android.dexOptions.incremental property is deprecated

Question

When trying to run gradle build, I get following warning in Android Studio 2.2 :

Warning:The android.dexOptions.incremental property is deprecated and it has no effect on the build process.

In build.gradle file here I have declare dexOptions

dexOptions {
   incremental true
   jumboMode = true
}

If it is deprecated then what is the alternate option of this attribute.

Answer 1

By default incremental is turned on Java compilation in 2.1.0-rc1 (2016/4/22) or later. So its redundant to declare it in build.gradle file.

Answer 2

Changes in Gradle 2.1.0-rc1 (2016/4/22) or later.

1. Remove deprecated dexOptions.incremental. Incremental Java compilation is ON by default.

2. No need to write jumboMode too, Jumbo mode is ON by default in instant-run mode.

First stable v2.1.0 (2016/4/26)

Visit official gradle site for more details

Instant Run changes

Android Studio 2.3 Canary 3 and newer has change to how Instant Run works.

Applying changes to a running applications is no longer tied to the Run button. The Run button will now always perform an application restart. To apply code and resource changes in the running process, there is a new button right next to it, "Apply Changes", which attempts to hotswap the changes into the app. -> ref

So that jumboMode may not effect from run button. thanks

Answer 3

Solve Problem after removing deprecated

dexOptions { incremental true }

Incremental Java compilation is ON by default.
