flipper | :dolphin: Beautiful, performant feature flags for Ruby | Access Management library

When enabling hermes in the Podfile and rebuilding the build it fails due to RCT-Folly. No idea what it does.

To re-initialise everything I use the following:

rm -rf node_modules && rm package-lock.json && npm install && cd ios && rm -rf Pods && rm Podfile.lock && pod deintegrate && pod setup && pod install && cd ..

I also start the metro bundler with:

npx react-native --reset-cache

Anyone has a solution?

The app uses react-native v0.64 and we want to have a better performance using hermes.

ios/Podfile

Using Firebase Analytics in an ios app, on a phone and simulator using ios 15.4, XCode 13.2.1 (13C100) in a React Native app. The app itself works, but when I try to add unit tests, the test runner fails with the unrecognized selector problem. I have combed the issues on SO, they either ask for more info and die on the vine, or reference the same four issues on Firebase's github.

The Podfile (below) doesn't have use_frameworks! so it's unlikely that duplicate symbols are the culprit. I tried the one concrete piece of advice from the github issues, pod deintegrate and recreate Podfile.lock, to no avail.

Here is the crash log, and below is the Podfile:

I have a react-native app that runs perfectly well in debug, but fails on a release build. Running node 16.3.2 inside Windows 11 with react-native 0.63.4

Any thoughts on what to try would be greatly appreciated.

The build error from gradlew assembleRelease is:

I have several HTML elements that represent tiles to be flipped on click. Each element has a container div, which holds two divs, one for the front and back of the tile.

I recently upgraded to xcode13, before which react native app was working fine for long time. However, after switching when I run in iOS, I am getting error "instruments is not a developer tool or in PATH" on command "xcrun instruments". I tried following commands (all with Xcode in quit status)

I'm a beginner at coding (so forgive me if this problem has an easily solvable solution), but I'm trying to create a color flipper that changes the background of a webpage each time to a random color when the "generate" button is clicked. I couldn't figure out how to configure the button, so I checked a tutorial on how to do so. The code between the tutorial and my version is the same, but after I click "generate" on the webpage once, it never changes the background again. Below is the code for the button:

I have generated a .apk file out of React Native 0.66.3 app (RN app) for test distribution by 3rd party distribution channel which only accept .apk format. After downloading to an android phone (API 30), the app is stuck with the registration page after entering user info and didn't go any further (after user enters reg info, the RN app shall route to verification page and send the user info to backend Nodejs server). The RN app is working fine on both emulator (API 27) and running on the same Android phone (API 30, connected with USB cable). The Android Studio used is 2021.3.1. The develop platform is macOS Big Sur.

I have no clue what is the problem. Here is the steps generating app distributed:

1. Generate app-release.aab file. Under /android do:

I am struggling to get my GIFs to animate on the Android version of my RN application. The iOS version is animating the looping GIFs as expected but I only see a stuck "single frame" image from the GIF on the Android device.

According to the debugging and RN-documentation it's required to add a few lines of implementation to the dependencies within the /android/app/build.gradle, but even after cleaning the gradle (running ./gradlew clean in the /android folder) and deleting the cache of the RN app (running react-native start --reset-cache in the project root folder), I do not see any difference in my application.

I have googled and tried a lot. Based on my debugging adventure, I have tried and double-checked these suggestions, that seems to work for others but it doesn't seem to work for me...

• I have tried several versions of the fresco-libraries that seems to be required and I have also tried placing the lines in both the bottom as well as the top of the dependencies.
• Some answers also suggest to add one or more lines of code to the android/app/proguard-rules.pro but this doesn't change anything either.
• I use GIFs in different ways of my application but it always has width and height included to the style property on the .
• I have tried with GIF-uris from different CDNs and domains.
• Reinstalled the app on my test devices.
• Closed and reopened my code editors.

I'm using the following versions:

• Java: 11.0.12
• React Native: 0.65
• Android SDK: 30.0.2
• npm: 6.14.4

This is my full /android/app/build.gradle:

When I try to build my react-native project in Xcode I get this error from RCT-Folly:

{path}/App/ios/Pods/RCT-Folly/folly/container/detail/F14Table.cpp:41:10: Thread-local storage is not supported for the current target

{path}/App/ios/Pods/RCT-Folly/folly/container/detail/F14Table.cpp:56:10: Thread-local storage is not supported for the current target

I'm not really sure what is going on so im not sure what information I need to provide but here is my Podfile:
