视频正在HONOR NEM-L22（OS-marshmallow）中播放，但在其他设备中播放。我尝试过各种版本的Android OS（棒棒糖，kitkat）。在Sony C6802中，只播放音频，视频不可见

问题在于设置webview。 然后我就像这样使用webview。
@SuppressWarnings("deprecation")
@SuppressLint({"NewApi", "JavascriptInterface"})
private void initWebView(String string) {
mWebView.setClickable(false);
mWebView.setFocusable(false);
WebSettings settings = mWebView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAllowFileAccess(true);
if (Build.VERSION.SDK_INT >= 17) {
settings.setMediaPlaybackRequiresUserGesture(false);
}
if (Build.VERSION.SDK_INT < 8) {
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
} else {
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
}
mWebView.setWebViewClient(new MyWebviewClient());
mWebView.setLayerType(2, null);
mWebView.setWebChromeClient(new MyChromwClient());
playvideo(string);
mWebView.addJavascriptInterface(new MyJavaScriptInterface(PopupiTune.this), "JSHandler");
}
并且webview开始播放YouTube视频。
