ComponentCallbackspublic interface ComponentCallbacks | The set of callback APIs that are common to all application components
({@link android.app.Activity}, {@link android.app.Service},
{@link ContentProvider}, and {@link android.app.Application}). |
| Methods Summary |
|---|
| public void | onConfigurationChanged(android.content.res.Configuration newConfig)Called by the system when the device configuration changes while your
component is running. Note that, unlike activities, other components
are never restarted when a configuration changes: they must always deal
with the results of the change, such as by re-retrieving resources.
At the time that this function has been called, your Resources
object will have been updated to return resource values matching the
new configuration.
| | public void | onLowMemory()This is called when the overall system is running low on memory, and
would like actively running process to try to tighten their belt. While
the exact point at which this will be called is not defined, generally
it will happen around the time all background process have been killed,
that is before reaching the point of killing processes hosting
service and foreground UI that we would like to avoid killing.
Applications that want to be nice can implement this method to release
any caches or other unnecessary resources they may be holding on to.
The system will perform a gc for you after returning from this method.
