Install React Native Cli And Run Your Projects On Your Android Phone

This "tutorial" assumes you already have the Android SDK installed.

To install react native on linux you must have node and npm installed.

Let's start:

Update your PC with

$ sudo apt update

Install open jdk

Do this using the following on the command line

$ sudo apt install openjdk-8-jdk

Install react Native CLI

Assuming you have node installed, the next step is to install the react native CLI. To do this, run the following code on your command line.

  $ npm install -g react-native-cli

Add Android home environmental variables

If you're using bash as your shell, go to $HOME/.bash_profile or $HOME/.bashrc config file and add the following lines

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

If you're using ZSH, it should be $HOME/.zshrc

To open $HOME/.bashrc, go to the terminal and type

 $ nano .bashrc

Scroll to the bottom and add these lines of code at the last line

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

When done, Press ctrl + s to save and ctrl + x to exit.

Next load the config file into your shell by typing the following on the command line

$ source $HOME/.bashrc

Comfirm that ANDROID_HOME has been added to your path by typing

$ echo $PATH

You should get this on your screen

/home/user/.nvm/versions/node/v10.16.3/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin:/home/chidera/Android/Sdk/emulator:/home/chidera/Android/Sdk/tools:/home/chidera/Android/Sdk/tools/bin:/home/chidera/Android/Sdk/platform-tools

Create a React Native App

If you got to this point, congrats. Next let's create a react native app on the desktop or any directory of your choice

Desktop$ react-native init reactNativeProject

Run the react native app

First cd into your project

Desktop $ cd reactNativeProject

The next thing is to

enable USB debugging on your phone, and
connect your phone to your PC, then run

$ react-native run-android

Start the project

After running

$ react-native run-android

the final thing is to run

$ yarn start

This will start the project.
