Android Studio gradle takes too long to build

Question

My Android Studio project used to build faster but now it takes a long time to build. Any ideas what could be causing the delays? I have tried https://stackoverflow.com/a/27171878/391401 but no effect. I haven't any Anti virus running which could interrupt the builds. My app is not that big in size as well (around 5MB) and it used to build within few seconds but not sure what has changed.

10:03:51 Gradle build finished in 4 min 0 sec  
10:04:03 Session 'app': running  
10:10:11 Gradle build finished in 3 min 29 sec  
10:10:12 Session 'app': running  
10:20:24 Gradle build finished in 3 min 42 sec  
10:28:18 Gradle build finished in 3 min 40 sec  
10:28:19 Session 'app': running  
10:31:14 Gradle build finished in 2 min 56 sec   
10:31:14 Session 'app': running  
10:38:37 Gradle build finished in 3 min 30 sec  
10:42:17 Gradle build finished in 3 min 40 sec  
10:45:18 Gradle build finished in 3 min 1 sec  
10:48:49 Gradle build finished in 3 min 30 sec  
10:53:05 Gradle build finished in 3 min 22 sec  
10:57:10 Gradle build finished in 3 min 19 sec  
10:57:11 Session 'app': running  

Solution 1

Found the reason!! 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.

Removing proxy: File > Settings > Appearance & Behavior > System settings > HTTP Proxy

Solution 2

Update 2022; Google removed "Offline work" option;

They added "Donwload external annotations for dependencies" option, but of course unchecking that option does not provide the same speed improvements.

Answer

In Android Studio go to File -> Settings -> Build, Execution, Deployment -> Build Tools -> Gradle

(if on mac) Android Studio -> preferences... -> Build, Execution, Deployment -> Build Tools -> Gradle

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

Note: In newer version of Android studio, View->Tool Windows->Gradle->Toggle button of online/offline

It will reduce 90% gradle build time.

if you just added a new dependency in your gradle you will have to uncheck the offline work or gradle will not be able to resolve the dependencies. After the complete resolving then you you can check the offline work for a faster build

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:

https://developers.google.com/android/guides/setup

Solution 4

Found an easy and best way to build gradle

go to your app >> open your gradle.properties and change few lines from it [remove #]

else you may copy paste my below snippet as well

    # Project-wide Gradle settings.

# IDE (e.g. Android Studio) users:
# Gradle settings configured through the IDE *will override*
# any settings specified in this file.

# For more details on how to configure your build environment visit
# http://www.gradle.org/docs/current/userguide/build_environment.html

# Specifies the JVM arguments used for the daemon process.
# The setting is particularly useful for tweaking memory settings.
# Default value: -Xmx2048m -XX:MaxPermSize=512m
 org.gradle.jvmargs=-Xmx4096m -XX:MaxPermSize=1024m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

# When configured, Gradle will run in incubating parallel mode.
# This option should only be used with decoupled projects. More details, visit
# http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects
 org.gradle.parallel=true

it worked for me earlier it take almost 2-3 minutes now it is taking only 5-6 second

in above scenario my mac machine have 8GB ram so i assigned 4gb for gradle

Solution 5

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

What do you use, your android phone or any emulator to run your application?

[AndroidDev]

Running on the device

[JAvAd]

Please Read this post: stackoverflow.com/questions/22550761/…

[Neo]

really to slow... It takes 6 mins to build after cleaning app and at first time.

[Andrew S]

When Android studio was new, many on StackOverflow dismissed complaints about this because it was 'only a beta version'. However, its now been some years since it was 'only a beta' and it's still sluggish and that's on 8 cores, 16gb of ram and an SSD disk. The old Eclipse set up on this machine is as fast as a blink.

Some of this is also dependent on dependencies that may need to be built.

How to remove the proxy server ?

[AndroidDev]

On Windows File > Settings > Appearance & Behavior > System settings > HTTP Proxy

[user3098756]

My problem was also in proxy, but in that , that I had to add also HTTPS proxy in gradle properties. HTTP proxy was not enough: systemProp.http.proxyHost=xxx.xxx.xxx.xxx systemProp.http.proxyPort=8080 systemProp.https.proxyHost=xxx.xxx.xxx.xxx systemProp.https.proxyPort=8080

[Sauron]

You deserve 100+ upvotes. Every other source suggests adding org.gradle.parallel=true and command line related...but none provide a simple and straightforward understanding of what is really going on. Using your advice, my build time went from 1 min 5 secs, to 3.427 seconds. Awesome!!

[Ramesh]

Worked great. From 12 mins to 5 seconds

[Dany Y]

won't this configuration stop fetching new libraries when we add them to build.gradle ?

[Biswajit Karmakar]

when you add a new library then you have to make it online just for one time which will be notified by gradle build to make project runnable @DanyY

[Biswajit Karmakar]

You can set it directly from gradle.properties located under studio project.

[user779370]

Yes also enable this option org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

[Biswajit Karmakar]

Set MaxPermSize=1024m

[The_Martian]

AS is complete joke and bs. I am just tired of this nonsense.

[alnaji]

Thanks a lot,this was my main problem too. Now everything working great.

[PC.]

Works great. Use this link to find your play services library name: developers.google.com/android/guides/…

[Karue Benson Karue]

You deserved a tick... You have solved my problem. The problem is on google play services... Thanks :)

[Josh]

I agree!!! I am suffering unholy amounts of pain to migrate a big project from Eclipse, and now that errors are cleared, building with AS never finishes!!! I hate AS @The_Martian

[Admin]

Does it mean that all the time the issue was internet speed instead of processor speed?

[magritte]

Not only did this help with the long build issues but I can now also deploy directly to the Android device without using Proguard when debugging (previously I was getting an error about 65K method limit). thanks!

[magritte]

@Josh I have the same issue... it's been building for 56 minutes now and hasn't finished... did you find a solution? I might switch back to using Eclipse grrr it's taken me ages to migrate the project to AS... I stupidly assumed it would be better / the new shiny.

[Josh]

I just did the typical reset/reopen/build/clean/tweak gradle like mad, and switched to offline and after like 2 hours the build time dropped to normal times. I really don't know what happened. @magritte

[oli]

Why are those properties not predefined?? Are there any downsides?

[javad]

This option should only be used with decoupled projects. More details, visit gradle.org/docs/current/userguide/…

[Neon Warge]

errr would it really hurt to just put an error message stating that?

[Karol Żygłowicz]

Yes I agree. To enable java 8 in android studio you need to use Jack and by doing this my build times fly to the moon from 1-2 minute builds to 16 minutes... what the .... It is unusable right now. As always great work Google

[Amod Gokhale]

@AndroidDev - this helps in 2018!!!. Do you know if this is a bug or this is how gradle build should work?

[Jonathan.]

Why does it need to connect to a server to build something?

[Mohd.Zafranudin]

Be sure to allow Android Studio on Firewall. Was waiting for almost 15 minutes for the gradle on a fresh install when suddenly Firewall window popup asking me to allow it. Could've been sooner though

[meyasir]

Amazed!! minimize time from 1 min to 2 secs on SSD.

[Programming Pirate]

This reduced my build time from 30+ minutes to 24 mins... Is there any way to reduce further...?

[Cardinal System]

Woah! Went from over 15 minutes to 1 minute :O

[drlolly]

unfortunately this did not have any effect on my system.

[David Innocent]

As guys are getting answers...am 11 minutes in waiting for game to finish

[Fugogugo]

is it only me or there's no Offline Work option anymore in Android Studio 3.6.2?

[gumuruh]

greaaaat....!! after 1st compilation now when i switch to offline, everything was blasttt....! great :D

[Peter]

@Fugogugo - take a look at these posts: stackoverflow.com/questions/57797772/….. and stackoverflow.com/questions/60475046/…

[Prajwal Waingankar]

As of Android 4.1: Removing proxy: File > Settings > Appearance & Behavior > System settings > HTTP Proxy > No proxy

[Chagai Friedlander]

@ProgrammingPirate did you find a way? I'm having the same problem and this did not help - I have 32 GB RAM and my computer(Windows) is great just Android Studio is slow

[Ayxan Haqverdili]

[Victor Sokoliuk]

Thanks a lot man, I really couldn't to figure out with it by myself.

[Reza]

tnx good stack overflow fellow. your simple solution saved a lot of time for me.

[Asad Mahmood]

yes it often happens but once gradle sync process is completed toggle to offline mode if internet speed is very slow unless you have add a new dependency

[MML]

Can you please clear which gradle file I am using classpath 'com.google.gms:google-services:4.3.10' this in module app

[Maulik Dodia]

@PrajwalWaingankar I have No proxy selected but still I'm facing this issue. Is there any other solution?

[Prajwal Waingankar]

Use SSD, atleast 8gb ram, if not an high-end pc: run multitasking.
