I want to test a Service with my Application class pre-instantiated, a bit like what happens on a real device.
My problem is I can't figure out a way to do this with the correct Application context AND having the Application being instantiated EXACTLY once. Being instantiated multiple times causes issues if there is code which uses singletons, and/or performs registrations tasks that should only be performed once. Full code for this snippet can be downloaded here: http://www.zedray.co.uk/temp/ServiceSnippet.zip My test code: ============================= public class ServiceDemoTest extends ServiceTestCase<ServiceDemo> { protected final void setUp() throws Exception { /** Setup the MainApplication. **/ mApplication = (ApplicationDemo) Instrumentation.newApplication(ApplicationDemo.class, getContext()); mApplication.onCreate(); setApplication(mApplication); super.setUp(); } @Override protected final void tearDown() throws Exception { if (mApplication != null) { mApplication.onTerminate(); mApplication = null; } setApplication(null); super.tearDown(); } @MediumTest public final void testStartable() { startService(new Intent(getContext(), ServiceDemo.class)); } ============================= This produces the following trace, which suggests that several instances of my Application are being created, or just that onCreate() is being called several times: ============================= 05-21 16:20:43.667: INFO/ServiceSnippet(4126): ApplicationDemo.onCreate() mInstanceId[0] 05-21 16:20:46.398: INFO/ServiceSnippet(4143): ApplicationDemo.onCreate() mInstanceId[0] 05-21 16:20:46.437: INFO/ServiceSnippet(4143): ApplicationDemo.onCreate() mInstanceId[1] 05-21 16:20:46.447: INFO/ServiceSnippet(4143): ServiceDemo.onCreate() 05-21 16:20:46.447: INFO/ServiceSnippet(4143): ServiceDemo.onStart() 05-21 16:20:46.466: INFO/ServiceSnippet(4143): ApplicationDemo.onCreate() mInstanceId[2] 05-21 16:20:46.488: INFO/ServiceSnippet(4143): ApplicationDemo.onCreate() mInstanceId[3] ============================= I have no idea why the onCreate() keeps getting called, and how to ensure it only happens once. Is this possible? Any ideas? Regards Mark -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
