Hope you could help me here:
I'm currently building an app which I created through CRNA and then ejected. I get the ios version right on but I'm currently struggling a lot with the android version.
When running react-native run-android all I can get is the following error:
Error type 3
Error: Activity class {com.myapp/com.myapp.MainActivity} does not exist.
I've checked app/build.gradle, app/src/main/AndroidManifest.xml, app/src/main/java/com/myapp/MainActivity.java and app/src/main/java/com/myapp/MainActivity.java for name errors on package. I've tried moving from com.myapp to com.mebius.myapp and com aswell.
Seems this comes from the only plugin I'm using. I'm keeping on the investigation
Any hints?
There are 3 possible reasons for the android app build fails to make
1. You need to define sdk path in android/local.properties
if local.properties doesn't place then make a file names with that
add
sdk.dir = home/user/AndroidApp/local/Sdk
You can match with their system path..
2. Your genymotion or avd must enable with the android studio
3. You must have to go with the following command
npm start
in new terminal .
Please go through with it.
Thanks
Actually I had a problem with my gradle config which look like:
include ':react-native-sensors'
project(':react-native-sensors').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-sensors/android')
rootProject.name = 'accelapp'
I needed to add: include ':app'
I don't know if it's due to the process of ejecting from CRNA or if it's due to react-native link react-native-sensors though.
EDIT After some investigation, I couldn't reproduce this issue. This leads me to say it was a faulty copy/paste...

I'm really struggling with what seems like a very primitive error. I have installed react-native-config and when console.logging the Config object it returns {}.
The problem occurs both on android and iOS and it doesn't seem to be a linking issue because (even though RN 71.3 doesn't require manual linking) when following the steps to link manually on android I got an error saying RNCConfigPackage already linked.
This is a simplified version of my code:
import Config from 'react-native-config';
console.log(Config);
And this is what my .env file looks like:
REACT_APP_STAGE=development
TEST=ThisIsATest
ANOTHER_TEST=ThisIsAnotherTest
Debugging attempts
I have already tried:
Running gradlew clean and pod install (even though it's not a platform specific issue)
Run with ENVFILE=.env react-native run-android to hard code the env file
I understand that this is very limited information in order to debug the issue but any direction and help is appreciated including any approach you would follow to debug.
EDIT: The Config appeared in the end but is very late to update, an issue more people seem to be facing, I have used react-native-dotenv instead.
Our bundle entry point is at src/index.tsx, which appears not to match the Sentry default of ./index.js.
Sentry is failing on sentry-cli react-native-xcode with the error EOF while parsing a value at line 1 column 0.
Using debug log level, I see:
+ ENTRY_FILE=index.js
...
Error: The resource `/Users/lukecwilliams/Projects/mobile2mr/index.js` was not found.
And in the actual CLI command, this is being run: --entry-file index.js
We need instead --entry-file src/index.tsx. How can we customize this? I can't find an answer in the docs or source code.
I've found this solution (custom build script) but it's still not working.
I have a script in the project root:
sentry-cli-xcode-build.sh:
./node_modules/react-native/packager/react-native-xcode.sh ./src/index.tsx
And in the build command in project.pbxproj:
shellScript = "export SENTRY_PROPERTIES=sentry.properties\nexport EXTRA_PACKAGER_ARGS=\"--sourcemap-output $DERIVED_FILE_DIR/main.jsbundle.map\"\nexport NODE_BINARY=node\n../node_modules/#sentry/cli/bin/sentry-cli react-native xcode ../sentry-cli-xcode-build.sh";
But the result is a fairly ambiguous: error: Permission denied (os error 13)
Do I need to change the directory setup somehow? I don't see a concrete example in Sentry docs or the GH answer above regarding where to put the script and how to reference it exactly.
It turns out that this build step should simply be disabled in iOS projects using Bitcode (which is the default). So, we have no more need to run a custom build script.
We'll use Fastlane afterward to upload debug symbols.
Docs for reference:: https://docs.sentry.io/platforms/react-native/#ios-specifics
The answer is
export ENTRY_FILE=index.ios.js
in the script
I'm not sure what exactly is happening but I am unable to run react-native link without errors occuring

This randomly started happening after attempting to npm install react-native-firebase.
What I've tried
clear-caches
remove node_modules and npm install
Checking out my code back to a previous commit
Adding my package name to the manifest locaed in /android/app/src/debug/AndroidManifest.xml
Removing the app from my computer and cloning it from github
Running react-native link on another project, which works, but i just can't run react-native link on this specific project.
So the answer to my question was that in my android manifest xml file, there was an incorrect closing brace for one of my intent filters.
So for anyone that this happens to ensure that all of your Android files have correct syntax.
I fixed this problem by closing some unclosed tag in android/app/src/main/androidManifest.xml. Try checking the file line by line.
I keep receiving this error when running my App.js for React Native that was working perfectly well before I attempted installing Victory charts. Somehow something broke and after over three hours of work I am unable to figure out a solution. I have tried everything I could find on the web including uninstalling watchman, reinstalling watchman, reverting to React Native 0.55.4, some other recommended commands. Nothing is working.I am so confused.
$ yarn add react-native-scripts
This helped.
I think the other library may hurt the installation part of your package. To solve this issue on IOS you need to add its library like below:
First do 'yarn add react-native-scripts'. In the case that it dose't work continue other steps.
1-Go to the node module of your project and find the package folder and find the ios file inside it.
2- Then drag it into ‘library’ section of your xcode. (It is the subset of your project folders)
3- Then go to ‘build phase’ and in the ‘Link binary with libraries’ add it there by clicking on the plus sign
4- Then in some cases you need to add the correct path of the ios file inside your node module in the xcode. To do that you should go to ‘build setting’ section in the xcode and search header there. Then you need to add the path there below other paths.
5- Then clear everything (cmd+shift+k) and then finally compile it.
I hope it works for you.
In my case the "crna-entry.js" file does exist in the roots and my project should work (nothing have been modified from last time when it does work).
After hours searching, finally I figured out the reason:
the packager's directory checking is case-sensitive and in windows terminal the drive "c:/" will not be auto-corrected to "C:/" which will lead to error.
Hope this will help someone who gets the same error.
Below is the full error message:
The development server returned response error code:404 Cannot find
entry file node_modules/react-native-scripts/build/bin/crna-entry.js
in any of the roots:
I recently wanted to reset a react-native project to most recent version, and so I initialised the seed project - "AwesomeProject"... The problem is that it comes with 19 flowtype errors "out of the box"

I am reluctant to make changes to these files as it may create knock on effects. Does anyone have a work around?
In general, whenever you want flow to ignore a file, you can just specify that file under the [ignore] section of your .flowconfig.
That said, I just react-native init'd a project, using react-native-cli 1.0.0 and react-native 0.29.1, and ran a flow server on the root of my project, and didn't get any errors.
