404 error when debugging Cordova in Chrome inspect page about cordova-android

[girotomas]

In my case, my device was connected to the internet but my computer wasn't. Connecting my computer to the internet fixed this problem.

Check your internet connection.

@weixingsun Try renaming your file from main.html to index.html. Cordova is trying to load index.html, but can't find it, which is what would cause this 404.

I also encountered this problem. Find out it was because of network blocking issue in China. Once I switched the browser proxy on, 404 error disappeared.

What do you mean exactly? Where does this 404 come from? Best post a screenshot of it here. You can just paste an image from the clipboard and it will upload and embed it in the comment.

[weixingsun]

Thanks for your reply, screenshot attached. and this is the brief information
OS: MacOS High Sierra 10.13.6
Chrome Version 67.0.3396.99 (64-bit)
Android 7.0 (ZUI 3.1.117)

That's a new one for me.

How exactly did you build your app?
Does the app work on the device itself?
Can you try another Android device?

[weixingsun]

app building cmd: cordova build android --debug
app install cmd: adb install -r platforms/android/build/outputs/apk/armv7/debug/android-armv7-debug.apk
I use this app to debug a simple usb device, and it works pretty well, and I want to change a page on it
I tried another android device, the same error

Thanks for your help, I really appreciate it

Another computer then maybe?

I google the error a bit, maybe have a look at this:

I tried on my Mac Air, Mac Pro, Windows 10, Windows 7
And I installed this app on Android 4.4, Android 7.0
All the same 404, how do I do, then ?

[janpio]

Difficult to say as it seems to be a Chrome bug. Find a computer with an older Chrome version maybe?

@weixingsun China blocked Google.

[pallaviMN]

@weixingsun , have you got any solution. Even i am facing this issue

In my case, my device was connected to the internet but my computer wasn't. Connecting my computer to the internet fixed this problem.

In my case it was because i was running a VPN-Client

Closing since doesn’t look like a cordova bug but a connection problem.

I also encountered this problem. Find out it was because of network blocking issue in China. Once I switched the browser proxy on, 404 error disappeared.

I didnt believe at first, because google services not blocking in my Country. But I launch VPN and all works. Why?
How to check which network services is needed for chrome devtools?
I can connect to google cloud, google photos and other services via browser
