error occurred configuring project react-native-photo-view

Question

I have just started with ReactNative and created a project using this tutorial. The project got built and a android application got installed on my phone.

Then I used @shoutem/ui library for UI components. According to the documentation, I tried

npm install @shoutem/ui --save
react-native link

and then run the project using

react-native run-android

But then I got this error

PS D:\SK\Study\ReactNative\DemoRN> react-native run-android
Scanning folders for symlinks in D:\SK\Study\ReactNative\DemoRN\node_modules (38ms)

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
https://facebook.github.io/react-native/docs/android-setup.html

And then I unlinked the @shoutem/ui

react-native unlink @shoutem/ui

and tried to run the project, but still, I am facing the same issue?

Please ignore if it is too basic to ask, But I am not able to understand what is the issue?

Update

I am not using Android Studio, So I downloaded the build-tools 25.0.0 and placed in sdk/build-tools folder. But now I am facing

> A problem occurred configuring project ':react-native-photo-view'. > Failed to find Platform SDK with path: platforms;android-23

Answer 1

This seems to be an issue with the available SDK Tools in your installation of Android Studio:

      > Failed to find Build Tools revision 25.0.0

Installing these should resolve the issue. To install this, start up Android studio, go to the SDK Manager and select the SDK Tools tab, check the Show Package Details option in the bottom right corner and then check the 25.0.0 SDK Tools and click Apply to download and install them.

Here's a screenshot of the SDK Tools I use for my local environment for reference:

Furthermore, I'd just like to elaborate on the react-native (un)link command. This is used to link native dependencies into your React Native project. Unlinking it is not the same as uninstalling it, you should still be able to use all non-native components of the Shoutem UI Toolkit after unlinking the package.

Answer 2

I am not using Android Studio, So I downloaded the build-tools 25.0.0 and placed in SDK/build-tools folder. This solved the build tools issue but then there was a new issue

A problem occurred configuring project ':react-native-photo-view'. > Failed to find Platform SDK with path: platforms;android-23 

The network I was using has configured some firewalls rules that were not allowing the required dependencies get downloaded. When you run react-native run-android it downloads all the dependencies automatically to create the build.

So In my case, I changed my network settings and this worked.
