definition IOC & DI
source: http://wikipedia.com
In software engineering, Inversion of Control (IoC) is an object-oriented
programming practice whereby the object coupling is bound at run time by
an "assembler" object and is typically not knowable at compile time using
static analysis.

Dependency injection is a software design pattern that allows a choice of
component to be made at run-time rather than compile time. This can be
used, for example, as a simple way to load plugins dynamically or to choose
mock objects in test environments vs. real objects in production
environments.

annotation types part 1

! @Inject
! standard Guice annotation
! @InjectView(resId)
! inject views after „setContentView()“ in „onCreate()“
! @InjectResource(resId)
! inject resource in „onCreate()“
! @InjectExtra(extraName)
! inject extra only in „onCreate()“ NOT „onNewIntent()“
! @InjectPreference(keyName)
! reads preference by keyName
! @InjectFragment(resId, tagName)
! inject the fragment to the resId with the tagName


annotation types part 2

! @ContentView(resId)
! set layout for activity/ fragment
! @Named(valueName)
! with the valueName a specific configuration can be
done
! no annotation but related Provider<T>
! asynchronous injection, if the creation is expensive and
not always used. The method #get() can be used
