How can I run a sequence of applications or actions on certain triggers on Android?

Question

Is there is free application or some trick to run sequence of applications on android? For example I want to start the following sequence: Wi-Fi --> Tor --> Browser

Answer 1

You should try Tasker for simple interface and quick setup.

If you are willing to do something by code and very specific, a good alternative is onX by Microsoft, you can write your code to do exactly the things you wanna do. Also there are some ready recipes that you can quickly setup.

Answer 2

For newer phones, you can use Automagic, which has almost all of the functionality of Tasker (at the time of this writing, and expanding) and has a much better interface for editing your sequences. It also makes use of the newer Holo themes on Android 4.0 (Ice Cream Sandwich) and later.

Answer 3

The simpler automation apps can probably only start a single app, or maybe more, but not in sequence. The more advanced apps that can perform this is either the trusted old Tasker (paid), or the newer Automate (free).
