Hi,
I've been working on this today and haven't managed to make it happen
yet.
I registered an intent-filter for an activity in my
AndroidManifest.xml like this:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category
android:name="android.intent.category.DEFAULT" />
<category
android:name="android.intent.category.BROWSABLE" />
<data android:mimeType="myapp/zzz" />
</intent-filter>
When I click a link from the browser to a ".zzz" file with a content-
type value "myapp/zzz" (I verified this by looking at the headers of
the server response) I get 2 kinds of errors:
1. A dialog box saying: "Error. Unable to download file as content
type is not supported"
the logcat trace for this is:
INFO/ActivityManager(518): Starting activity: Intent
{ action=android.intent.action.VIEW data=http://www.mysite.com/
myfile.zzz comp={com.google.android.browser/
com.google.android.browser.BrowserActivity} }
DEBUG/browser(3255): *-* Start browser instrument
VERBOSE/favicons(3255): Starting load with icon 0x0 for
http://www.mysite.com/myfile.zzz
DEBUG/(3255): removing file '/sdcard/download/myfile.zzz-part'
2. An uncaught exception displayed as a dialog box giving the "Unable
to add window" error. logcat trace is:
WARN/WindowManager(518): Attempted to add application window with
unknown token HistoryRecord{402d80b0 {com.google.android.browser/
com.google.android.browser.BrowserActivity}}. Aborting.
DEBUG/dalvikvm(3572): Exception Landroid/view/WindowManager
$BadTokenException; from ViewRoot.java:186 not caught locally
DEBUG/dalvikvm(3572): Exception Landroid/view/WindowManager

WARN/dalvikvm(3572): threadid=3: thread exiting with uncaught
exception (group=0x4000fdf8)
ERROR/AndroidRuntime(3572): Uncaught handler: thread Main exiting due
to uncaught exception
...
Apparently, the second error happens after I clear the browser cache,
and from that point I get the first error.
Seems like the intent for the mime type I specified is not found -
although I'm not sure.
Perhaps I should mention that I managed to get my activity fired by
registering a scheme in an intent filter using:
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category
android:name="android.intent.category.DEFAULT" />
<category
android:name="android.intent.category.BROWSABLE" />
<data android:scheme="zzz" />
</intent-filter>
but this means I need to handle the file download myself (not much of
a problem), but worse, that this is a very proprietary kind of URI
scheme that I think is good to avoid.
Any ideas?
Anyone managed to get their activities launched by the browser after
downloading a file using a mimeType intent-filter?
Thanks!
Amos.
P.S.
I'm using m5-rc15.
