Happy New Year Guys...im really loving this platform on a daily basis.i'll be completing my Bsc in IT with speciality in Software Engineering.Mobile computing is one of the course im doing this my final semester(semester-8),and we implementing it using JAVA(Android Studio).Building an app using java is really tough especially for beginners.i was really happy,and still happy when i came accross this platform(MIT App Inventor),that makes complex things very easy.To the point,i got a sidebar somewhere on the internet but it keeps crashing my app.Can someone recommend somewhere i can get a safe one?Thanks guys...
This is one of the best, featureful, and most reliable sidebar extensions I have used:

Upload your AIA, someone can take a look
You do not appear to have created any sidebar list items?
Revisit Ulli's page and read the documentation of how you can do this.

I also note that you are not switching screens correctly, this can lead to errors and app crashes.
Use different screens wisely
- Before starting to create another screen, first you should think about is it really necessary?
- See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed...
- See also Martyn_HK's example about how to use Tabs in App Inventor and another example from Cyd. and my Tabbed Screens Demo
If you decided to use different screens, then you should switch them correctly, else you will run out of memory after a while...
