Thanks for the pointer Jean-Baptiste.
I'll outline the problem I have at the moment to see if it is a
framework issue or one that's just down to my lack of knowledge.
The AndAppStore client uses a activity which contains a WebView to
display information about a specific application. When the user taps the
download link the activity detects it's a download and runs the
following code;
Intent loadIntent = new Intent
("android.intent.action.VIEW",Uri.parse(url));
loadIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
context.startActivity(loadIntent);
This ensures that the .apk is handled by the system apk installer.
Now the issue is that each time a user taps a download link the
startActivity call causes a new browser window to be created, and so if
they download a number of apps the browser eventually reports that too
many windows are open.
Now what I'd suggest is that some mechanism is introduced to allow
activities to re-use a browser window. From a developers point of view I
would suggest that setting the flag ACTIVITY_CLEAR_TOP should re-use the
last browser window created for the calling activity or create a new one
if a windows has not yet been created for that activity.
But I'm guessing this may not be the best approach from a framework
point of view....
