- No cached version of gradle 5 answers
I am new to android studio IDE development. Every time when I imported a sample project that developed in the android studio, I am getting this error..
No cached version of com.android.tools.build:gradle:1.1.0 available for offline mode. Disable Gradle 'offline mode' and sync project.
How can I solve this problem.
Go to File -> Settings.
And open the 'Build,Execution,Deployment'
. Then open the
Build Tools -> Gradle
Then uncheck -> Offline work on the right.
Click the OK button.
Then Rebuild the Project.
For Mac OS:-
go to Android Studio -> Preferences, and the rest is the same. OR follow steps given in image
[

Gradle is in offline mode, which means that it won't go to the network to resolve dependencies.
Go to Preferences > Gradle and uncheck "Offline work".
In Android Studio open the settings and search for offline it will find the Gradle
category which contains Offline work. You can disable it there.

@mikepenz has the right one.
You could just hit SHIFT+COMMAND+A (if you're using OSX and 1.4 android studio) and enter OFFLINE
in the search box.
Then you'll see what mike have shown you.
Just deselect offline
.
Offline mode could be set in Android Studio and in your project. To verify that gradle won't build your project in offline mode:
- Disable gradle offline mode in Android Studio gradle settings.
- Verify that your project's gradle.settings won't contain: startParameter.offline=true
