Fix : Try increasing your swap space or increase your maximum RAM available in your system keeping 1 GB for your system to work properly. We recommend you have at least 16GB and 32 GB swap space. Otherwise, you will end up in such a situation. https://stackoverflow.com/questions/35579646/android-source-code-compile-error-try-increasing-heap-size-with-java-option

Assuming you have 16 GB of RAM below are the commands you can run before starting compilation. Please don't clean the system, it will take more time again to compile it.
