While trying to build my Application on Android Studio 2.1 (On Ubuntu 16.04), it gets stuck on the below note:
Executing tasks: [:app:generateDebugSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:generateDebugAndroidTestSources]
Actually it is not stuck. It takes more time to build. I have got almost 3 solutions that can fix the issue.
Following the steps will make it 10 times faster and reduce build time 90%
First create a file named
gradle.properties in the following directory:
/home/<username>/.gradle/ (Linux) /Users/<username>/.gradle/ (Mac) C:\Users\<username>\.gradle (Windows)
Add this line to the file:
If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build, probably its trying to reach the proxy server and waiting for a timeout. When I removed the proxy server setting its working fine.
In Android Studio go to
File -> Settings -> Build, Execution, Deployment -> Buil Tools -> Gradle
'Offline work' under
'Global Gradle settings'
It will reduce 90% gradle build time.
If you are using Google Play services, make sure you aren't using this in your Gradle build script:
Only use those Google APIs that your app is really using. If all you are using is Google Maps, you would use this:
When I did this, my compile time went from over 2 minutes to around 25 seconds. For a list of the Google apis that you can selectively compile against, see:
