react-native-webview: Error on opening download file link on android "Domain: undefined Error code -1"

I solved it by adding proyect/android/src/AndroidManifest.xml

android:usesCleartextTraffic="true"

If it doesn’t work by adding android:usesCleartextTraffic="true".

1. You can also add android:networkSecurityConfig="@xml/network_security_config" in your android/app/src/main/AndroidManifest.xml file.

2. Creating network_security_config.xml file in android/app/src/main/res/xml

<?xml version="1.0" encoding="utf-8"?>
<network-security-config>
    <domain-config cleartextTrafficPermitted="true">
        <domain includeSubdomains="true">add your domain like www.google.com</domain>
        <domain includeSubdomains="true">or local ip address 192.168.1.101</domain>

        <trust-anchors>
            <certificates src="system" />
            <certificates src="user" />
        </trust-anchors>
    </domain-config>

    <base-config cleartextTrafficPermitted="false" />
</network-security-config>

It may ignore some cert error.

Tested in

• “react-native”: “0.63.4”
• “react-native-webview”: “^11.2.0”

And I am still looking for a way to ignore all certificate error. Especially self-signed certificate.

If anyone has a workaround solution, please share here.

PR #1221 works around this bug but I haven’t been able to get it code reviewed by maintainers…

After more investigation with @trcoffman we’ve determined this to be an underlying WebView bug. We made a very stripped down pure Android WebView app. onReceivedError is always called for the download URL, including other lifecycle methods like onPageStarted and onPageFinished.

I found a filed Chrome bug and followed up there with more details for their team.

There is potential workarounds that could be done to ignore the lifecycle methods when a download just happened, but that solution isn’t the most appealing.

same issue here… work on ios , work on simulator or expo release, not in prod…

@vpankov have you got any solutions? I am also facing the same issue.

We are experiencing the same bug as well on android.

Hi @AmitPandya007
No, I didn’t. I just added onError handler, that reload webview. So user still see error message for about 2 seconds, but file is successful downloaded and user can use app after page reloaded. So it’s not a solution of the bug, but user experience process was saved and user doesn’t need to reload the app. <WebView source={{ uri: 'http://example.page' }} ref={ref => { this.webView = ref; }} onError={ ()=>{ this.webView.reload(); } } />

same issue, i might thinking about , enable that option somewhere, its was in android stupid known as <manifest ... > <uses-permission android:name="android.permission.INTERNET" /> ... </manifest>

android:usesCleartextTraffic=“true” still not work.

Same issue. show on phone, simulator work fine.
