I can't debug my application.
First, the error happened when downloading the gradle, I managed to solve it, downloading manual and pointing to local file, but after that started to happen the error in other dependencies,
It's like I'm using proxy, but I'm not using proxy.
I've tried changing the version of gradle and all the other tips I've seen on the internet but nothing works.
I'm using the latest version of android studio on a macbook
the error message always relates to UnknownHostException.
So I tried implementing Facebook Login and followed all the steps accordingly. After having errors with FBSDKcorekit/FBSDKcorekit.h' file not found, I decided to pivot over to working on other components.
Lo' and behold, I have this error giving me trouble now. I followed along with this video: https://www.youtube.com/watch?v=rAXVKapP5cM&t=458s where I used the react-native install react-native-fbsdk and react-native link react-native-fbsdk commands in my terminal.
If it helps, I'm getting the following compile error in my terminal:
The following build commands failed:
CompileC /Users/someUser/desiredProject/ios/build/Build/Intermediates/RCTFBSDK.build/Debug-iphonesimulator/RCTFBSDK.build/Objects-normal/x86_64/RCTFBSDKGraphRequestManager.o RCTFBSDK/core/RCTFBSDKGraphRequestManager.m normal x86_64 objective-c com.apple.compilers.llvm.clang.1_0.compiler
(1 failure)
I'm not sure if it was the tinkering around with the react-native-fbsdk or making links to it that caused this error. Note my project was working before I was trying to implement Facebook Login and using the link command.
What's going on here?
Thanks in advance for your time and patience.
edit: Also I did not implement any of the Facebook login code yet since I couldn't get a successful build on Xcode.
#kdizzle Make sure you have the right packager running in the terminal, sometimes you may have a packager associated with another react native project running, this happens because when you stop running an xcode RN project, it doesn't stop the packager in the terminal, and when you start/open another RN project in xcode, it simply checks if a packager is running, doesn't check if it's associated with the current project. So make sure you stop all of the packager instances in the terminal and then open the RN project again.
This may happen when upgrading a project to a newer version of react-native. To fix it,
Stop your packager.
Quit your iOS/android simulator.
Reinstall your modules: rm -rf node_modules && npm install
Restart your packager and simulator, e.g. react-native run-ios
I had this issue and it happened when I changed Hardware within the simulator. To fix it I had to kill the packager and run 'react-native run-ios' again. It didn't happen all the time but when it did this fixed it for me!
Another use is in a Brownfield App. Check your iOS and/or Android react-native versions. If they don't match exactly you will see this error screen too.
For example: I had a react native instance running 0.45.1 while Android had 0.45.0 installed. The solution for me was to make sure everything was running the same version.
None of the above answers have worked for me, so I researched the 'react-native' options a little and ended up:
Deleting the iOS and android folders from the app directory altogether
Running 'react-native eject'
Re-running 'react-native run-ios'
After that the iPhone emulator seemed to have no problem with the app.
This problem would appear when React Native libraries in ios project can not found.
I happend to meet this problem when i update my react-native version from 0.42 to 0.44, and cause that a file named RCTConvert+Map disappear in 0.44, so i update my pod.
command: pod update
For debugging purposes, I run the application using xcode and the UI freezes. If I run the app independently, the application works fine.
Could piping of NSLog statements to the console cause my application to hang?
This bug has been fixed with the release of Xcode 4.4.1. See the following bug report for description:

I'm having a problem where cordova is failing to start the camera app on iOS. A simple case works fine, but in my app, not so much.
So I'd like to debug into the Cordova.framework to see what the problem is.
But I can't figure out how to do it. I've built the Cordova project that's sitting next to the installed framework, and I've replaced my framework reference in my project to point at it. That seems to be fine. But I can't step in or set breakpoints.
With the cordova project, i"m building UniversalFramework and it looks like it's set to debug in the scheme config, even though it always builds to release (this seems to be in the script), I see --DDEBUG in the clang output, so I think it's debug. I'm fairly new to xcode so I don't know if it's building a symbol file or how to verify it's a debug framework, etc.
Latest Cordova (2.0.0) has it like a seperate project and linked as static library.
Use that version, you can put breakpoints in the library code.
I am using eclipse for Android, once I check my application it works fine. I just go back to home and run it again after some change and it shows "Launching project: 27%" and stays there forever until I close IDE and kill its instance from task manager and restart it. I don't know whats the reason. I've been using it since 4 to 6 months but its happening recently a couple of days before...
Need help!
I also faced this issue..I just change my eclipse to latest version i.e eclipse juno and this solves my problem.
