I\'m testing Ionic 3 app on a genymotion emulator. Btw http request doesn\'t work because of CORS. I thought that a sever has a problem. But I confirmed that a server has no pro
under your config.xml give the location of your localhost
eg:
<content src="http://10.10.1.1:8100" />
<access origin="http://10.10.1.1:8100" />
<allow-navigation href="http://10.10.1.1:8100" />
further more make sure you add the proxy url under ionic.config.json
"proxies": [{
"path": "/rest",
"proxyUrl": "http://10.10.10.1:8081/rest"
}]
