How to limit DEX memory usage

阅读更多关于 How to limit DEX memory usage

问题 I am trying to set the maximum memory that DEX task can use in a gradle-based Android project, but can't find any option to do that. My motivation to do this is because as dex sometimes takes so much memory that my computer starts swapping and becomes completely unresponsive for some minutes (so I would rather see the task fail and then free some more resources and retry) In my gradle.properties I have org.gradle.jvmargs="-Xmx300m" which limits the memory used by Gradle itself, but when

APP可视化埋点原理大揭秘

【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 一、背景运营者能够对用户行为进行分析的前提，是对大量数据的掌握。在以往，这个数据通常是由开发者在控件点击、页面等事件中，一行行地编写埋点代码来完成数据收集的。然而传统的操作模式每当升级改版时，开发和测试人员就需要重复不断对代码进行更新，整个流程耗时长，无法满足业务的需求。为帮助开发者解决这一痛点，个推应用统计“个数”推出“可视化埋点”这一技术来更高效地实现这个这一过程。“个数”的可视化埋点灵活、方便，开发者不需对数据追踪点添加任何代码，只需要连接管理台并圈选页面中需要埋点的元素，即可添加随时生效的界面追踪点。本文将结合个数实践经验，对可视化埋点中的两大关键技术点即控件唯一标识和事件采集进行分析并提供解决方案。二、可视化埋点关键技术点可视化埋点的难点，或者说核心就是如何在开发者不编写任何代码的情况下，SDK 如何确定任意一个控件在该应用内的唯一性，以及如何监听控件的点击和页面的切换。标识为了防止不同页面中的控件标识重复出现，控件的唯一标识一般由页面标识加上控件标识生成。页面标识生成页面标识可以直接使用页面的名称，即 Activity name。其获取方式比较多，这里介绍一种比较通用的方法，即通过注册 Application.ActivityLifecycleCallbacks
