How to set window.onerror for a webview in android

Question

I have a webview and the javascript interface is also there. How can I add a window.onerror for it? The main requirement is that when I load the webview with content the otf files are throwing some invalid tag error ("OTS parsing error: invalid version tag") and I need to capture that error.

You can call a JavaScript function from Java when you get the error:

/**
 * Executes received Java Script call
 *
 * @param command - JS call to run
 */
protected void executeJsCommand(final String command) {
        webView.evaluateJavascript(command, new ValueCallback<String>() {
            @Override
            public void onReceiveValue(final String value) {}
        });
}

protected void callOnError(String error) {
    executeJsCommand("window.onerror( " + error +" )");
}
