you can set file->setting->search 'Gradle'-> check 'use local gradle distribution' and check 'offline work'.. in android studio. it will improve gradel building time.

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

1- Make sure you’re using the latest version of Gradle. Generally with every new update there is a significant improvement in performance. Note: Java 1.8 is faster than 1.6. Make sure it’s updated too.

2- Try to minimize the use of modules. There are many cases where we need to fork the library to modify it to fit according to our needs. A module takes 4x greater time than a jar or aar dependency. This happens due to the fact that the module needs to be built from the scratch every time.

3- Enable gradle Offline Work from Preferences-> Build, Execution, Deployment-> Build Tools-> Gradle. This will not allow the gradle to access the network during build and force it to resolve the dependencies from the cache itself.

Note: This only works if all the dependencies are downloaded and stored in the cache once. If you need to modify or add a new dependency you’ll have to disable this option else the build would fail.

4-Open up the gradle.properties file from the root of your project. Add the following lines of code in it.

org.gradle.daemon=true

Gradle daemon is a background process. Adding this would consume some extra memory while building.

org.gradle.parallel=true

The above line of code enables compilation of multiple modules at the same time. Besides that it also gives us other benefits such as;

Re-using the configuration for unchanged projects Project-level is up-to-date checks Using pre-built artifacts in the place of building dependent projects Adding the following line of code also aids us in speeding up the build.

org.gradle.configureondemand=true

Another important property is;

org.gradle.jvmargs=-Xmx2048m -XX:MaxPermSize=512m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

The above line is used to allow Java compilers to have available memory up to 2 GB (2048 MB). It should only be used if you have available memory more than 2 GB.

This is how the gradle.properties file should look like:

enter image description here

5- Avoid dynamic dependencies such as compile 'com.google.maps.android:android-maps-utils:0.4+'. Dynamic Dependencies slow down your build since they keep searching for the latest builds every time. To improve the performance we need to fix the version in place.

6- Use only those dependencies that you need. For example google maps dependency, instead of importing , like :

 implementation 'com.google.android.gms:play-services:17.0.0' 
 implementation 'com.google.android.gms:play-services-maps:17.0.0'

Gradle build speed depends on a lot of factors including the specification of your machine as well as your build type and android studio settings. You can check out this article on how to reduce your build time or go through the steps in the Android developer website.


Personal experience:

When I faced this issue, enabling offline mode drastically reduced my build time. The only problem is that I have to toggle this setting (on and off) every time I want to add a new dependency and this almost made me go berserk on several occasions. However, if properly handled, this helps a great deal.

I hope this helps. Merry coding!
