Traditional Web browsing involves typing a URL on a browser and loading a Web page. In contrast, there is another form of Web browsing on mobile devices, i.e., embedded Web browsing, which occurs when mobile apps embed a Web page within the app. When the user navigates to the specific page in the app, the Web page is loaded from within the app. However, little is known about the prevalence or performance of these embedded Web pages. To analyze the embedded Web browsing performance at scale, we design and implement DroidMeter, a tool that can automatically search for embedded Web pages inside apps, trigger page loads, and retrieve performance metrics.
