IONIC中的APK错误生成

Question

I have tried to build apk for android in IONIC however everytime I do the build using command: ionic cordova build android it will always result to BUILD FAILED. The error is so generic it only says DeprecationWarning: Unhandled promise rejections are deprecated. Below image is the full response:

Thank you in advance for the help.

Answer 1

First, you have to open android studio->Tools->Android->SDK Manager See the screenshot below

And Applying at the time, it will ask the license. You have to accept and download the API 26. After it will work. :)

Answer 2

Unhandle Promise rejection comes mainly with Cordova version @8.0.0.

Could you downgrade the version to 7 to 6 and try to build ?
