Won't load on release

[bagintz]

For some reason when I do a simple flutterWebviewPlugin.launch for release it does not work, but a regular build (debug) does. I am sure I am missing something simple. Any ideas?

[hyvikk]

Can you please give more info? Plugin version, Android / iOS / both, error log if possible.

@charafau ,

I'm facing the same issue in my project. For demo, created a basic sample to load "https://google.co.nz". Git sample here.

It works perfectly in debug mode. With release APK, Webview cant load the url. Please find the screen shot below.

I think I'm missing something real small info. Any leads please?

And this on not related to #239.

I have same issue too.

it workes in profile mode

[harsha973]

Anyone got a working solution?

[harsha973]

FIXED

It's a small permission issue on Android. Added <uses-permission android:name="android.permission.INTERNET"/> to AndroidManifest.xml and webview loads url in release mode 🎉

For reference, I have a basic Git sample here

But not sure why it works in debug mode though 🤔

[charafau]

Sorry I was out for some time. Yes.. you need to have Internet permission - it's added by default in debug mode (that's why you can hot reload code) but seems like it's stripped on release mode. Closing this one!

No its still gives me error while generating apk from release mode.

[charafau]

@Maulik009 need more info, some logs, code..

[MahiMahionly]

get the Release APK from this command in terminal: ** flutter run --release **.
This Will Definitely Solve Your All Those Problems..
Also It have less MB output than Getting Release Apk from Build ->Flutter->Build Apk ...etc .
