Android multidex not supporting with proguard

问题

I updated all my built tools, supportlibrary and google Play services. But still I am getting the following error:

Error:Execution failed for task ':app:shrinkReleaseMultiDexComponents'

java.io.IOException: The output jar [app\build\intermediates\multi-dex\release\componentClasses.jar] must be specified after an input jar, or it will be empty.

I am able to fix this by setting minifyEnabled to false, but that is not what I want. Does anyone know how to fix it?

回答1:

Finally i able generate APK with

minifyEnabled to true

Actually the issue was some duplicate classes given some warning which i didn't noticed.

For me, i added

-dontwarn com.aphidmobile.**

in proguard-rules.pro, Same way you have to specify which libraries producing duplicate warning.

It worked Great !
