Hmmm...another piece to the puzzle.
I intercept the HTML to see what it looks like and although the page stops
loading, when I inspect it, all I see is an empty HTML page! So for
whatever reason, the problem devices aren't getting the data loaded when I
retrieve it over the Internet.
For those who want to know how to intercept the HTML, here is what you do
just BEFORE your call to WebView.loadUrl()
// intercept calls to console.log
webview.setWebChromeClient(new WebChromeClient()
{
public boolean onConsoleMessage(ConsoleMessage cmsg)
{
// check secret prefix
if (cmsg.message().startsWith("MAGIC"))
{
String msg = cmsg.message().substring(5); // strip off
prefix
// process HTML
DebugLog.d(TAG, msg);
return true;
}
return false;
}
});
// inject the JavaScript on page load
webview.setWebViewClient(new WebViewClient() {
public void onPageFinished(WebView view, String address)
{
// have the page spill its guts, with a secret prefix
view.loadUrl("javascript:console.log('MAGIC'+document.getElementsByTagName('html')[0].innerHTML);");
//Stop the spinner
activityIndicator.setVisibility(View.GONE);
}
});
