⚠️ Missing Environment Information
ℹ️ Your issue may be missing information about your development environment. You can obtain the missing information by running react-native info in a console.

Hi I have updated Question with Environment Information. It says Android SDK missing. But I have already installed it

[sunguoxing0628]

@RockinGarg i hope it helps you

1、open a terminal
2、touch ~/.bash_profile
3、open ~/.bash_profile
4、write

export ANDROID_HOME=/Users/yourname/Library/Android/sdk
export PATH=$ANDROID_HOME/tools:$PATH
export PATH=$ANDROID_HOME/platform-tools:$PATH

5、source ~/.bash_profile(if it doesn't work,next)
6、change "android": "react-native run-android" to "android": "source ~/.bash_profile&&react-native run-android", and run yarn android

[jwd2a]

Can confirm this bug. Started a new project last night and ran up against this. Tried again, and tried @sunguoxing0628's suggestions, but still getting this:

Environment details:

• MacOS 10.15.3

And just in case the react-native info output is helpful:

[sunguoxing0628]

@jwd2a
Before that, I used Android Studio to install the gradle and run the app. I don't know if it has any impact.

[RockinGarg]

yarn android

Hi @sunguoxing0628 none worked for me I tried your solutions

[RockinGarg]

For now I used Android Studio to Build App once. But it is still issue that it doesn't work with command Line

Hi,

• Shell: 5.7.1 - /bin/zsh
  Your shell is zsh, not bash. Therefore you need to source your .bash_profile in zshrc file.
  Just add the line below into ~/.zshrc
  source ~/.bash_profile
  Then restart your terminal or source your ~/.zshrc by using the code below
  source ~/.zshrc
  To check adb:
  adb --version

• error Failed to launch emulator. Reason: No emulators found as an output of emulator -list-avds.
  Open Android Studio AVD Manager, then create an emulator if you have no emulators.
  If you have emulators, then wipe their data and rerun
  npx react-native run-android

[RockinGarg]

Hi All
Attaching info again It says Android SDK: Not Found which looks like the main reason that it not letting me launch Emulator from react-native command
But I had already installed Android SDK and Android Studio Too

If I'm understanding correctly this works when running directly but not from the CLI? Did the last set of tips about your bash config help? Have you been able to get react-native doctor to run clean? Is that still giving the same failures?

[RockinGarg]

Hi yes you are right
I am to run in android through android studio
But not through CLI

Bash changes i made as suggested none worked

React-native doctor says
AndroidSDK: not found
But its installed

[developius]

This is happening for me too. It was all working fine yesterday, I could run my RN app on both iOS and Android.
Today however, I'm getting this error from Android when using npx react-native run-android:

java.lang.RuntimeException: Unable to instantiate application <my identifier>.MainApplication: java.lang.ClassNotFoundException: Didn't find class "<my identifier>.MainApplication"

Doing npx react-native doctor gives:

 ✓ Node.js
 ✓ yarn
 ✓ Watchman - Used for watching changes in the filesystem when in development mode

Android
 ✓ ANDROID_HOME
 ✖ Android SDK - Required for building and installing your app on Android
   - Versions found: N/A
   - Version supported: 28.0.3

iOS
 ✓ Xcode - Required for building and installing your app on iOS
 ✓ CocoaPods - Required for installing iOS dependencies
 ✓ ios-deploy - Required for installing your app on a physical device with the CLI

I followed the installation instructions to the T, and it was all working correctly yesterday. That suggests to me there's something up with the environment variables but I can't work out what it is. Here's my .bash_profile:

export ANDROID_HOME=$HOME/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

Running source ~/.bash_profile && npx react-native doctor gives the same output as above.

[developius]

Update: running this appears to fix the issue. No idea why.

cd android && ./gradlew clean

[RockinGarg]

@gokhandoslu It works great for me! Thanks a lot.

@RockinGarg There were plenty of errors/warnings in that log to follow up on. Did you end up getting unblocked?

[RockinGarg]

Hi I used Android Studio to manually install Build on Android Emulator then manually launch the App by running server.

I am still unable to use
react-native run-android (Doesn't Work)
whereas
react-native run-is (Works Perfect)

what are you doing here for be like this
i have the same initial issues

[developius]

@Mhde96 @mylesshie @RockinGarg

Your logs include a message about missing adb (/bin/sh: adb: command not found). I would suggest making sure adb is installed before trying to debug anything else. Also, react-native doctor is your friend.

[diegoserranor]

Hello, I am experiencing a similar issue in my macOS + Android Studio setup when running react-native run-android from the command line.

The only way I can get it to work is by building the project from Android Studio. Also:

• I tried ./gradlew clean in the ./android folder but that alone fails as well.

• I have checked my .zshrc setup a few times. I even hardcoded $ANDROID_HOME to the path found in Android Studio's settings.

This is occurring with the 0.63.3 release. Could someone please advise?

This is the error:

FAILURE: Build failed with an exception.

* What went wrong:
Could not initialize class org.codehaus.groovy.runtime.InvokerHelper

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

* Get more help at https://help.gradle.org

I am facing the same issue.
Wow, this is open for a long time.

[diegoserranor]

Setting up a $JAVA_HOME variable to point to the adoptopenjdk11 I installed through homebrew helped with this issue.
In my case, it seemed like a past JRE/JDK installation was interfering. I can also run gradlew commands now.

Would be helpful to mention adding $JAVA_HOME in the docs.

Hi can you share your full bash_profile or where have you set java_home variable

[diegoserranor]

@RockinGarg I use zsh. This is my .zshrc configuration for react-native:

export JAVA_HOME_8=$(/usr/libexec/java_home -v1.8)
export JAVA_HOME_11=$(/usr/libexec/java_home -v11)
export JAVA_HOME=$JAVA_HOME_11

export ANDROID_HOME=/Users/diegoserrano/Library/Android/sdk
export PATH=$PATH:$ANDROID_HOME/emulator
export PATH=$PATH:$ANDROID_HOME/tools
export PATH=$PATH:$ANDROID_HOME/tools/bin
export PATH=$PATH:$ANDROID_HOME/platform-tools

[campsjos]

In my case I had to install Android SDK Command-line Tools (in SDK Manager > SDK Tools) in order to react-native doctor recognise Android SDK

[sakkaras]

This link(https://stackoverflow.com/questions/35000729/android-studio-could-not-initialize-class-org-codehaus-groovy-runtime-invokerhel) and @campsjos's comment helped me to fix the issues for run-android command.

[RockinGarg]

I would like to close this issue
It’s been long i am working on react native and found this command fails sometimes and sometimes that’s work it’s intermittent.
If app is already installed then this command works fine else it fails

If anyone think this issue is occurring feel free to open

My observation
Call
source ~./bash_profile before you run
react-native run-android command

This makes it works sometimes
