- In this video, we will be building a simple android application in which we'll add User Authentication and perform CRUD Operations with Firebase Realtime Database in Android. The Firebase Realtime Database is a Cloud-hosted database, i.e. it runs on a cloud, and access to the user is provided as a service. All the users connected to it can get access to the data in Real-Time. So, let's get started now.

@@Mohit-il9gx My app also crashes when update button is clicked, How can I fix that?
The app crash when performing update operations
Can register and log in fine. But when I go to add a course, the progress circle just keeps spinning and nothing shows on my database. Any ideas? Thanks
same
Same. Did you solve the problem?
Is the CRUD functionalities in Firebase Android Studio meant for only one user? Because in my final year project, I made CRUD functions but when I switch users the saved entries are carried over.
Anyone know how to fix this so that only CRUD data saved by a user is shown?
If it's possible.
If someone knows what I'm talking about, please let me know. Because if I log in with different users, past CRUD entries saved in other user sessions always show up in it. Or is it a matter of changing the database rules.
@@eoghanfeighery7383 I had this thought before, and it was a simple fix. All you have to do is create a separate node in the database tree pertaining to the data you want to hold, and have each child node of said node be the userid of whatever user is signed in, then you should be able to save the data according to whatever user is signed in specifically.
@@johnperez3579 Yeah I actually found a good tutorial that used Firestore for the node thing you mentioned. I tried to see if I could find a tutorial that used RealTime Database but I couldn't find one. Probably hasn't been documented enough yet.

source code ?
i have some grave issues my APP CRASHES sometimes when I click on update courses button can anyone please resolve my issue i really need this please
It is probably because something is wrong with the xml page. For example look at the logcat and go to the highlighted blue activity and then look above it to see the reason why. For me it was because there was something wrong with the textinput ...
@@tacozzitv7640 how did you solve it ?
@@youtubevance3273 When the app crashes, go to the bottom menu where it says logcat. When in logcat, find the highlighted class and see where it points the error

if we delete a course immediately after adding a course, it does not delete it. the course re-appears. why is that?
