Dynamic Registration vs Static Registration of BroadcastReceiver

Question

All of us known we register BroadcastReceiver in two types

1)Static Registration

2)Dynamic Registration

But my doubt is when we need to use Static and when we need to use Dynamic?

Answer 1

As we know there are two ways to register a BroadcastReceiver; one is static and the other dynamic.

Static:

1. Use tag in your Manifest file. (AndroidManifest.xml)
2. Not all events can be registered statically.
3. Some events require permissions.

Dynamic:

1. Use Context.registerReceiver() to dynamically register an instance.
2. Note: Unregister when pausing.

When we are doing dynamic registration (i.e. at run time) it will be associated with lifecycle of the app. If we do it static registration (i.e. on compile time) and our app is not running, a new process will be created to handle the broadcast.

Answer 2

1) Static Registration

Implementation are in manifest, android system can initiate processes and run your boardcast receiver. One example like you want to update your data when a new intent coming in from system or etc.. You need to take care Security issue as well.

2) Dynamic Registration

Implementation are in java code, boardcast receiver runs only when your app is running up to that registration line. Thus, you mostly want to use this if you only want to bring up the boardcast receiver with certain conditions.
