How can I know the intents needed to open system activities

Question

I have the need to open android's default screen settings, and previously I wanted to open android's default alarm configuration activity, in the future I'm thinking I would want to open GPS settings.

How can I get the information needed to start this activities? Where can I found the documentation about this? What's the process for getting this information without googling for the specific activity?

Answer 1

Check the Common Intents listing in the documentation.

It's a pretty comprehensive listing of the actions, URI formats and MIME types for building Intents for the standard Android applications.

Answer 2

There is a list of Actions in the documentation listed here .

You can launch any of the sub activities in the settings app using something like:

startActivity(new Intent(Settings.ACTION_WIFI_SETTINGS));
