Answer 1

I had a same problem and I fix it with the following steps:

1. check the event log and if you see the errors like "cash version is not available for the offline mode" follow the steps.
2. click on View => Gradle then new window will open.
3. click on the WIFI icon and then sync the Gradle. "if you see different errors from what I mentioned in number one, please go to the file -> project structure -> and there is suggestion"

Answer 2

you should have gradle.properties file defined for the build with proxy settings so that gradle knows how to use http connection

# This file contains the basics for Maven Version control and will be used by the Artifactory Release management
# These settings are for the root project and all sub-projects in this application

releaseGroup=com.xx.xx.xx
artifactory_user=

systemProp.http.proxyPort=8080
systemProp.https.proxyHost=proxy.xxx.com

Answer 3

I got the same problem. Just use File->INVALIDATE CACHES AND RESTART

Answer 4

I was facing the same issue, it was because of the cache. You just need to follow these Steps:

1. Go to File -> Invalidate Caches / Restart
2. After restarting Android Studio, connect your PC to a good network.
3. Go to build and choose rebuild, and Android Studio will automatically download the missing files for the project

Answer 5

The solution is in your build.gradle change this block:

allprojects {
  repositories {
    jcenter()
    google()
  }
}

to google in first position :

allprojects {
  repositories {
    google()
    jcenter()
  }
}

Answer 6

If adding google() into your build.gradle doesn't work try adding it at first place in your repositories section of node_modules/YOUR_PACKAGE/android/build.gradle file.
