[ERROR] Cordova encountered an error.
        You may get more insight by running the Cordova command above directly.

[ERROR] An error occurred while running cordova run android (exit code 1).

what I already tried to do and it not helps: 1. removed android studio and install again. 2. run these commands

cordova platform rm android
cordova platform add android
npm cache clear

3. update the sdk in android studio

nothing really helps to solve this issue.

Answer 1

For me this solved the problem:

ionic cordova platform rm android 
ionic cordova platform add android
