SDK Build Tools	23.0.2	23.0.2	Install or configure SDK Build Tools.

New:

• Added support for the N Developer Preview, JDK 8, and Java 8 language features using the Jack toolchain. To find out more, read the N Preview guide.

  Note: Instant Run does not currently work with Jack and will be disabled while using the new toolchain. You only need to use Jack if you are developing for the N Preview and want to use the supported Java 8 language features.

• Added default support for incremental Java compilation to reduce compilation time during development. It does this by only recompiling portions of the source that have changed or need to be recompiled. To disable this feature, add the following code to your module-level build.gradle file:

  Groovy

  android {
    ...
    compileOptions {
      incremental false
    }
  }
  

  Kotlin

  android {
    ...
    compileOptions {
      incremental = false
    }
  }
  

• Added support for dexing-in-process which performs dexing within the build process rather than in a separate, external VM processes. This not only makes incremental builds faster, but also speeds up full builds. The feature is enabled by default for projects that have set the Gradle daemon's maximum heap size to at least 2048 MB. You can do this by including the following in your project's gradle.properties file:

  ```none org.gradle.jvmargs = -Xmx2048m ```

  If you have defined a value for javaMaxHeapSize in your module-level build.gradle file, you need to set org.gradle.jvmargs to the value of javaMaxHeapSize + 1024 MB. For example, if you have set javaMaxHeapSize to "2048m", you need to add the following to your project's gradle.properties file:

  ```none org.gradle.jvmargs = -Xmx3072m ```

  To disable dexing-in-process, add the following code to your module-level build.gradle file:

  Groovy

  android {
    ...
    dexOptions {
        dexInProcess false
    }
  }
  

  Kotlin

  android {
    ...
    dexOptions {
        dexInProcess = false
    }
  }
