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 .
