* <p>The following types of schema changes are not backwards-compatible. Supplying a schema
* with such changes will result in the provided callback being called with a {@link Throwable}
* describing the incompatibility, and the previously set schema will remain active:
* <ul>
* <li>Removal of an existing type
* <li>Removal of a property from a type
* <li>Changing the data type ({@code boolean}, {@code long}, etc.) of an existing property
* <li>For properties of {@code Document} type, changing the schema type of
* {@code Document Documents} of that property
* <li>Changing the cardinality of a data type to be more restrictive (e.g. changing an
* {@link android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_OPTIONAL
* OPTIONAL} property into a
* {@link android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_REQUIRED
* REQUIRED} property).
* <li>Adding a
* {@link android.app.appsearch.AppSearchSchema.PropertyConfig#CARDINALITY_REQUIRED
* REQUIRED} property.
* </ul>

* <p>If you need to make non-backwards-compatible changes as described above, you may set the
* {@code force} parameter to {@code true}. In this case, all documents which are not compatible
* with the new schema will be deleted.
*
* <p>This operation is performed asynchronously. On success, the provided callback will be
* called with {@code null}. On failure, the provided callback will be called with a
