The problem is that you have misconfigured the environment variables  You have to use  in Windows  the SDK of  C  Users YOUR USERNAME AppData Local Android Sdk  For more information  https   facebook github io react-native docs getting-started  Select  React Native CLI Quickstart in the Android development environment section in point 3  Configure the ANDROID HOME environment variable  If you do it as you have it right now you must configure each project to use your environment variables and if the project is among several people with their equipment it can cause a problem  If you do it as I have told you  you will not have to configure any project

The best solution I can find is as follows     Download Android Studio and SDK of your choice  Even if you think you don t need it trust me that you would need it to release the apk file and some manual changes to the android code   File   New   Import   point to the location where your react native android project is   If it ask you to download any specific SDK then please download the same  It can ask you to update gradle etc    Please keep on updating where required   If you have an existing Android SDK and you know the version then all you have to do is match that version under build gradle of your android project    This is how the gradle file will look like      If everything has gone well with your machine setup and you can compile the project using the Android Studio then nothing will stop you to build your app through react-native cli build android command   With this approach  not only you will solve the problem of SDK  you will also resolve many issues related with your machine setup for Android development  The import will automatically find SDK location and create local properties  Hence you don t need to worry about manual interventions

Fixing SDK Path Errors on Linux Distributions    Your project is not finding the SDK set in the Project Settings via the path provided  so the project needs to be pointing in the right direction  and you have a couple options to accomplish this  but let s start by finding the correct SDK folder first     Finding your SDK    From Package Manager    If you are using a package-based JRE install like Java 8 JRE via a the custom PPA in a Debian-based distribution  or used OpenJDK  the directory will most likely be  usr lib jvm java-8-oracle  or whatever version you have chosen   You can find this path set in the JAVA HOME environment variable     echo  JAVA HOME   usr lib jvm java-8-oracle     Manual Download    If you have installed via the Java JRE SDK download  it will be wherever you placed the folder  e g   home username jdk-8u121 1 8 0  or something similar    Scripted installs may even add the SDK to  opt java-8-oracle  but as of this writing  the Java Install instructions leave the folder placement in your hands      Android Studio 2 2    Lastly if you are using Android Studio  the SDK is placed where you have set it to place the SDK files downloaded through the Studio s SDK Manager  By going to File   Settings   Appearance  amp  Behavior   System Settings   Android SDK  you can find the SDK location setting at the top with the option to change  and the default folder being   Android Sdk     Setting the SDK Path  Now that we know where the SDK is  it is time to let react-native know     Option 1  Set with local properties    This method is very simple  and all that is needed is creating the file local properties in the following folder  where Project Folder is the base of your React-Native application    Project Folder Android App  In your local properties  you want to set the variable sdk dir to the path of your SDK folder   sdk dir  home username Android Sdk   While this is the easiest way to remedy the issue  it is not the best  especially if you work with multiple projects  For every project  you will have to create this file for every project  and if the folder changes plan on changing this file for each project s local properties   Once the file is saved  rerun the react-native run-android command     Option 2  Settings Folders with Environment Variables    The other option is to set the SDK folders to the local environment variables that React-Native looks for by default  To do so  we will add the ANDROID HOME path  As a bonus we can also add our android tools in the same place  We need to add this to rather the  bash profile or  profile files in our home directory  which are loaded last  so we can make sure that nothing else is overriding the settings we make  Since these are in your home directory  there is no need to edit with escalated privileges       vim    profile     use nano or pico if you prefer    In the file add the following lines replacing the SDK folder with the one you found above  I will be using the Android Studio folder as an example   export ANDROID HOME    Android Sdk  export PATH  PATH   Android Sdk tools   Android Sdk platform-tools   Save the file  then apply the profile settings     source    profile   echo  ANDROID HOME  home dbrown Android Sdk   If the Sdk folder shows correctly  congratulations  Re-run your react-native command  and watch the app build process continue forward     If you still have issues    If for some reason you receive the error    failed to find target with hash string  android-23  in  your sdk folder  you need to make sure that the project s build version and the version of the SDK installed match  React-Native defaults to 23 0 1   You can find the default version in Project Folder android app build gradle  and then searching for buildToolsVersion  You can of course change the version from this file  or in Android Studio go to File   Project Structure to change the Project SDK  I would not suggest changing this version unless you absolutely know what you are doing  otherwise install the SDK version the project is looking for

For Linux Users  Your app is not getting the path of android-sdk  so If you are using linux  ubuntu   than you need to add a file named  local properties  and save it inside the android folder  which is created inside your app folder   You need to add below line inside local properties file  which is the path of your android-sdk lies inside your system inside system in order to run the app   sdk dir  opt android-sdk   save and rerun the command react-native run-android  OR  you can open terminal  type  sudo nano    bashrc  and paste the below path at the end of the file  export ANDROID HOME   opt android-sdk    and restart your computer and run again react-native run-android after that   Note - If you put set path in  bashrc file  then you don t even need to create local properties file
