At present, Google and Baidu query there are two kinds of solutions

1. Set the Java

-xms128m
-xmx512m
-xx:maxpermsize=250m

Modify these three parameters

2. Upgrading the JDK

There's no way to test 2 options.

Pass

Dx.bat--dex

The Dx.bat script for the command has such a code

REM by default, give DX a max heap size of 1 gig and a stack size of 1meg. REM This can is overridden by using "-jxmx ..." and "-JXSS ..." options below. set defaultxmx=-xmx1024mset defaultxss=-xss1m

Set defaultxmx=-xmx1024m

The reason is that the xmx set here is 1024M, when compiling the package apk, the Java Virtual Machine memory space is not enough, modified to 512M can be compiled and packaged properly.

Set defaultxmx=-xmx1024m
