|

|
|

|
|
* In the ClassHierarchy a MiniModel will be known as "AndroidModelClass.???Model" (where ??? is the

* AndroidComponent) and be called by "AndroidModelClass.startUnknown???" (which is generated by the
|
|
* UnknownTargetModel).
|
|
*
|
|
* A MiniModel is used when a startComponent-call (startActivity, bindService, ...) is encountered, but
|
|
* the Context at the call site is insufficient to determine the actual target. In this case an
|
|
* UnknownTargetModel which uses an MiniModel and an ExternalModel is placed there.
