Edit: This question was made when I assumed that apps put their web cache into the stock browser's own cache. This is not the case. Apps usually put this data into their own
app_webview folder. I'll keep this question up though since Izzy's answer is a good one.
I have a Sony Xperia E3 running Android 4.4.2, and after using AppInventor for some time the inbuilt browser (aka the stock Android browser) has taken up a large amount of storage space with the cache.
Since the stock browser technically isn't installed I can't access the menu to clear the cache.
Is there any way to clear the cache without factory resetting/rooting?
