cmd scheme 啟動application

To just start the default Launcher Activity: Intent intent = new Intent("android.intent.category.LAUNCHER");intent.setClassName("com.facebook.katana", "com.facebook.katana.LoginActivity");startActivity(intent); I did some research, because I wanted to find this out :). I found some ways how to start different activities easily. But I can not guarantee that this will work after upgrades of facebook. I tested it with my current facebook app and it works. At least I tested it with "adb shell" using "am start .....". Basic is: String uri = "facebook://facebook.com/inbox";Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(uri));startActivity(intent); the facebook.com part is not checked. you can even type: "facebook://gugus.com/inbox" having the same effect. How to do this in adb. 1. Start adb shell through console: "adb shell"2. run: "am start -a android.intent.action.VIEW -d facebook://facebook.com/inbox" this will start the inbox activity.Here some Uris with examples. I think they speak for themselves what they do. facebook://facebook.com/inboxfacebook://facebook.com/info?user=544410940     (id of the user. "patrick.boos" won't work)facebook://facebook.com/wallfacebook://facebook.com/wall?user=544410940   (will only show the info if you have added it as friend. otherwise redirects to another activity)facebook://facebook.com/notificationsfacebook://facebook.com/photosfacebook://facebook.com/albumfacebook://facebook.com/photofacebook://facebook.com/newsfeed there might be additianl parameters you can give to certain of those uris, but I have no time to go through all the code of those activities. How did I do this? check out apktool. link|improve this answer edited Nov 16 '10 at 7:01 answered Nov 16 '10 at 6:55 Patrick Boos 1,319513

It seems like this doesnt work anymore ( and it definitely used to!). facebook://facebook.com/wall?user=1230123 just opens Facebook to the Stream activity, and not the wall of the specified user. – NPike Jul 9 '11 at 23:33   Figured it out, see my post below about the new protocols. – NPike Jul 10 '11 at 0:17   Hello Patrick: Here it opens up the installed facebook app,But i need to open the facebook app with the update status opened along with the image attached to the status , how to achieve this ...?any help is greatly appreciated ... – Rajesh Rs Jan 19 at 12:20   sorry.. i guess those were from a older version. check out @NPike's post. Those might be the ones you need – Patrick Boos Jan 20 at 1:19 1   What happens if the application isn't installed ? – Gp2mv3 Jan 26 at 19:43 show 3 more comments feedback

Looking at the latest Facebook apk (1.6), it looks like both "facebook://" and "fb://" are registered protocols. facebook:// facebook:/chatfacebook:/eventsfacebook:/friendsfacebook:/inboxfacebook:/infofacebook:/newsfeedfacebook:/placesfacebook:/requestsfacebook:/wall fb:// fb://rootfb://feedfb://feed/{userID}fb://profilefb://profile/{userID}fb://page/{id}fb://group/{id}fb://place/fw?pid={id}fb://profile/{#user_id}/wallfb://profile/{#user_id}/infofb://profile/{#user_id}/photosfb://profile/{#user_id}/mutualfriendsfb://profile/{#user_id}/friendsfb://profile/{#user_id}/fansfb://searchfb://friendsfb://pagesfb://messagingfb://messaging/{#user_id}fb://onlinefb://requestsfb://eventsfb://placesfb://birthdaysfb://notesfb://placesfb://groupsfb://notificationsfb://albumsfb://album/{%s}?owner={#%s}fb://video/?href={href}fb://post/{postid}?owner={uid}¹ Sorry if I missed some... only played with a handful of them in the emulator to see if they actually work - a bunch of them will cause the Facebook application to crash. ¹ where postid is in the uid_postid format, e.g 11204705797_10100412949637
