Hi @AbhishekChourasia16690，from this failed log image, It looks like your MacOS Android sdk environment is not ready:

1. Configure the ANDROID_HOME environment variable, The React Native tools require some environment variables to be set up in order to build apps with native code.

2. Add the following lines to your $HOME/.bash_profile or $HOME/.bashrc config file:

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

3. source $HOME/.bash_profile to load the config into your current shell.

Hello @kevin,
I executed the first step correctly.
But when I did the second step I failed coz once I created a new file in TextEdit and pasted the text as per you mentioned and tried pasting in home folder it didn't happen

Could you provide me links or mention steps how to perform second step
And please elaborate the 3 step you mentioned I couldn't understand much from whatever you written.

Waiting for your reply.

Thanks.

@AbhishekChourasia16690
check this doc => https://facebook.github.io/react-native/docs/getting-started
select MacOS and Android as Target OS.

[AbhishekChourasia16690]

Hello @kevin,
I checked the website you mentioned but I'm unable to see where I set Target.
Could you send screenshot if possible so its easier for me to find it out.

Thanks.

Hello @kevin,

Thanks for the screenshot.

I'm following the steps.

How to perform the second step you mentioned.

Waiting for your reply.

Thanks.

[AbhishekChourasia16690]

Hello @kevin,

Also they have mentioned in their website below line:

"If you have already installed Node on your system, make sure it is Node 8.3 or newer."

But the npm version I have is 6.9.0. When I tried updating the npm version its upgrading to only 6.11.3

Will this affect the working of React Native Android version.

Could you guide me through this too as well?

Waiting for your reply.

Thanks.

[0xinhua]

try using nvm or n to update your Node version.

[AbhishekChourasia16690]

Hello @kevin,

Do we have a .sln file kind of file for react-native project because whenever I try to open a project in Visual Studio it doesn't take import the entire react-native folder but just single file.

 

Please don't miss out answering the previous question too.

Thanks.
