Stuck with Gradle Build Running

Actually it is not stuck. It takes more time to build. I have got almost 3 solutions that can fix the issue.

Solution-1:

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:

org.gradle.daemon=true

org.gradle.parallel=true

Solution-2:

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 -> Build Tools -> Gradle

Check the 'Offline work' under 'Global Gradle settings'

It will reduce 90% gradle build time.

Solution-3

If you are using Google Play services, make sure you aren't using this in your Gradle build script:

compile 'com.google.android.gms:play-services:8.3.0'

Only use those Google APIs that your app is really using. If all you are using is Google Maps, you would use this:

com.google.android.gms:play-services-maps:8.3.0

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:

Solution#4:

Arun George has commented the following solution.

the issue was due to certain 32 bit libraries missing. Had to do sudo apt-get install lib32z1. Adding to gradle.properties helped reduce the build time.

For my case I had to install gcc-multilib

$ sudo apt-get install gcc-multilib

Check the Gradle Console at the bottom right as it has more output than the Event log.

Changing buildToolsVersion was the solution for me.

The issue is that the project isn't synced with the gradle files. The resolution I did was go to File > Sync Project with Gradle Files and it was able to sync.
