creating a pending intent to start a non system app

Question

I've read plenty of doc, but I still can't figure it out.

Are we allowed to start a 3rd party app(NON SYSTEM APP like as alarm, notification. etc) with a pending intent?

i.e.:

App1

• create pending intent
• start a non system app and send pending intent

App2

• execute its own code
• call pending intent to start App1

I haven't found 1 single example doing this. And according to the doc. you can pass a pending intent to a 3rd party app. It does not specify a system app

does it make sense?

Answer 1

Yes, you may launch anything you want with a PendingIntent. As long as the component you want to start is exported (publicly available).
