Webview android not saving cookies

[h3thal]

y to log in from the webview on Android, after the next entry in the application, you must log in again. IOS doesn't have this problem.

Create a webview component specify a link to any site with authorization, for example github. specify parameters for the operation of cookies (sharedCookiesEnabled={true},thirdPartyCookiesEnabled={true}).
Then go to the application and complete the authorization. After authorization, restart the application and check authorization

It will be possible to continue working under an authorized user as on iOS

If applicable, add screenshots to help explain your problem.

Environment:

• OS: Android
• OS version: 11
• react-native version: 0.68.2
• react-native-webview version: 11.18.1

does it work when you switch to an other "real page" (i.e not just navigating inside a single page app)

we've seen on our side that on our multipage app we were able to reproduce this when we stayed on the same page

Hello, I have the same issue on android, after running inside webview:

document.cookie = `${key}=${value}`;

Checking document.cookie again returns ""

I'm setting:

<WebView
        source={{
          uri: 'file:///android_asset/Web.bundle/index.html',
        }}
        sharedCookiesEnabled={true}
        thirdPartyCookiesEnabled={true}

Testing it with https://developer.mozilla.org/en-US/docs/web/api/document/cookie actually works, so looks like it's related with using file:///

Injecting doesn't work neither:

webViewRef.current?.injectJavaScript(
      `
        (function() {
          document.cookie = "test1=Hello";
          console.log(document.cookie) // ---> ''
        })();
      `,
    );

For those with extra time or hurries, I solved it by using JS injection and EncryptedStorage.

Short description of the proposal RoboSats/robosats#258

And some key points on our implementation

1. Send cookie data to native: https://github.com/Reckless-Satoshi/robosats/blob/main/frontend/src/services/System/SystemNativeClient/index.ts#L32
2. Receiving, storing the data and injecting it back to JS: https://github.com/Reckless-Satoshi/robosats/blob/main/mobile/App.tsx#L107
3. Receiving the data back and storing it on memory to avoid data inconsistencies and async read: https://github.com/Reckless-Satoshi/robosats/blob/main/frontend/src/services/Native/index.ts#L42

Extra hint: recovering stored data on start: https://github.com/Reckless-Satoshi/robosats/blob/main/mobile/App.tsx#L34

I am sharing the temporary solution that solved my problem.

Environment Overview:

The environment of my app is an app that provides the entire service by displaying one URL through a single react native webview.

Encountered Problem:

1. Implement login logic with cookies - Login (save cookies), logout (remove cookies), automatic login (determine the presence of cookies when running the app)
2. Works well on web and iOS.
3. If you close the app immediately after logging in or logging out on Android and then run the app again, cookies remain or are not saved, causing a problem where you remain logged in even after logging out or are unable to automatically log in even after logging in.
4. If you log in or log out and leave the app open for 5 minutes, close it and run it again, the cookies will be reflected well.

Identified Cause:

The reason is that in web views of certain versions of Android or higher, cookies are automatically synchronized every 5 minutes, but when less than 5 minutes have passed, the synchronization was not done and the cookies were not reflected.

Temporary Solution:

The solution was to manually synchronize cookies in the Android Webview when cookie-related logic was executed on my web.
My easiest solution is to use the CookieManager.flush() method from the @react-native-cookies/cookies library.
When cookie logic is executed on the web, you can set it to send communication to the Webview, receive an event from Webview onMessage, and execute CookieManager.flush(). You can then synchronize manually.

Cookies are applied well after synchronization.
