MediaStore.Images.Media.insertImage deprecated

SOLVED

The code suggested from @CommonsWare has no problem, except the fact that if you are programming with targetSdkVersion 29, you must add the condition:

val contentValues = ContentValues().apply {
            put(MediaStore.MediaColumns.DISPLAY_NAME, System.currentTimeMillis().toString())
            put(MediaStore.MediaColumns.MIME_TYPE, "image/jpeg")
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) { //this one
                put(MediaStore.MediaColumns.RELATIVE_PATH, relativeLocation)
                put(MediaStore.MediaColumns.IS_PENDING, 1)
            }
        }
