当 WebView 处于 Activity 状态时，您的视频正在 WebView 中播放，但是当我在服务(或进程)中使用 WebView 时，您的视频开始缓冲并显示“如果播放没有很快开始，请尝试重新启动您的设备”消息。
视频在 HONOR NEM-L22(OS-marshmallow) 中播放，但在其他设备中不播放。我尝试过各种版本的 android OS( Lollipop ，kitkat)。索尼 C6802 只播放音频，看不到视频
这是代码

最佳答案
问题在于设置 webview。
然后我像这样使用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。
关于android - 在 webview 中播放 youtube 视频并且 webview 正在使用时，“如果播放没有立即开始，请尝试重新启动您的设备”，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/40591050/
