Ionic Android Build failed : Unable to start the daemon process

Question

when i'm running ionic build android --release i get an error

Error occurred during initialization of VM
Could not reserve enough space for 2097152KB object heap

Does anyone know the fix ?

no sure this might help : you can configure heap size in vm settings .. try that .. http://stackoverflow.com/questions/2294268/how-can-i-increase-the-jvm-memory — 10101010, Nov 02 '16 at 16:43
uninstall existing 32 bit JDK. this JDK by default installed in program files x86. now download (https://edelivery.oracle.com/otn-pub/java/jdk/8u191-b12/2787e4a523244c269598db4e85c51e0c/jdk-8u191-windows-x64.exe) and install 64 bit. by default it will install in program files. that's it — user10845448, Dec 29 '18 at 06:16

If you don't want to restart the command prompt, also add the variable to the current session with: SET _JAVA_OPTIONS=-Xmx512M – pasx May 02 '18 at 11:18

After changing the setting in the environment you should restart your Command Prompt CMD to update environment variables
