| 31 | * An extension of {@link android.content.ContentResolver} that is designed for |
| 32 | * testing. |
| 33 | * </p> |
| 34 | * <p> |
| 35 | * MockContentResolver overrides Android's normal way of resolving providers by |
| 36 | * authority. To have access to a provider based on its authority, users of |
| 37 | * MockContentResolver first instantiate the provider and |
| 38 | * use {@link MockContentResolver#addProvider(String, ContentProvider)}. Resolution of an |
| 39 | * authority occurs entirely within MockContentResolver. |
| 40 | * </p> |
| 41 | * <p> |
| 42 | * Users can also set an authority's entry in the map to null, so that a provider is completely |
| 43 | * mocked out. |
| 44 | * </p> |
