Hi ,
I am new to Xamarin Development. While i build xamarin application i get the following error.
Invalid ProGuard configuration file. Unknown option '-if' in line 16 of file 'C:\Users\LENOVO.nuget\packages\xamarin.androidx.fragment\1.2.5.4\buildTransitive\monoandroid90....\proguard\proguard.txt', included from argument number 26 at proguard.ConfigurationParser.parse(ConfigurationParser.java:217) at proguard.ProGuard.main(ProGuard.java:530)Picked up JAVA_TOOL_OPTIONS: -Dfile.encoding=UTF8
I actually set the code shrinker option as proguard and Dex compiler set as d8.
I dont know the reason why i got this error. How to resolve it.

Hi, MathanKumarM. Someone faced the similar issue, and it's solved by change the Code Shrinker to R8. Please try to test the option on your side.
Check the link: https://github.com/xamarin/AndroidX/issues/85

2021-05-05T07:09:32.797+00:00 Please check if the Android project file contains the
<EnableProguard>true</EnableProguard>or<AndroidLinkTool>proguard</AndroidLinkTool>setting. If so, please remove the line code.
