Instant Run takes longer than standard builds

Question

It’s been some time now that Instant Run is not working anymore, that is, it’s slower than standard builds.

There’s some material in the AOSP bug tracker, but I could not work this out. I’m sure some of you will help.

Without Instant Run

Builds take about 1.30 min.

With Instant Run

I run the app for the first time, then apply some minor change. For example, change int a = 1 to int a = 2 inside a method, or alter a string.

Then click run again. What happens:

• A seemingly full build takes place (calling assembleDebug on all my modules). Takes about 1.30 min.

• A second round goes on, calling just app:assembleDebug. It takes about another minute:

  16:27:10 Executing tasks: [:app:assembleDebug]
  16:28:16 Gradle build finished in 1m 5s 264ms
  16:28:22 Instant Run applied code changes and restarted the app.
  

During the first round, no output whatsoever to Event Log or Gradle Console. During second round, the Gradle Console outputs lots of stuff and ends with

BUILD SUCCESSFUL

Total time: 51.385 secs
PREDEX CACHE HITS:   0
PREDEX CACHE MISSES: 45
Stopped 0 compiler daemon(s).

What can I do?

I have these in my grade.properties file:

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

Nothing dex related in build.gradle files. Not using Jack. Android Studio 2.2.3.

Update to the latest version of Android Studio and then increase the memory profile in (studio.vmoptions) based on your system memory

    -Xms256m
    -Xmx1280m
-XX:MaxPermSize=350m

Answer 2

Enable Instant Run

1. Open the Settings or Preferences dialog.
2. Navigate to Build, Execution, Deployment > Instant Run.
3. check the box next to Enable Instant Run.

Limitations of Instant Run.

Deploying to multiple devices, Multidexing your app, Using third-party plugins, Pushing changes to multi-process apps, Launching your app in a Work profile.

If you use multidex support (multiDexEnabled true) for your app, minSdkVersion must be 21 or higher. Otherwise, android studio disables Instant Run.

Android plugin for gradle version must be 2.1.0 or higher

Enable Offline Work android studio to speed up:

Go to file >> settings or simply press ctrl + alt + s

file >> settings >> Gradle. please check Offline work under Global Gradle setting

Improve Gradle Performance

After opening android studio, open gradle.properties file from right side of android studio and add the following two lines.

  org.gradle.jvmargs=-Xmx1536m  
  org.gradle.daemon=true
  org.gradle.parallel=true

Configure Build Variants of debug in buildTypes

debug {
        minifyEnabled false
        applicationIdSuffix ".debug"
    }

After changes, you should restart your Android Studio.

Note: Build time depend on your processor and RAM. I noticed in (i7-3610qm with 8gb ram) when you compile 4 android studio project at same time then slow respond on window. after build process finish pc works normal.
