- I have Activity with some data displayed in WebView that I load with
WebView#loadDataWithBaseURL - Then I have/click menu option that fires
android.content.Intent.ACTION_SEND - Choose email from the chooser
- Google email comes up (as expected)
- Discard email and hit back button
- Action with WebView tries to
resume - Bang - I get NullPonterException at line 4380 in WebView.java
if (mWebViewCore.getSettings().getNeedInitialFocus())since mWebViewCore is now null
The only place in code where mWebViewCore is nullified is at WebView#destroy - how do I recover from this? Do I need to r开发者_StackOverflow社区ecreate the browser and load my data all over again, that seems pretty wasteful? I really appreciate good suggestion at this point
Well, I can tell you that I just tested using a WebView with loadDataWithBaseURL(), where the page I loaded had a link. Clicking on the link brings up the Browser application, as expected. BACK button-ing out of the Browser brings back my app with the WebView just fine, no exceptions.
So, either ACTION_SEND/Gmail are somehow special, or there is something more going on with your app.
Can you replicate the problem in a small project that you can post somewhere?
