database application with password to go offline

it can take up to a month for the project, I was unable to edit the days. I need an Android app. I would like it to be designed and built. * after the application is opened for the first time, a login screen should appear, the application must request an access code, this code is registered in a database with several codes, the user can insert any code that is in the data database, the application does not need to log into the user's account, login is only to find out if the user is allowed to access the application * after the user goes through the login system, he no longer needs to write the security key until the key expires, it can be 1 month or 2, for example * after entering the main page and the user should see 2 things, a photo gallery and a button to search the photos by name * this gallery works like this, there is a database within the application, the same database of keys to enter the application, it contains the name of all the photos, a corresponding image URL for each photo and a video URL corresponding to the name and image. * the user does not need to see the image name * all images are on the internet, because as I said, they are just URL of the database, * when the user clicks on the image he is directed to the video URL, the video must not open in the user's browser, the video must open in any video player that the user has installed. if the user has 2 video playback applications, he must ask which user he wants to watch, I will give an example, when you open an image. Android asks if you want to open the image in the Google photo app or the gallery app. this is an example. in this case, Android should ask which application to watch the videos the user wants to see the video. * as mentioned above, there is a system to search for the photo by the name of the image, just like Netflix for example, * the database containing, access keys, image names, image URLs, video URLs, all data comes in a Microsoft access file * this data file must be imbued within the application, the application cannot make any queries on the internet, none, the application goes on the internet just to show the images, only the images, everything in the application cannot depend on any type of help external, like Google Firebase for example, all data must be obtained from the data file. * I, the administrator must be able to create a new data file on my computer using Microsoft Access, open Android Studio, replace the old file with the new one, generate a new APK file to be posted on the Play Store, so the list data can be updated,
