77.5 Creating a New Storage File

When the New button is selected, the application will need to trigger an ACTION_CREATE_DOCUMENT intent configured to create a file with a plain-text MIME type. When the user interface was designed, the New button was configured to call a method named newFile(). It is within this method that the appropriate intent needs to be launched.

import androidx.appcompat.app.AppCompatActivity

import android.os.Bundle

import android.view.View

    private val OPEN_REQUEST_CODE = 41

    private val SAVE_REQUEST_CODE = 42

.

.

    fun newFile...
