Hi,
I am working on a fairly complex bit of code. I would like your input to
understand which (if any at all) of the above classes I should use.
The short description is that I have an Activity that displays local HTML5
within a WebView. The WebView utilises a WebViewClient which intercepts URL
requests from the HTML5 implementation (I realise that on Android the
HTML5/javascript implementation can directly call native code but
unfortunately the HTML5 needs to be x-platform (i.e. run on iOS) so I am
forced to communicate through intercepting URL's that are being loaded).
The application also has a separate Thread that I use to communicate with
an external server across the network.
1: When the native Android code wants to do a javascript call in the
WebView object, does this need to be done via the main application thread
or could for instance the external server Thread do a
WebView.loadURL("javascript:......") directly?
2: Is the HTML5/javascript implementation run by the main thread? In other
words, is the WebViewClient.shouldOverrideUrlLoading(....) called by the
main application thread?
3: I implemented PUSH notifications within the application and I am
currently using a BroadCastReceiver in my Activity to receive broadcast
messages from the cloud messaging IntentService I added. As the Activity
already contains a Broadcastreceiver - should the external server Thread
(in case the answer to 1 is yes) and the WebViewClient (in case the answer
to 2 is no) also send a broadcast message to report to the Activity or
should I implement an additional message Handler?
- on a sidenote .. I just read that I cannot perform timeconsuming actions
from the BroadcastReceiver.onReceive(....) method. (apparently not even
open pop-up dialogs although that is exactly what I do and works fine on
both the simulator and a range of real devices) ... what is the solution
here?
Hope I explained the situation clear enough :)
Cheers,
Lieuwe
