My ionic project was working perfectly without error. But when I was trying to build the ionic project using the command "ionic cordova build android". I got the following error,
Cordova Android build error "Cannot read property 'length' of undefined"
To know more detail about the error I command "ionic cordova build android --verbose" then I come
to know gradlepath value is undefined. I was already installed gradle in my PC.
Then I checked the enviroment variables path value that also perfect.
I downgrade cordova cli
npm install -g email@example.com
I also removed platform folder and added using the command.
ionic cordova platform rm android
ionic cordova platform add android
after I run the build the project same error. I searched internet no solution
Finaly I realised I was updated by Android studio 4.0.1 (windows). Previously I installed 3.0.1.
now I removed the recent one and installed the previously android studio.
Next, I closed the visual studion code and reopened it and opened my project and run build
command. The project build succeful and apk was generated in output path.
