问题
My application reached the 64k limit recently. I tried to create multiple dexes using --multidex option by adding :
exec java $javaOpts -jar "$jarpath" --multi-dex "$@"
in dx batch file.
While the build process completed successfully but upon running the application it gave DexException : Library dex files are not supported in multi-dex mode
Now what does this mean ? I searched google for this but could not find anything useful.
回答1:
The --multi-dex option to dx is incompatible with pre-dexing library projects. So if your app uses library projects, you need to disable pre-dexing before you can use --multi-dex.
That said, I have no idea why this occurred to you at runtime. This clearly is a build time failure exposed by the dx tool. Maybe what happened to you is that parts of the app were rebuild when running from the IDE, triggering the build error.
