android - Gradle Build Failing on Azure Pipelines Due to RAM Limitations - Stack Overflow

I'm facing an issue with Gradle builds failing on our Azure Pipelines CI/CD setup due to insufficient memory. The VM we use has 16GB of RAM, but at certain points during the build, it runs out of resources and crashes.

Is it normal for an Android build to require more than 16GB of RAM? Are there any optimizations I can make on my end as an Android developer to reduce memory usage?

In case it helps, in my application, I make use of dagger hilt and it is single module. Any insights or suggestions would be greatly appreciated!

Android builds can be memory hogs, especially with Dagger Hilt, Kotlin, and large projects. But 16GB should usually be enough if managed properly.

You can set these settings which can help you prevent OOM (basically limit gradle usage)

.gradle.jvmargs=-Xmx4g -XX:MaxMetaspaceSize=512m -XX:+HeapDumpOnOutOfMemoryError
.gradle.parallel=true
.gradle.daemon=true
.gradle.configureondemand=true
.gradle.caching=true

Usually Azure VMS also have limited cores, you can also limit the thread spawns

.gradle.workers.max=2

Also I would recommend you to move to a multi module approach, which only builds whats needed, inspite of whole app module.
