Compiling APK

[Karol]

Hello,

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 : http://www.thewindowsclub.com/how-to-run-command-prompt-as-an-administrator

https://www.howtogeek.com/194041/how-to-open-the-command-prompt-as-administrator-in-windows-8.1/

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 .
