When playing twitter video in android web view it shows the message \'by playing this video you agree to the Twitter use of cookies\' and video is not played after that.
Call loadDataWithBaseURL instead of loadData, like this:
loadDataWithBaseURL("https://mywebsite.com", mContent, "text/html", "UTF-8", null);
JavaScript is disabled in a WebView by default.
WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
UPDATED:
Use TweetView for Native Videos Launching native video support for Twitter Kit
