In my Android application, if I download some JavaScript from a web URI, can that JavaScript read my native files like shared preferences or other files which I stored in my application’s location?
Any ideas?
Generally, no. If it is running in a WebView and you have hooks to native methods in that (via
addJavascriptInterface()), and the JS code you download knows (or guesses) what they are, it might be able to call them. Which could technically result in it reading files.
