I developed an Ionic 3 application. All builds in debug mode were generated correctly, but when trying to generate apk in release mode is giving error.

Ionic Info:

Ionic Info Error generating the apk: Erro I have tried deleting the node_modules folder and installing again with the npm install command.

I also tested by removing the Ios and android platforms and adding again.

Please help me out there.

From what I understand of the error, it seems to me a problem with the Node

"... withou a catch block, or by rejecting a Promise which was not Handler with . catch() ..."

Try installing an earlier version of Node through NVM to see if it works.

  • You have now given the error below: (Node:25384) Unhandledpromiserejectionwarning: Unhandled Promise rejection (rejection id: 1): Failed to prepare plug-in f or android : An Unexpected error occurred. Contact IBM support. (Node:25384) [DEP0018] Deprecationwarning: Unhandled Promise rejections are deprecated. In the Future, Promise rejections that are not handled will terminate the Node.js process with a non-zero Exit code.

  • The apk in debug mode generated normal, but in release gave other errors: Note: Some input files use or override a deprecated API. Note: Recompile with -Xlint:deprecation for Details. Note: Some input files use unchecked or unsafe Operations. Note: Recompile with -Xlint:unchecked for Details. Note: there Were 11 Duplicate class Definitions.

  • After removing the Android platform and adding again, but with version 6.15.0 worked, generated the apk in release mode. Now trying to sign apk, is giving error: keytool is not recognized as an internal command...

  • tries this: https://ionicframework.com/docs/pro/package/android.html or this: https://ionicframework.com/docs/v1/guide/publishing.html

After some researches I managed to solve, deleting the Android platform and adding again, but in version 6.15.0. Thank you all for your help.
