Build failed and i dont know how to fix this

[Kelompok_3_A_2022_3]

please help me to fix this

[SteveJG]

Welcome.

The Build failed because of an AAPT error. AAPT errors occur for many reasons. Perhaps for one of these reasons:

You do not share your code Blocks so no one can even guess what your issue might be; sorry.

[Kelompok_3_A_2022_3]

how to share code blocks? can i share aia file? can you check for me?

• do you have more than 10 Screens in your Project?

• to download your Blocks image to your PC, go to Blocks screen; right click on a white area of the screen to see this dropdown.
  
  Then click Download Blocks as Image

[Kelompok_3_A_2022_3]

i have 30 page:( with aia file maybe?

[SteveJG]

The recommendation is not to use more than 10 Screens. Sometimes more can be used and then the developer has issues.

Are App Inventor Projects Limited to 10 Screens?

There isn't a hard limit on the number of Screens in an app. When used properly, multiple screens are a perfectly reasonable way to organize your app. For example, in a app for finding restaurants you may have a main screen with a map, a second screen that shows restaurant data, a third that shows menu contents, a forth that shows pictures of food, a fifth that shows reviews, etc. In this design each screen is a view over some model (cf. model-view-controller design pattern). The wrong way to u…

My guess is you get the error because of how you use your Screens or in your case number is a factor. Make a copy of your Project; remove a screen and try to recompile. Then do it all again until your projects run might find the problem.

@Kelompok_3_A_2022_3

pls check the file for me and give me solution plsssss

the solution is DRY - Don't repeat yourself... reuse your screens

General Tips and Tricks for App Inventor

This list was made by @Taifun 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...

i have 30 page

Your app has 41 (!) screens and all screens are switching incorrectly. However, the problem lies with the PERAWATAN_PAGE screen. I removed it and the app compiles. Here is the AIA (without 80 images, all removed from assets):
LansiApp2.aia (67.0 KB)

[Kelompok_3_A_2022_3]

Thank you for your help Anke. It means so much to me. I have a question. Does the asset you deleted have an impact on the build apk failure? because in the original file I tried to delete the screen PERAWATAN_PAGE but build apk remains erorr. its mean i must to delete the image too?

[PETER_PRO]

Share your blocks so that members can be able to troubleshoot the error.

I reduced all images using a batch command so that the app size is now only 3.4 MB (previously 24 MB): LansiApp_3.aia (3.2 MB)

No problem compiling the app (here):
