Hello @frannois, thank you for reporting bug. I will try to reproduce and get back to you

@frannois It sounds like you've declared Flipper as a debugImplementation dependency. If you do this, you cannot reference any Flipper code in your release builds. This is by design as Flipper code should never be bundled into your production builds.

[frannois]

@passy I am not talking about building my application with Flipper.
I am talking about building the flipper github project.

[frannois]

Last night master github project was failing for another reason, native though.

[passy]

Thanks for the clarification! Will give that a try.

Now I feel really stupid. Sorry, you're completely right. We must have broken this quite a while ago. Fix for it is coming and I'll make sure to add a CI job for preventing this from happening again. Thanks for the report!

Hi, @passy and @frannois I am facing the same issue after upgrading it to "react-native": "^0.62.2" It works in debug but in a release, it shows same as mentioned by @frannois. After Commenting on a flipper class while creating a build but when I use debug I have to uncomment to use a flipper. It is a wrong practice to comment and uncomment code. Kindly Suggest any solution for this.

I have the same problem. After upgrade to RN 0.62.2 I cannot build the app in release mode.

ReactNativeFlipper.java:10: error: package com.facebook.flipper.android does not exist import com.facebook.flipper.android.AndroidFlipperClient;

Ah, I had to move ReactNativeFlipper file to debug folder from main.
