然后group by后根据count倒序输出，人工匹配对应库名。</p> <h2>数据</h2> <p>废话不多说，直接展示数据。</p> <h3>APK基本信息</h3> <p><img src="https://simg.open-open.com/show/d8068adaa25388f445d1fa9e5eee32c3.jpg"></p> <p><img
