Setting up React Native

This procedure is the details procedure as defined in the React Native Getting Started

To install react native you need to make sure you have:

Initial setup

nodeJS

   curl -sL https://deb.nodesource.com/setup_4.x | sudo -E bash -
   sudo apt-get install -y nodejs
   sudo apt-get install -y build-essential

This will also install the npm, the Node.js package manager.

JAVA Download Java JDK, we choose Java SE Development Kit 8u102 java 64x. Open the new folder (java) location and extract to /opt this way
```
 sudo tar -xvf ~/Downloads/jdk-8u102-linux-x64.tar.gz
 sudo unzip ~/Downloads/jdk1.8.0_102 -d /opt
```
Android SDK and Android Studio Download the [Android SDK] (https://developer.android.com/studio/index.html) and extract it to the new folder:
```
  sudo unzip ~/Downloads/android-studio-ide-143.2915827-linux.zip -d /opt
```

Add to the PATH Java and Android by editing the ~/.zshrc

  PATH="/opt/java/jdk1.8.0_102/bin:/opt/google/android-studio/bin:~/Android/Sdk/tools/:~/Android/Sdk/platform-tools/:$PATH"

and from the shell:

    source .zshrc    
    rehash

And check your path typing:

    which java
    which studio.sh
    which android

....

You will need to have the C++ runtime library so

 sudo apt-get install lib32stdc++6
 exec studio.sh

To use AVD (Android virtual Device) to simulate a device, you need the KVM virtualization tool that requires the Processor to be configured for virtualization. From the BOIS (FnF2 on the Lenovo Ideapads), go to configuration and change intel virtual technology to enable

New you can launch your emulator by running the emulator command

   npm install -g react-nativ-cli
   react-native init AweSomeProject
   cd AweSomeProject

You will encounter several errors with missing SDK components such as

Google API 23.1: Add it directly from the Android Studio and select Tool|systemSetting|AndroidSDK and check the Show Package Details checkbox. Then add Google API for API 23 (Marshmallow) and Apply

(IMAGE!) -- ADD PICTURE ---

You may encounter additional errors about Build Tools missing and then do
```
      android list sdk -a
```

look in the list and find this lines:

check what their numbers to type:

 - android update sdk -a -u -t 8

Then you may encounter a bug with libz.so, to solve this
```
 sudo apt-get install lib32z1
```

Now you should be ok to run your React Native application!!!

 cd Awesomeproject
 emulator -avd <your emulator name>
 react-native run-android

Knowledge is hope
