Could not find com.android.support:appcompat-v7:25.3.1

Question

I suddenly started getting this error when trying to build. This was all working a few weeks ago with no changes that I know of. The issue seems to be related to react

Answer 1

For this, try one of the following option:

1. Update your SDK manager > Go to build menu > clean project > then build project

or

2. Right click on project folder > open module setting > libraries > add com.android.support:appcompat-v7:25.3.1 > sync the project

3. Click on file menu > open project structure > and file the libraries
