Zip export did not work


i had created a test project with , i share the project as public so you can check its a simple project
then i follow the instructions of the documentation here , 2b. (Ionic v3.x) Set Up A Local Ionic Project , the content of my ionic info command on the folder of the testeando aplication is :

ionic (Ionic CLI) : 4.4.0 (/usr/local/lib/node_modules/ionic)
Ionic Framework : ionic-angular 3.9.2
@ionic/app-scripts : 3.2.0


cordova (Cordova CLI) : 8.1.2 (cordova-lib@8.1.1)
Cordova Platforms : android 7.1.4
Cordova Plugins : cordova-plugin-ionic-keyboard 2.1.3, cordova-plugin-ionic-webview 2.2.5, (and 4 other plugins)


Android SDK Tools : 26.1.1 (/linuxdata/ide/androidstudio)
NodeJS : v8.10.0 (/usr/bin/node)
npm : 3.5.2
OS : Linux 4.15

when i execute the command
testeando/ionic cordova run android --vervose
my android emulator runs well and i show a default ionic app.
then i copy the contents of the zip file inside (over) the folder src, and when i try again to execute the comand
testeando/ionic cordova run android --vervose
the emulator just shows me a white page blocked


today i made some test,
now, i just follow the 2a. (Ionic v1) Set Up A Local Ionic Project section as if my ionic where V1, and just coping the zip content into the www folder it works.
please i need you to clearify , the procedure !!1
