React Native Run Android not accepted license agreement of the following sdk components Android sdk build tools 26

Question

Currently I am working on developing a React Native app where I installed two components:

1) React Native Elements UI Toolkit 2) mastermoo/react-native-action-button for FAB button

Before installing the above components, the app was compiling and running fine on my device but post installation of the above components I was getting couple of errors where I didn't have Android API level up to 26 (Android 8.0) installed and installed all of it overnight.

Post installation of the required APIs, I am getting the following error now which I am unable to solve:

A problem occurred configuring project ':app'.

Could not resolve all dependencies for configuration ':app:_debugApk'. A problem occurred configuring project ':react-native-vector-icons'. You have not accepted the license agreements of the following SDK components: [Android SDK Build-Tools 26.0.1].

Tech Specifications:

1) Operating System: Windows 10 (Really fed-up of Windows, soon buying MacBook Pro)

2) Installed Android APIs - 4.2.2 - 8.0 (API 26)

Would be great if you all could help me solve this issue.

Thank you and best regards. -Rohit

Answer 1

Finally after a lot of head banging and hair pulling since last 2 days, I've solved this painful issue which one may face while working on Windows environment. The require steps are:

A) Set proper Environment Variables

1) Under User Variables make sure you have ANDROID_HOME and adb variable Path are set like:

ANDROID_HOME C:\Android\sdk

adb C:\Android\sdk\platform-tools

2) Under System Variables, make sure you have set these Path variables(my sdk is installed at C:\Android, use yours path as per what and where you have on your system):

C:\Android\sdk\platform-tools

C:\Android\sdk\tools

C:\Android\sdk\tools\bin

B) Close all open Folders/File Explorers and exit all Command Prompt Terminals

C) Open a command prompt terminal as Administrator and issue the below commands (make sure adb and sdkmanager command are accessible from anywhere without changing directory to the SDK directories):

sdkmanager "build-tools;26.0.1"

I was having build tool license issue so the above command. Nevertheless, Accept the license by typing Y, wait for it to print "done"

cd android && gradlew clean

THEN

cd .. && react-native run-android
