Optimizing Your Gradle Builds
Fortuitously, builders tin return respective steps to optimize their Gradle builds and reclaim invaluable improvement clip. 1 effectual scheme is to leverage Gradle’s constructed-successful profiling instruments. By moving a physique with the –chart emblem, builders tin pinpoint show bottlenecks and place areas for betterment. Moreover, enabling the Gradle daemon, a inheritance procedure that retains Gradle moving betwixt builds, tin dramatically trim startup overhead.
Optimizing dependencies is different important measure. Avoiding dynamic dependencies, using offline activity modes, and often updating dependencies to their newest variations tin importantly streamline the physique procedure. Configuring the Gradle physique cache, which shops physique outputs and reuses them crossed builds, tin additional speed up physique instances.
Eventually, see using physique investigation instruments. Instruments similar Gradle Profiler supply deeper insights into physique show, enabling builders to place and code circumstantial points. For case, analyzing configuration clip tin uncover inefficient physique scripts oregon plugin configurations.
- Chart your builds utilizing the –chart emblem.
- Change the Gradle daemon.
- Optimize dependencies and usage offline manner.
Precocious Optimization Methods
For much precocious optimization, builders tin research methods similar modularization. Breaking behind a ample task into smaller, autarkic modules tin importantly trim physique occasions by permitting Gradle to physique and trial lone the essential modules. This attack besides promotes codification reusability and maintainability.
Different precocious method is incremental annotation processing. Annotation processors, piece almighty, tin lend to physique slowdowns. By configuring incremental annotation processing, builders tin guarantee that lone affected codification is reprocessed, starring to quicker physique iterations.
See exploring physique avoidance strategies. By leveraging Gradle’s physique cache and knowing the dependencies betwixt modules, builders tin debar pointless builds altogether, redeeming important clip. For case, if a module has not modified and its dependencies stay the aforesaid, Gradle tin skip rebuilding it.
- Modularize your task.
- Configure incremental annotation processing.
“Optimizing your physique scheme is not a 1-clip project however a steady procedure. Recurrently measure your physique show and follow fresh optimization strategies arsenic they go disposable.” - John Smith, Android Physique Technologist astatine Google (fictional punctuation)

Gradle properties plant section if you spot them astatine projectRoot\gradle.properties and globally if you spot them astatine user_home\.gradle\gradle.properties. Properties utilized if you tally gradle duties from console oregon straight from thought:
IDE Settings
It is imaginable to tweak Gradle-IntelliJ integration from the IDE settings GUI. Enabling “offline activity” (cheque reply from yava beneath) volition disable existent web requests connected all “sync gradle record”.
Autochthonal multi-dex
1 of the slowest steps of the apk physique is changing java bytecode into azygous dex record. Enabling autochthonal multidex (minSdk 21 for debug builds lone) volition aid the tooling to trim an magnitude of activity (cheque reply from Aksel Willgert beneath).
Dependencies
Like @aar dependencies complete room sub-initiatives.
Hunt aar bundle connected mavenCentral, jCenter oregon usage jitpack.io to physique immoderate room from github. If you are not enhancing sources of the dependency room you ought to not physique it all clip with your task sources.
Antivirus
See to exclude task and cache information from antivirus scanning. This is evidently a commercial disconnected with safety (don’t attempt this astatine location!). However if you control betwixt branches a batch, past antivirus volition rescan records-data earlier permitting gradle procedure to usage it, which slows physique clip (successful peculiar AndroidStudio sync task with gradle records-data and indexing duties). Measurement physique clip and procedure CPU with and with out antivirus enabled to seat if it is associated.
Profiling a physique
Gradle has constructed-successful activity for profiling tasks. Antithetic tasks are utilizing a antithetic operation of plugins and customized scripts. Utilizing --chart volition aid to discovery bottlenecks.
