> When you are talking about "reload the webview sometimes ...", I mean clicking the refresh button, or using the ctrl + r keyboard shortcut. I like never use window.reload. I don't really think Cordova caches anything. Cordova doesn't implement the webview and control over the webview is fairly limited. And everything inside the JS VM would be pretty much exclusive to the webview resources, things that Cordova cannot directly manipulate. As far as I know, resources related to a particular page is freed once the document is unloaded. What Cordova does do however, is allow plugins to be loaded up, which can hold some state/memory/whatever, and this state can persist through webview unloads/reloads, or even a complete destruction of the underlying native webview object, for as long as the application itself isn't killed. This wouldn't be included in the JS VM memory though as seen in the chrome web inspector (unless plugins are sending stuff to the webview and creating lots of JS objects). I don't have time to look at the application right now, but if I remember I'll try to look at it tomorrow (assuming I have power... hurricane season :D). In the meantime though, you might get better insights if you use the memory heap tools for collecting snapshots/allocations over time, which can also record stacktraces. After running through the reproduction a few times, you might be able to see a pattern. How large does the VM size grow anyway according to the dev tools? They can grow quite large, assuming device memory permits, up to ~1gb of RAM (regardless if device has plenty of RAM or not). You can also load up the project in Android Studio (the android studio project will be located at `<cordova-project-root>/platforms/android`, and utilise the performance audit tools to keep track of memory consumption, which will give you insights on what is happening on the native side (which would include webview memory usage, but you wouldn't be able to inspect the webview memory in detail like web inspector) -- This is an automated message from the Apache Git Service.
