  1. 我用过，adb shell dumpsys gfxinfo

为什么我的应用程序信息关于 Draw、Process、Execute adb shell dumpsys gfxinfo 为空？我不明白为什么要清空该统计信息。请帮帮我。

** Graphics info for pid 3213 [com.kabam.marvelbattle] **

在 AOSP 中存在几种渲染 UI 的方法：

  • 基于 SKIA 等 CPU 库
  • 基于硬件加速库——比如HWUI

对于上述日志，输出意味着 - 您的 Activity 不使用加速的 HWUI - 没有为您的 Activity 视图分配HardwareRenderer实现。dumpGfxInfo () API实现在这里没有输出 - 查看源

这是相关问题如何在 JB 上启用带有 GPU 后端的skia - 以启用 HWUI 利用率
