Ordered BroadCast in Android

Here is source code of the Program demonstrate an Ordered Intent in Android using Java. The program is successfully compiled and run on a Windows system using Eclipse Ide. The program output is also shown below.

When the order in which the Broadcast Receivers receive the Intent is important — particularly where you want to allow Receivers to affect the Broadcast Intent received by future Receivers — you can use sendOrderedBroadcast, as follows:

String requiredPermission = 
              “com.example.package_name.MY_BROADCAST_PERMISSION”;
sendOrderedBroadcast(intent, requiredPermission);

Using this method, your Intent will be delivered to all registered Receivers that hold the required permission (if one is specified) in the order of their specified priority. You can specify the priority of a Broadcast Receiver using the android:priority attribute within its Intent Filter manifest node, where higher values are considered higher priority.
