launch facebook app from other app

How can 开发者_运维百科I launch a facebook app from my app in android?

Looking at the latest Facebook apk (1.6), it looks like both "facebook://" and "fb://" are registered protocols.

facebook://

facebook:/chat
facebook:/events
facebook:/friends
facebook:/inbox
facebook:/info
facebook:/newsfeed
facebook:/places
facebook:/requests
facebook:/wall

fb://

fb://root
fb://feed
fb://feed/{userID}
fb://profile
fb://profile/{userID}
fb://page/{id}
fb://group/{id}
fb://place/fw?pid={id}
fb://profile/{#user_id}/wall
fb://profile/{#user_id}/info
fb://profile/{#user_id}/photos
fb://profile/{#user_id}/mutualfriends
fb://profile/{#user_id}/friends
fb://profile/{#user_id}/fans
fb://search
fb://friends
fb://pages
fb://messaging
fb://messaging/{#user_id}
fb://online
fb://requests
fb://events
fb://places
fb://birthdays
fb://notes
fb://places
fb://groups
fb://notifications
fb://albums
fb://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_10100412949637447

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/inbox
facebook://facebook.com/info?user=544410940     (id of the user. "patrick.boos" won't work)
facebook://facebook.com/wall
facebook://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/notifications
facebook://facebook.com/photos
facebook://facebook.com/album
facebook://facebook.com/photo
facebook://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.

If any one want to directly open a photo

public Intent getOpenFacebookIntent(String pId) {
    try {
        activity.getPackageManager().getPackageInfo("com.facebook.katana", 0);
        return new Intent(Intent.ACTION_VIEW, Uri.parse("facebook:/photos?album=0&photo=" + pId + "&user=" + ownerId));
    } catch (Exception e) {
        return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/"));
    }
}

startActivity(getOpenFacebookIntent(pid));

where ownerId is the Facebook id of the user who uploaded this picture and pid is PhotoId

Enjoy :))

Launching of another application from your application in android, can be done only if Intent action you fire matches with intent filter of other application you want to launch.

As @patrick demonstrated, download facebook.apk to emulator and try to run that through adb shell command. It works fine..

Pass Intent filter and data as an Uri

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/groups/14531755***6215/")));

This directly opens facebook group having the id: 14531755***6215 inside fb app
