在 Fire TV 中播放 youtube 视频的问题

Question

我正在开发一个从后端获取 youtube 视频 ID 的应用程序，它应该自动播放队列中的视频而无需用户干预。但这些是我面对不同方法的挑战。

使用 Youtube API:- 这不受 FireTV 支持，我的应用程序未在亚马逊商店中获得批准。
使用网络视图：-

当我将视频 URL 用作“https://www.youtube.com/watch?v=ajMpIN6BvQE”时，youtube 视频会自动开始播放。但是我看到了对视频的推荐，无法自动删除这些推荐

当我将视频 URL 用作“https://www.youtube-nocookie。com/embed/ajMpIN6BvQE”时，它停止显示推荐，但这里的挑战是我无法自动播放视频。它迫使用户明确点击播放按钮。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);
  }

}}

我能够通过 https://developers.google.com/youtube/iframe_api_reference 获得解决方案。添加了 Java 脚本代码并启用 Java 脚本与原生 android.
