public void start(final BundleContext bundleContext) throws Exception

Implements org.osgi.framework.BundleActivator.start.

Doc from org.osgi.framework.BundleActivator.start.

Called when this bundle is started so the Framework can perform the bundle-specific activities necessary to start this bundle. This method can be used to register services or to allocate any resources that this bundle needs.

This method must complete and return to its caller in a timely manner.

Parameters
bundleContext:BundleContext

The execution context of the bundle being started.

Annotations
@Override
Exceptions
Exception:
If this method throws an exception, this bundle is marked as stopped and the Framework will remove this bundle's listeners, unregister all services registered by this bundle, and release all services used by this bundle.
stopback to summary
public void stop(final BundleContext bundleContext) throws Exception

Implements org.osgi.framework.BundleActivator.stop.

Doc from org.osgi.framework.BundleActivator.stop.

Called when this bundle is stopped so the Framework can perform the bundle-specific activities necessary to stop the bundle. In general, this method should undo the work that the BundleActivator.start method started. There should be no active threads that were started by this bundle when this bundle returns. A stopped bundle must not call any Framework objects.

This method must complete and return to its caller in a timely manner.

Parameters
bundleContext:BundleContext

The execution context of the bundle being stopped.

Annotations
@Override
Exceptions
Exception:
If this method throws an exception, the bundle is still marked as stopped, and the Framework will remove the bundle's listeners, unregister all services registered by the bundle, and release all services used by the bundle.
