Android release build: Could not resolve reference to 'SQLitePCL.delegate_progress_handler'

[zoli13]

We updated in XF project the Android TargetSDK to 29 - which caused lots of "chain reaction", upgrading MvvmCross, Xamarin Forms, AndroidX, etc,etc. Finally, all worked fine, in debug mode.

But in release (AndroidLinkMode=SdkOnly), we have linker error:

Severity    Code    Description Project File    Line    Suppression State
Error       Java.Interop.Tools.Diagnostics.XamarinAndroidException: error XA2006: Could not resolve reference to 'SQLitePCL.delegate_progress_handler' (defined in assembly 'SQLitePCLRaw.provider.sqlcipher, Version=1.1.14.520, Culture=neutral, PublicKeyToken=7bbc99275c710061') with scope 'SQLitePCLRaw.core, Version=1.1.14.520, Culture=neutral, PublicKeyToken=1488e028ca7ab535'.

I tried to add LinkSkip <AndroidLinkSkip>SQLitePCLRaw.provider.sqlcipher;SQLitePCLRaw.provider.sqlcipher.android;SQLitePCLRaw.core</AndroidLinkSkip> Does not help.

These are the nuget packages of the solution.

What could cause this issue?

Not sure if this is the problem, but you have a mixture of SQLitePCLRaw 1.x and 2.x packages, which will definitely cause problems of some kind.

Thanks. And later I also found your other suggestion:

SQLitePCLRaw 2.x is compatible with sqlite-net-pcl 1.7. SQLitePCLRaw 1.x is compatible with sqlite-net-pcl 1.6.

So I downgraded all, and with this combination, it works fine (highlighted the changes)
