    The cause:

    You have got ”expiring daemon because jvm heap space is exhausted” because there is a tremendous strain placed on the Android build system when you add more modules, so the JVM memory allotted is not enough to complete your project.

    Solution:

    To solve this problem, you need to extend the configuration max heap size for your project. You can do this by 2 ways: through IDE or GUI.

    The first, by way of IDE:

    This error can be solved by adding two following lines into gradle.properties file. Moreover, you can rely on the availability of RAM to configure the memories which their size is smaller than 1.

    org.gradle.daemon=true

org.gradle.jvmargs=-Xmx2560m

    Another way is through GUI:

    Looking for “Memory Settings” in the Settings menu, then extend the IDE and Daemon maximum heap sizes in accordance with the amount of available system RAM. 

    $ man java
...
-Xmxsize
The maximum size (in bytes) of the memory allocation pool is specified here. This value 
must be more than 2 MB and a multiple of 1024. To represent kilobytes, megabytes, or 
gigabytes, respectively attach the letters k or K, m or M, or g or G. Runtime system configuration is 
used to determine the default value. -Xms and -Xmx are frequently set to the same value for 
server deployments. See the "Ergonomics" part of the Java SE HotSpot Virtual Machine Tuning 
Guide at
http://docs.oracle.com/javase/8/docs/technotes/guides/vm/gctuning/index.html.

The below examples perform the way to set the maximum enabled size of allocated memory to
80 MB using differrent units:

-Xmx83886080
-Xmx81920k
-Xmx80m

The -Xmx option is similar with -XX:MaxHeapSize.

  2. This was solved by me configuring the following for my Native project: 

    // gradle.properties
org.gradle.daemon=true
org.gradle.configureondemand=true
org.gradle.jvmargs=-Xmx4g -XX:MaxPermSize=2048m -XX:+HeapDumpOnOutOfMemoryError -Dfile.encoding=UTF-8

    And 

    // app/build.gradle
android {
 dexOptions {
 javaMaxHeapSize "3g"
 }
}
