API Model Conversion List

Certain APIs are available only in the FA model. To switch to the stage model, an adaptation is required. This topic lists these APIs and their substitutes in the stage model.

Context APIs

APIs Available in FA Model Only	Substitute API File in Stage Model	Substitute API in Stage Model
getOrCreateLocalDir(callback:AsyncCallback<string>):void; getOrCreateLocalDir():Promise<string>;	There is no corresponding API in the stage model.	Applications developed on the stage model do not have the operation permission in the application root directory. Therefore, no corresponding API is provided.
