I dont understand?
I mean the circularProgress from userinterface area.

It means you can't show what you want between screen changes.

You might be able to show file loading and web access progress initiated from screen initialization, though.

5

Perhaps an intermediate screen that shows the circularProgrees, and that accepts a startValue of which screen to go to next?

6

Wait, did you mean Screen changes, or screen changes?

7

when i go from screen1 to screen2 with open another screen. There is a black gap.

I don't know the architecture of your app, but typically we suggest to use Virtual Screen instead of many Screens.
By digging the forum you'll find a lot of topics on the matter.

Combining the virtual screen approach with fading effects by using the Phase extension from @shreyash you can switch between (virtual) screens without black screen in between.
The annexed .aia is a little example.

Use arrangements as screens. one hides, another visible. You can also apply animations to arrangements using an extension. Hope you will like this solution.

Thats what i am already do. But if i should have the whole app in 1 screen, it will be to large. Its around 4 screens for now. There is around 12000 blocks in thee whole app, and that will app inventor not work with in one screen.

Why so many?

I have not learned to reuse the blocks yet.
Sorry my bad english:-)
But now i build this app, and after that i will rebuild it to reuse the blocks and design.
I just have to find out how.

  • Reduce your block count:
    • Use parametrized procedures for common code
    • Use Media text files instead of big clumps of text blocks
    • Use generic blocks instead of repeating component event blocks
    • Encode repeating decision patterns into lookup tables loaded from Media csv text files (does your blocks image look like a box of combs?)
    • You don't need a component for every data instance. Reuse those components.
    • If you can't fit data into a ListView or List Picker, show a small subset of the data in an Arrangement and slide it across the larger list of data.
