在Fire TV中播放youtube视频时出现问题

问题描述

我正在开发一个从后端获取youtube视频ID的应用，它应自动播放队列中的视频，而无需用户干预。但这是我面对不同方法所面临的挑战。

1. 使用Youtube API：-FireTV不支持此功能，并且我的应用未在亚马逊商店中获得批准。

2. 使用Webview：-

• 当我将视频网址用作“ https://www.youtube.com/watch?v=ajMpIN6BvQE”时，YouTube视频会自动开始播放。但是我看到了视频中的建议，无法自动摆脱这些建议

• 当我将视频URL用作“ https://www.youtube-nocookie.com/embed/ajMpIN6BvQE”时，它停止显示建议，但是这里的挑战是我无法自动播放视频。这迫使用户显式单击播放按钮。下面是我使用的代码

  import android.app.Activity;
  import android.graphics.Bitmap;
  import android.graphics.BitmapFactory;
  import android.os.Bundle;
  import android.view.View;
  import android.webkit.WebChromeClient;
  import android.webkit.WebSettings;
  import android.webkit.WebView;
  import android.webkit.WebViewClient;
  import android.widget.FrameLayout;
  
  public class WebViewActivity extends Activity {
    WebView webView;
    WebChromeClient.CustomViewCallback customViewCallback;
  @SuppressLint("SetJavaScriptEnabled")
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_webview);
    webView = findViewById(R.id.webView);
    webView.setWebViewClient(new WebViewClient());
    ChromeClient chromeClient = new ChromeClient();
    webView.setWebChromeClient(chromeClient);
  
    WebSettings webSettings = webView.getSettings();
    webSettings.setJavaScriptEnabled(true);
    webSettings.setAllowFileAccess(true);
    webSettings.setAppCacheEnabled(true);
  
  
    // webView.loadUrl("https://www.youtube-nocookie.com/embed/ajMpIN6BvQE");
    webView.loadUrl("https://www.youtube.com/watch?v=ajMpIN6BvQE");
    webSettings.setmediaplaybackRequiresUserGesture(false);
    webView.setWebViewClient(new WebViewClient() {
        @Override
        public void onPageStarted(WebView view,String url,Bitmap favicon) {
            super.onPageStarted(view,url,favicon);
        }
  
        @Override
        public void onPageFinished(WebView view,String url) {
            super.onPageFinished(view,url);
  
        }
    });
  }
  
  @Override
  public void onPause() {
    webView.onPause();
    super.onPause();
  }
  
  @Override
  public void onDestroy() {
    webView.destroy();
    super.onDestroy();
  }
  
  @Override
  public void onStop() {
    super.onStop();
  }
  
  @Override
  protected void onRestart() {
    super.onRestart();
  }
  
  public void onBackpressed() {
    webView.stopLoading();
    finish();
  }
  
  @Override
  protected void onStart() {
    super.onStart();
  }
  
  public class ChromeClient extends WebChromeClient {
    protected FrameLayout mFullscreenContainer;
    private View mCustomView;
    private WebChromeClient.CustomViewCallback mCustomViewCallback;
    private int mOriginalOrientation;
    private int mOriginalsystemUIVisibility;
  
    ChromeClient() {
    }
  
    public Bitmap getDefaultVideoPoster() {
        if (mCustomView == null) {
            return null;
        }
        return BitmapFactory.decodeResource(getApplicationContext().getResources(),2130837573);
    }
  
    @Override
    public void onHideCustomView() {
        ((FrameLayout) getwindow().getDecorView()).removeView(this.mCustomView);
        this.mCustomView = null;
        getwindow().getDecorView().setsystemUIVisibility(this.mOriginalsystemUIVisibility);
        setRequestedOrientation(this.mOriginalOrientation);
        this.mCustomViewCallback.onCustomViewHidden();
        this.mCustomViewCallback = null;
    }
  
    @Override
    public void onShowCustomView(View paramView,WebChromeClient.CustomViewCallback paramCustomViewCallback) {
        if (this.mCustomView != null) {
            onHideCustomView();
            return;
        }
        this.mCustomView = paramView;
        this.mOriginalsystemUIVisibility = getwindow().getDecorView().getsystemUIVisibility();
        this.mOriginalOrientation = getRequestedOrientation();
        this.mCustomViewCallback = paramCustomViewCallback;
        ((FrameLayout) getwindow().getDecorView()).addView(this.mCustomView,new FrameLayout.LayoutParams(-1,-1));
        getwindow().getDecorView().setsystemUIVisibility(3846 | View.SYstem_UI_FLAG_LAYOUT_STABLE);
    }
  
  }}
  

解决方法

我能够使用https://developers.google.com/youtube/iframe_api_reference实现解决方案。添加了Javascript代码，并启用了Java Script与Native android之间的交互。
