Unable to store data.

The application can only use the system manager for data storage. I deleted the system file manager, and the third-party file manager used cannot operate.

I hope the application can call the third-party file management or bring its own file manager for data storage.

Start by reproducing data storage with the system file manager deleted and a third-party file manager installed, using the attached screenshot as context. Review the application's Android storage entry point and determine how it currently selects a manager; done means storage works through a third-party manager or an included file manager.
