Error:Unknown host 'jcenter.bintray.com'.

Question

Error:Unknown host \'This is usually a temporary error during hostname resolution and means that the local server did not receive a response from an authoritative server\'.

Answer 1

Sometimes this works for me, when there's a sudden gradle syncing problem which should work fine (or previously worked fine).

Build with local gradle distribution

Download a gradle release archive from here to path android-studio/gradle/ folder, and extract it.

In Android Studio: File > Settings > Build, Execution > Gradle.

Select 'Use local gradle distribution' under 'Project-level settings'.

In 'Grade home', browse to the path of the downloaded gradle and select it.

OK > Sync project.

P.S. if local gradle is already selected, try reverse i.e. default wrapper.

Answer 2

Just clean and Rebuild the project. This worked for me
