Error during ionic build

Ionic Framework ionic-v3
1

Hi, I’m trying to build the apk but I got this:
Execution failed for task ‘:app:transformDexArchiveWithExternalLibsDexMergerForDebug’.

Thanks in advance

I’m not sure but maybe you updated your Android Studio or cordova-android to 6.4.0 or higher. Try with 6.3.0 and do a fresh install and build again.

I’m using cordova-android 7.0, btw I’ll try update/ reinstall android studio;

4

Try downgrading to cordova-android 6.3.0, thats the problem

Or upgrade to the most recent version that has all the bug fixes and support the newest Android versions: https://ionic.zone/cordova/update (Cordova Android currently is 7.1.0)

(Post your ionic info output if you want more help debugging this please)

The weird thing is before I update Angularfire and firebase it works well… and the problem just happens when I try to build or run (ionic serve still working)
