The reference is removed when the WebView on top is destroyed (user exits the WebView with back button etc.).
Sorry, that reference is not problematic since that is just the reference of the LeadboltAppWallActivity which is used for the progress dialog (when user clicks on an ad which takes to Google Play - until the urls don’t resolve finally to market:// link the progress dialog remains on). The whole of the progress dialog part could probably be replaced by some Toast.makeText() so user doesn’t get impatient (if they are on a slow GPRS connection for instance).
The reference to activity which COULD be problematic is the one passed into the static method for prefetch:
tryToPreLoadUrl()
which creates a WebView - the handler for which responds to click on ad by launching intent to goto Google Play.
And it COULD happen that you pass in the reference to activity which was in foreground at that time - but later you switch activities and the original activity could be killed off or something - I don’t know if that could cause a problem.
But regarding not wanting to use reference to activity (so it not hinder garbage collection) - one COULD perhaps instead of using “final Activity activity” use a static variable that holds the reference - and when the WebView has on onPause() or something we set that reference to null.
And then to be sure, in the LeadboltAppWallActivity onPause() also set that variable to null.
Maybe missing some checks for null references - in my own use of the above code, saw one type of very rare error only in Google Developer Console and that should be fixed by this:
if (progress == null) {
progress = new ProgressDialog(adActivityForUseByProgressDialog);
// ISSUE_WERE_GETTING_ERROR_ON_PROGRESS_SHOW_SO_PUT_IN_CHECK_FOR_NULL
if (progress != null) {
progress.setMessage("Loading...");
}
}
// ISSUE_WERE_GETTING_ERROR_ON_PROGRESS_SHOW_SO_PUT_IN_CHECK_FOR_NULL
if (progress != null) {
progress.show();
}
May also want to return if these variables are null:
When I used that code in my app, it shows the progress dialog for some time and then a system alert comes that the app is not responding, you want to close it?
@javaexp were you ever able to figure out why it says “This content is not available for viewing at this time.”? I’m getting the same thing. I’d much rather show the app wall via the web view this way instead of adding all of the SDK components. Do you think emailing my account manager about question would do any good?
For my new game i added a More Apps button ( it looks like a Shopping Bag full of apps) that triggers the Html appwall when clicked. Is this Google compliance? Thank you!
