Muter muter mbah gugel nyari kenapa ga bisa ngambil data dari server lewat ajax call dari aplikasi android yg dibikin pake cordova, ternyata solusinya cukup simpel saja :D

Error yg muncul di log adalah:

Refused to connect to 'http://fachrul.net/' because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

cordova Refused to connect to because it violates the following Content Security Policy directive: "default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback. 

Solusinya setelah baca dari artikel ini:
http://www.html5rocks.com/en/tutorials/security/content-security-policy/
https://github.com/apache/cordova-plugin-whitelist#content-security-policy

cukup menambahkan meta tag di dalam file .html doank, diatas semua meta tag, contohnya kayak gini:

<meta http-equiv="Content-Security-Policy" content="default-src 'self' data: gap: https://ssl.gstatic.com 'unsafe-eval'; style-src 'self' 'unsafe-inline'; media-src *; connect-src 'self' http://fachrul.net">

Ganti link merah ke domain yg km mau.

Keterangan connect-src membatasi domain yang bisa kamu lakukan koneksi lewat XHR, WebSockets, ataupun EventSource
