Question

I currently have 2 apps in the market, let’s call them app A and app B.

When a certain function is executed in app, I need something to trigger an event in app a, even if app a isn’t currently running. I assume app B would send a broadcast message to app a and app a would need a broadcast receiver but I am not sure how this can be done, if it can be done.

Answer 1

There are basically two ways afaik:

• Broadcast Receiver and using the sendBroadcast method on the sender side

or by using Intents:

• you can use startActivity(Intent) even with another app, but this will bring the app to foreground rather than doing a job in background.

Use intents if the calling app should dissappear and the called app should be in foreground and use broadcasts if you just want a background task performed by another app
