I have the same problem, it works normally on iOS, but on android it doesn't work.

When I change my HTML to something like

<!DOCTYPE html>
<html>
    <head>
        <meta name="viewport" content="width=device-width,initial-scale=1.0,maximum-scale=1.0,minimum-scale=1.0">
        <meta http-equiv="X-UA-Compatible" content="IE=Edge">
    </head>

    <body>
             <h1>Hello World</h1>
    </body>
</html>

it works perfectly on Android, but the example doesn't work. @SlicedSilver Do you know what it could be?

I don't know if there is any permission, or if there is any additional HTML tag

Have you copied all the files to correct directories? https://github.com/tradingview/charting-library-examples/tree/master/react-native#how-to-start---android

The files are copied to different directories for iOS and Android.

To get a more concrete answer on what the issue is, you should connect the developer tools to the web view and see what the errors are (you may need to refresh the page).

Hi Mark, I managed to solve it!

For the next people who are going to integrate charting-library with Android and are testing in a simulator, when using Webview make sure to add the androidLayerType property

If it's set to hardware like me

androidLayerType="hardware"

just change it to:

androidLayerType="software"

this should fix the problem.
