Whenever I hit "Instant Run" icon without any modification to source code, I get 2-3 min avg build time with a message
Instant Run applied code changes and restarted the app. Field Type Change.
I printed how long every task took using this and pasted my logs here. I have highlighted the tasks that took longer than 1 second.
Can anyone please quickly go through the logs and tell me what is going on? What can I do to avoid these long instant run times? It is becoming practically impossible now to do development.
Executing tasks: [:baymax:assembleDevelopmentDebug]
Configuration on demand is an incubating feature.
The ConfigurableReport.setDestination(Object) method has been deprecated and is scheduled to be removed in Gradle 4.0. Please use the method ConfigurableReport.setDestination(File) instead.

BUILD SUCCESSFUL in 3m 28s
147 actionable tasks: 96 executed, 51 avoided (35%)
答案 0 :(得分：3)
此视频确实帮助https://www.youtube.com/watch?v=7ll-rkLCtyk减少了我的构建时间。有一个与此视频相关的优秀博文：https://android.jlelse.eu/how-to-speed-up-your-slow-gradle-builds-5d9a9545f91a
我做了以下事情以提高速度：
在开发中禁用abi拆分（如果要根据CPU架构创建不同的apks，则只需执行此操作）：
splits {
abi {
enable !project.hasProperty('devBuild')
}
}
在开发中禁用png cruncher：
android {
if (project.hasProperty('devBuild')) {
aaptOptions.cruncherEnabled = false
}
}
每次点击运行时都不要修改BuildConfig：
def gitSha = project.hasProperty('devBuild') ? "gitSha_devBuild" : 'git rev-parse --short HEAD'.execute([], project.rootDir).text.trim()
def buildTime = project.hasProperty('devBuild') ? "buildTime_devBuild" : new Date().format("yyyy-MM-dd'T'HH:mm'Z'", TimeZone.getTimeZone("UTC"))
然后再说：
buildConfigField "String", "GIT_SHA", "\"${gitSha}\""
buildConfigField "String", "BUILD_TIME", "\"${buildTime}\""
在开发期间针对minSdkVersion 21进行构建和仅针对您在开发设备中所需的资源（在我的情况下，它是＆＃34; en＆＃34;和＆ ＃34; xxhdpi＆＃34）：
productFlavors {
fast {
// Enable pre-dexing to produce an APK that can be tested on
// Android 5.0+ without the time-consuming DEX build processes.
minSdkVersion 21
//only package english translations, and xxhdpi resources
resConfigs("en", "xxhdpi")
}
slow {
// The actual minSdkVersion for the production version.
minSdkVersion 16
}
}
转到com.android.tools.build.gradle:3.X.X
现在我的构建速度从10秒到1分钟不等！
