How can I fix a SecurityException error when an app activity isn't exported?

[mattga...@gmail.com]

I have a block that intends to start the Facebook and Messenger apps. When I test my flow, I get the following error:

java.lang.SecurityException: Permission Denial: starting Intent { flg=0x10040000 cmp=com.facebook.katana/.dbl.activity.FacebookLoginActivity } from ProcessRecord{f50015b 10996:com.llamalab.automate:background/u0a265} (pid=10996, uid=10265) not exported from uid 10122

Is there a solution?

The activity you're trying to start is private (not exported) so other apps can't start it.

On a rooted device, it may be possible to start it using the Shell command superuser block to execute:

am start -n com.facebook.katana/.dbl.activity.FacebookLoginActivity

Any solutions for an unrooted phone, or am I simply unable to start the Facebook apps at all?

[Henrik "The Developer" Lindqvist]

Not for the specific activity. To start the Facebook app, just set the package and leave the other fields empty.

Wow, total noob right here - I thought that in order to start an app, I had to choose both the package and activity.

Anyway, that worked! Thanks for the help :)

To implicitly start the “main” activity, like the launcher does, specify only the package.
