Android Service do not working -

my app follow next scenarios...

1.[main activity]

• thread repeat sleep(5000)
• if thread sleep(), startservice()

2.[service.class] sendbroadcast()

3.[main activity - broadcastreceiver] toast()

---

thread working clean, service don't called.

i register in manifest.xml

and create broadcastreceiver dynamic.

check package imported, service here not android.app.service

context.startservice(new intent(mainactivity.this, service.class));
