In gradle file by changing maxheap size we can increase dex memory but after gradle plugin 2.1 dex is in process. Let’s see how to do it.ĩ.In gradle.properties file change the memory assigned for JVM according to app requirements.Change = -Xmx1536m(Default). Compared to the previous compiler, called DX, D8 compiles faster and outputs smaller DEX files, all while having the same or better app runtime performance.This newer plugin version will lead to up to 25% reduce timing of build.Ģ.If you are using command line to build ,Avoid Legacy Multidex- If our app exceeds 64k Method Reference Limits we have to use Multidex.When in gradle file we have minSdkVersion 2.3 version and using run button to make build it will automatically use native multidex if connected device version is >21 and legacy if version is <21.If you are using command line to make build then inside development flavour set minSdkVersion 21.This will lead to up to 10% reduce timing of build.ģ.Disable Multiple apk for developments- We can create multiple apk for specific device configurations using splits block, it reduce app size in release build but it is not required in development.By disabling it we can further reduce build time by 10%. dex bytecode for the Android Runtime (or Dalvik, for older versions of Android). DEX compilation is the process of transforming. By default, Android Studio now uses D8(You can also disable it ). By default, Android Studio now uses a new DEX compiler called D8. In the new Android studio it has been lot faster than the previous version but still there is lot of scope to fasten it so Let’s Make it Fast by Doing some quick fixes in Android Studio.In Google I/O 2017 Google team focus on this ,this article is extracted from there.ġ.Always use latest android Gradle Plugin -Android studio incrementally improves performance in newer gradle version so it is recommended to use latest one.Currently latest gradle plugin is 3.1.2 In this version studio has changed it’s compiler DEX to D8. If you are an android developer, you are spending lot of time looking at your screen and waiting for gradle build to finish.
