Hey there, I’ve run into similar headaches with Rg.Plugins.Popup in Release builds before—totally get how frustrating this is! Let’s walk through some common fixes that should get your APK working properly:

• Adjust Linker Settings
  Release builds often use aggressive linker optimizations that accidentally strip critical code from the plugin. Head to your Android project’s properties, go to the Android Options tab, and change the Linking setting to Sdk Only (instead of Sdk and User Assemblies). If that resolves the issue, you can refine it further by adding a linker config file to explicitly keep the plugin’s assemblies:

  <linker>
    <assembly fullname="Rg.Plugins.Popup" />
    <assembly fullname="Rg.Plugins.Popup.Animations" />
    <assembly fullname="Rg.Plugins.Popup.Services" />
  </linker>
  

  Save this as Linker.xml in your Android project and set its build action to LinkDescription.

• Update ProGuard/R8 Rules
  If you’re using ProGuard or R8 for code shrinking, they might be obfuscating or removing key parts of the plugin. Add these rules to your proguard.cfg file:

  -keep class rg.plugins.popup.** { *; }
  -keep class rg.plugins.popup.animations.** { *; }
  -keep class rg.plugins.popup.services.** { *; }
  

  This tells the shrinker to leave all Rg.Plugins.Popup-related classes untouched.

• Double-Check Initialization
  Sometimes Release builds optimize out initialization code if it’s not explicitly called. Make sure you have this line in your Android MainActivity’s OnCreate method, before loading your main page:

  Rg.Plugins.Popup.Popup.Init(this);
  

• Clean and Rebuild from Scratch
  Cached build artifacts can cause weird inconsistencies between Debug and Release. Try cleaning your solution, deleting the bin and obj folders for all projects, then doing a full Release rebuild before generating the APK.

• Test with a Minimal Project
  If none of the above works, create a tiny test project with just the plugin and a simple popup. If that works in a Release APK, the issue is likely tied to conflicting plugins or custom code in your main project that’s interfering with the popup system.

Since you mentioned your IDE’s Release mode started working but the APK still fails, the problem is almost certainly related to packaging optimizations—so linker or ProGuard settings are your best bet to fix this.
