시스템 서비스에 접근하기

사용가능한 서비스 리스트 출력 예

android.os.IServiceManager sm = android.os.ServiceManagerNative.getDefault();
try {
	String[] services = sm.listServices();	
	for (int i = 0; i < services.length; i++) {
		Log.i("Services", i + " : " + services[i]);
	}
} catch (DeadObjectException e) {
	Log.i("Services", e.getMessage(), e);
}

아래는 애플리케이션에서 이용가능한 API 목록입니다. 단, 인터페이스에 접근할 수 있다고 해서 사용가능한 거랑은 다릅니다. 왜냐면 적절한 권한이 요구될 수 있기 때문입니다.

또한 출처 워낙 글이 옛날(2007. 12. 14)꺼라 인터페이스 이름이 변경된 서비스들이 있을 수 있습니다.
