To display the chart in our Android app, we use the Android System WebView or the browser that is installed on the mobile device by default.
If the chart is not displayed or any functions on it do not work, it’s most likely that you are using old versions of these apps on your device.
To solve this problem, you need to follow these steps:
1. Update Android System WebView (if possible).
2. Update the system browser on your device, as well as the Google Chrome browser.
3. Completely turn off TradingView and turn it back on.
