问题 There is a way to call javascript function from webview and then let it call a method in Java to return the result. Like described in How to get return value from javascript in webview of android? Now, the javascript function can fail (say due to a typo in javascript file). In that case, I would like to carry out some failover code in Java. What is a good way to do that? My current code looks like this: In Java: private boolean eventHandled = false; @Override public void onEvent() {

问题 Edit: I have looked at the error page for this; no answers work. It seems it is an Android system bug that has not yet been solved. First off I've referred to this similar question.

I'm looking for a way to see more debug messages from the WebView or a way to get the video playing. Using Android 4.4.4 by the way. View layout = LayoutInflater.from(mActivity)

问题 I have a WebView in my Android app, and I need to run a JavaScript function whenever the app/WebView is switched to (e.g. using the app switcher or tapping the icon from the home screen) the device wakes from sleep (with the app having still been on the screen when the device went to sleep). Using a visibilitychange event listener in my webpage javascript only works for case 1. Ideally I would like to trigger some kind of javascript event using the Android onResume() java function, but how?
