MultiDex Build in Android

Refer to Multidex Build property for more information.

Gradle Options

Specifies additional flags that can be passed to Gradle (the build system used to compile Android).
This property is for advanced developers only and it is their responsibility its right usage.

By default has the following command

--deamon --parallel -Dorg.gradle.jvmargs=-Xmx$(ALLOC_SIZE)m

Where $(ALLOC_SIZE) is 2048. To disable this behavior simply remove '--daemon' flag.

  Flag Description


Indicates the usage of gradle's daemon. This speeds up following builds significantly.

  --parallel Indicates to execute build task in parallel (i.e. compile mains projects in parallel).


Indicates the JVM arguments to be used by the daemon process.
Possible arguments can be found here.
In particular, '-Xmx2048m' sets the maximum amount of memory that is able to allocate for Gradle Daemon. Android's Gradle plugin will use a special option DexInProcess when Gradle's daemon VM has enough memory allocated to speed up its build time significantly.
Note: When the Multidex Build property is enabled, the amount of memory required to enable dexInProcess increases by 1GB (since this property modifies the javaMaxHeapSize default value).
          As a consequence, when Multidex Build property is set to True, the $(ALLOC_SIZE) is set to 3GB. Otherwise, the value used is 2GB.
