prompt error “localhost:8100 says gap_init:3” message while load ionic project in browser

Question

while i do changes in any page code there is a prompt message \"localhost:8100 says gap_init:3\" shown. then I clicked \'ok\' button another 5 messages shown. close browser

Answer 1

This error you get when you use the following command directly as follows:

ionic serve
and then followed by 
ionic cordova build android --prod --release

I SUGGEST TO FOLLOW THIS METHOD, IF YOU WANT TO RUN THE APP IN BROWSER

ionic serve
ionic build
ionic build --prod

This way you get www folder where you can upload to server and check the whole app in browser directly

Then follow to make the app ready for google play store

ionic serve
ionic cordova build android --prod --release

Answer 2

I entered the following command in terminal continuously and directly in one time:

ionic serve ionic build ionic build --prod

Problem got away and gap_init:3 didn't show up.

Answer 3

Delete the cordova.js from the www folder

When I had this problem, I was playing around with different Ionic / Angular versions and their build tools. The problem for me boiled down to 2 different cordova.js files being included into the page. After quite some time I realized that I had an outdated cordova.js output file in my www folder. Clearing the whole folder solved the problem.

Answer 4

I ran into the same issue. I was using ionic cordova run browser --livereload. Try changing the simulator to an iPhone in Chrome. Worked for me.

Answer 5

After trying the above answers without success, I simply deleted the www folder and ionic serve again worked as expected

Answer 6

Just disable the prompt and you are on the go.

// include this before cordova.js

prompt = function() { return false; }

With that you could just ignore the prompted message because in the webview the prompt itself are disable.
