My app keep crashing when i open the app

[mkarakaya6444 (m.k.)]

I do not use spinner

[Anu10 (Anu)]

Do you use anything from this ?

@Anu10

• Floating Action Button
• Radio Button
• Switch Component
• About Screen Title
• List View Filter Bar Hint
• Elements from String (Spinner)
• Audio, Contact, Date, Image, List, Phone Number, Time & Video Picker (Text Field)

or any component you are using having any empty text field ?

Which components you are using in Screen 1 ?

Are they having any empty text field ?

Did you checked your about screen title is empty or not ?

[dennis_littawe1542 (denlex.)]

[dennis_littawe1542 (denlex.)]

about screen title is not empty

[Anu10 (Anu)]

Which components using ? Those are extensions

[dennis_littawe1542 (denlex.)]

I have very many should I upload the aia file

[Anu10 (Anu)]

Previously in one of our post you uploaded aia but i was not able to upload it in creator may be due to many blocks (as my pc was not able to handle it) or many assets.

So can you upload it with just screen 1?

[dennis_littawe1542 (denlex.)]

yes i can do it but only afterwards i am not at home

[dennis_littawe1542 (denlex.)]

Is there also a possibility to create a new project and to take over everything so that it can be used as an update?

[Yash_Agarwal]

Now its working absolutely fine thanks for escalating my post @bodymindpower
Thanks @Boban for solving the issue.

The solution -
I just fill all the text fields in the labels and the switch.

Thanks

[dennis_littawe1542 (denlex.)]

I’ll try it out right away, what did you put in a text about?

[wild_an]

My spinner

My spinner error. How to fix it. Please help me

[Anu10 (Anu)]

@Anu10

Elements from String from Spinner should not be empty which also leads to the crash

Thanks to @dora_paz for reporting this

[wild_an]

Do I have to put them there?

[wild_an]

Like this?

[Anu10 (Anu)]

Yes but if you are using many spinner and don’t want to copy items one by one from blocks

So you can just enter spacebar in the Elements from String properties section it will not lead to crash.

[wild_an]

Its work.
Finally i can use my app again
this forum so helpful
thanks a lot.
