Permission Denial for intent to external activity

问题

My whole idea is a little more complex, but just to break things down so they're simple and to the point here...I have a button on a widget that i need to open the "places" activity in the official facebook app.

Here's the code i'm using:

 Intent PlacesIntent = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.facebook.katana", "com.facebook.katana.activity.places.PlacesNearbyActivity"));
            PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, PlacesIntent, 0);
            views.setOnClickPendingIntent(R.id.places, pendingIntent);

I get this error in the logcat:

 11-06 22:26:48.117: WARN/ActivityManager(85): Permission denied: checkComponentPermission() reqUid=10055
    11-06 22:26:48.117: WARN/ActivityManager(85): Permission Denial: starting Intent { act=android.intent.action.MAIN cat=[android.intent.category.LAUNCHER] flg=0x10000000 cmp=com.facebook.katana/.activity.places.PlacesNearbyActivity bnds=[371,129][428,203] } from null (pid=-1, uid=10157) requires null

If i use,

Intent PlacesIntent1 = new Intent(Intent.ACTION_MAIN).addCategory(Intent.CATEGORY_LAUNCHER).setComponent(new ComponentName("com.facebook.katana", "com.facebook.katana.HomeActivity"));
            PendingIntent pendingIntent1 = PendingIntent.getActivity(context, 0, PlacesIntent1, 0);
            views.setOnClickPendingIntent(R.id.facebook, pendingIntent1);

Everything works great and it opens the home activity, but that's not really what i'm trying to do.

I've tried

com.facebook.katana.activity.places.PlacesNearbyActivity - I actually see a respons in the logcat about the denail with this one
com.facebook.katana.activity.PlacesNearbyActivity
com.facebook.katana.places.PlacesNearbyActivity
com.facebook.katana.PlacesNearbyActivity

and nothing happens with the others

Here's what i see in the logcat when manually opening the activities on my phone:

11-06 20:20:38.295: INFO/ActivityManager(85): Starting activity: Intent { cmp=com.facebook.katana/.activity.places.PlacesNearbyActivity }

11-06 22:03:28.027: INFO/ActivityManager(85): Starting activity: Intent { flg=0x4000000 cmp=com.facebook.katana/.HomeActivity }

So, that gives you sort of an idea how i got my information.

Since it appears that Facebook does not endorse integration with their Android application this way, please do not do this.

Permission denied: checkComponentPermission() reqUid=10055

That activity can only be started by Facebook.

I disagree with Answer by CommonsWare. The answer is also not at all accepted, though I thought the answer is correct once, then I tried following code and found out that you can open place Activity from another app using following code...

appAction = Intent.ACTION_VIEW;
appPackage = "com.facebook.katana";
appActivity = "com.facebook.katana.IntentUriHandler";

data = Uri.parse("facebook:/places").buildUpon().appendQueryParameter("user", Long.toString(post.getSourceId())).appendQueryParameter("post", post.getPostId()).build();

Intent intent = new Intent(appAction);
intent.setClassName(appPackage, appActivity);

intent.setData(data);
ctx.startActivity(intent);
