    While preparing “production” version, I get this error, please help.

    Thank you in advance.

    C:\Users\KRZYSZTOF\3kurs>ionic cordova build –release android
    > cordova platform add android –save
    Using cordova-fetch for [email protected]~7.0.0

    (node:2040) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 1): CordovaError: Failed to fetch platform [email protected]~7.0.0
    Probably this is either a connection problem, or platform spec is incorrect.
    Check your connection and platform name/version/URL.
    Error: cmd: Command failed with exit code ENOENT
    (node:2040) [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.



    Well this issue is appearing due to two reasons :

    1. permissions to access files from project were not given while running that command

    2. or android platform is not installed .

    follow these steps :

    1. First of all if you are on windows Os run your command prompt as an administrator :

    if you are on mac then try adding ‘ sudo ‘ in the beginning of each command .

    2. Navigate to your ionic project folder .

    Then run following commands :

    ionic cordova platform rm android

    ionic cordova platform add android

    Then generate the resources  :

    ionic cordova resources

    then generate apk .
