Phonegap can't Access My Own Api Service

I had an issue that my app can't connect to my own api at the actual or emulator android device. Anyway, my issue is resolved by following change to root config.xml

// change from this 
<access origin="*" />
// to following code
<access origin="http://*" />
<access origin="https://*" />

Now, each dev's enviromen might be different, you might encouter the same issue by fixed by different things. At the point I was fixing my issue, my phonegap is using 6.4.2, npm is 3.10.3, node version is v6.7.0, Android studio is using 2.2.2, windows OS version is 10.0.14393.

> node -v
> npm -v
> ver
> phonegap version

Some people also said they had same issue but because of missing cordova-plugin-whitelist plugin, but my phonegap is already contains that plugin, but if you don't have it, you can try to add it to see if fix your issue or not.

  <plugin name="cordova-plugin-whitelist" source="npm" spec="~1.2.1" />

I also, my issue was html's content-security-policy issue, so I defined my api over there, so make sure all my api are able to call but at the end, still failed at the android device, and after I add my temporary access origin at the root config.xml, even I removed my content-security-policy tag, still works.

<meta http-equiv="Content-Security-Policy" content="default-src 'self' .....

So, could be phonegap change something away to handler these...
