Android Question MultiPhotoPicker crashes when "Pick Photos" button is tapped.

[rleiman]

Greetings,

I compiled and ran the sample app that comes with the MultiPhotoPicker library. When tapping the "Pick Photos" button the app crashes.

Here's a dump of the logs.

All help will be appreciated.

Thanks.

Did you run the example as is?

I ran the example and it is working here.

Did you run the jetifier tool?

Hi Don,

Yes, I ran it but it looks like it won't work on a Samsung S9. Later I will try it on another phone.

 

[DonManfred]

I ran it on Samsung Note8 (Android 9)...

I'm also on Android 9. I will test it out on a Ulefone Helio P70 phone later. If it does the same thing, then I know something may be wrong with how my B4A is set up.

Based on the error message you aren't running the jetified version of that library. Make sure that the library is not in the internal libraries folder.

Hi Erel,

I checked the folders and everything looks ok. Could it be something else?

Thanks.

 

[Erel]

It is possible that the library is built in such way that it cannot be jetified.

I am using targetSDK 28
