Android Proguard issue #2457
Comments
We will need a repo project to look at your configuration. |
@yatespeter100 @jitendrajadav do you have a repro by chance? I have a couple projects that I use proguard with in release mode and they are working fine for me on version 2.5.1 of Xam Forms. @jitendrajadav in your case that looks like something going on with a particular 3rd party library you are using @yatespeter100 I'm guessing there's probably something either getting linked out or processed by pro guard that your app needs. If you enable diagnostic build output you can see in there where Java will give a bunch of ProGuard warnings. The other thing you can do is check logcat. Usually those NullReferenceExceptions will say some class is missing and then you can just add it to your proguard file Here's the proguard.cfg file I'm using

@PureWeen Thanks I will try and take a look over the weekend and let you know what I find. |
@PureWeen So I have looked at the other tickets created. I am able to find my proguard_xamarin file in the obj folder of the Android project. I have tried adding some lines to the cfg file there but they get overridden in build. Am I doing something wrong? I don't see a proguard file at the root of my Android project. I only have it enabled for release and not debuug. Any tips much appreciated |
this talks about adding the proguard file https://docs.microsoft.com/en-us/xamarin/android/deploy-test/release-prep/proguard?tabs=vswin it's pretty easy the only caveat is if you're on windows to be sure to read this part |
@PureWeen Ok looks like your suggestions worked. The only lines I had to add to the custom cfg file were |
