Method Detail

inject

public static void inject(Activity activity)

Injects activity if an associated AndroidInjector.Factory implementation can be found, otherwise throws an IllegalArgumentException.

Throws:

RuntimeException - if the Application doesn't implement HasDispatchingActivityInjector, or if no AndroidInjector.Factory<Activity, ?> is bound for activity.

inject

public static void inject(Fragment fragment)

Injects fragment if an associated AndroidInjector.Factory implementation can be found, otherwise throws an IllegalArgumentException.

Uses the following algorithm to find the appropriate DispatchingAndroidInjector<Fragment> to inject fragment:

1. Walks the parent-fragment hierarchy to find the a fragment that implements HasDispatchingFragmentInjector, and if none do
2. Uses the fragment's activity if it implements HasDispatchingFragmentInjector, and if not
3. Uses the Application if it implements HasDispatchingFragmentInjector.

If none of them implement HasDispatchingFragmentInjector, a IllegalArgumentException is thrown.

Throws:

IllegalArgumentException - if no AndroidInjector.Factory<Fragment, ?> is bound for fragment.
