Thanks !

Would you mind if I recommend you add androidx to this list?

AndroidX

-dontwarn com.google.android.material.**
-keep class com.google.android.material.** { *; }

-dontwarn androidx.**
-keep class androidx.** { ; }
-keep interface androidx.* { *; }

@ThanawatMas did you test it on production? (we have been using androidx+material components without any proguard settings for long time)

Is this proguard still valid? We should keep this updated! Thank you

Awesome! Thanks, @jemshit. Although, my app still crashes on Le Eco 2 devices.

Good one bud, it will be grateful for developers if you keep updating the file as and when you work on some other library.

@jemshit kindly add the following lines for Gson to prevent proguard from obfuscating field's serialize name mark with @SerializedName annotation.

# Prevent R8 from leaving Data object members always null
-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

Hi This is Jesuraj.

I have a android.webkit.WebView in my activity. When the proguard is enabled in gradle file, In release build the Webview activity is not working.. Please guide me how to fix this issue..
