Why can't I see my app in the phonegap emulator?

Question

JavaScript

gulp build-app
cd www/
phonegap run android

After that, the emulator starts and I do not see my application in it. What could be the problem?
Windows 764

$ phonegap -v
6.3.0

$ npm -v
3.10.6

$ node -v
v4.5.0

$ pwd
/d/dev/client/www

$ ls
assets/     fonts/    index.html  scripts/     styles/
config.xml  icon.png  maps/       staticdata/

(sorry for the chaotic question. I’ve been doing mobile development not so long ago, most likely I indicated little information. Thanks in advance)

Answer 1

The reason turned out to be a broken application. Phonegap, unlike cordova, will run the emulator even if the build fails.

Answer 2

Have you added a platform? Enter phonegap list
