Ionic run android seems to work, but the app is no

My phone is on and in debug-mode I have confirmed this with adb devices -l. When I run ionic run android, I get the output below Ionic claims that the application is launched, but nothing happens on the phone. I use a Nexus 5 with android 4.4.4.

$ ionic run android

回答1:

Type ionic info and check which Cordova version you have installed. If you have v5.0.0 that now requires a new plugin otherwise all http requests are blocked.

Recently cordova released cordova-android 4.0 with the laster version of the cordova cli. The changes in cordova-android prevent any http request by default. There have already been a few posts about this issue. To fix this, all you have to do is add the cordova-whitelist-plugin. ionic plugin add cordova-plugin-whitelist https://github.com/apache/cordova-plugin-whitelist
see ref: https://forum.ionicframework.com/t/build-proccess-changed-and-now-cannot-call-to-api/25103

Happy hacking :)

try disabling the firewall on your machine. it worked for me and I have the same configuration as you do

回答3:

I had the same problem sometime back. The reason for that was my source files in www/ folder didn't had cordova.js included in the index.html. If someone faces this problem, do make sure to add cordova.js in the source files like
