start activity but in background

My application will launch a new activity (say calculator) using intents开发者_Python百科.

My requirement is: Is there any way to start the new activity in background (not in foreground)?

Can you suggest any solution?

thank you

Short version : Use threads.

Not-so-long version : read about threads.

What do you want to do exactly? Depending on that, you have several options:

• You can use an AsyncTask
• You can use a local Service
• You can use a remote Service
• You can use a Thread

Use BroadcastReceiver to receive the Intent and start Service or Thread do what you want to do.
