Steps to Create Digi Locker Project using Android<\/h3>\n
Following are the steps for developing the Android Digi Locker Project:<\/p>\n
Step 1:<\/strong> Creating the android project using java as the language and adding the firebase library using the inbuilt firebase library assistant in the Android Studio.<\/p>\n Step 2:<\/strong> Creating Login layout:<\/strong> This layout will help the users to login into the Digi locker. It will also allow users to reset their password if they forget their password.<\/p>\n activity_login.xml<\/strong><\/p>\n Login.java<\/strong><\/p>\n Step 3:<\/strong> Creating Registration Form Layout to register new users to the Digi locker. It will also verify user accounts through OTP.<\/p>\n activity_register.xml<\/strong><\/p>\n RegisterActivity.java<\/strong><\/p>\n Step 4:<\/strong> Creating Main Page Layout. It will allow the users to upload new documents and files to the firebase. Users can select the file using the file dialog. On the basis of the file type choosen an icon will be displayed on the screen. After selecting the file users can upload the file by clicking on the upload button to upload the file.<\/p>\n activity_main.xml<\/strong><\/p>\n MainActivity.java<\/strong><\/p>\n Step 5:<\/strong> Creating Download files Page Layout to view list of files uploaded by the user. It will show the name of the file and an icon, based on file type. From this page users can download and delete the uploaded files.<\/p>\n activity_download_files.xml<\/strong><\/p>\n DownloadFiles.java<\/strong><\/p>\n DownModel.java<\/strong><\/p>\n Step 6:<\/strong> Creating layout for the list in the Download Files page layout.<\/p>\n elements.xml<\/strong><\/p>\n MyViewholder.java<\/strong><\/p>\n MyAdapter:java<\/strong><\/p>\n Now the app is complete and ready to be used<\/p>\n Congratulations, you have successfully created a digital locker Android app that allows users to securely upload and download files to and from Firebase storage. You can now customize the app to add more features according to your needs, such as file sharing, file encryption, and more.<\/p>\n This project has given you a basic understanding of how to integrate Firebase storage in Android apps and build a functional digital locker app.<\/p>\n","protected":false},"excerpt":{"rendered":" In this project, we will be creating an Android Digi Locker app that allows users to securely save their documents and files on Firebase storage and download them when needed.
