How to Build Xamarin.Android with Crosslight Libraries

Hi Jimmy,

Here is how to fix it, please add the attached files in YourProject.Android, and change the build options of that files into LinkDescription

I also attach the screen shot. I think this is caused because we choose Link SDK assemblies only, it ignore the Linq files, however, we need to use Link SDK only to reduce size.

Hope that will helps!

Hi Arief,

That is actually the error "Unable to perform data operation". The second one was just the stack trace, which we displayed in order to get more information. I don't know which line of code the error occurs, but guessing on the stack trace, it's when the LoadDataCore() method is being invoked somewhere in the Navigated event of the DataListViewModelBase.

Hi Jimmy

Just want to update you, we successfully replicate your bug.

Could I know which line of code that problem happened, i mean in your second screenshot because the error seems different and the only error that i replicate is the unable to perform data operation one

Again, this error does not occur when running on Debug mode.

Hi Jimmy,

Ok, I will test it, I will try it using our Simple CRM/Sync Sample because, it was most complete.

I will get back to you when done testing.

Hi,

Here's what we followed, and currently using an Ad-Hoc deployment for staging release.

Hi Jimmy,

Our developer suspect this is a data error, which means what you must do is clean your bin or obj or make sure your App have access to your database.

However could you also show me your step by step how you do the release?

Hi,

How do we compile a release version with Crosslight binaries? The Release profile for our build was set to "Link SDK Assemblies Only" on Android Build setup. There are also calls to preserve SQLite, PushNotification, and Social Services but when released we are receiving an error with one of view models... see attached screenshot.

This error does not occur on debug mode, so am guessing this has something to do with how it was built for release.
