android - 在 Google-TV Sony 3.2 Android 程序中运行 HLS 流时如何停止(隐身)URL 抑制

Question

编辑:根据我在下面的评论，我已经能够将我的测试扩展到其他 Honeycomb 3.2 和 ICS 设备。事实上，在所有情况下，URL 都会出现，因此我可以验证自适应流。因此，这只是 Sony Blueray 的问题(当时它是我唯一的自适应流媒体支持设备)。由于这不是 3.2+ 操作系统的问题，但只有一个制造商设备，所以这不是自适应流测试的问题，我可以撤回此支持请求。

我遇到了 URL 在 locat/DDMS 中被阻止和抑制的问题。我想做的是验证我的 HLS 自适应流是否真的在适应。我打算如何做到这一点是监视 logcat 并观察被拾取的 fragment 。我遇到的问题是 URL 被抑制了，所以我不能看看发生了什么。这是我在 Logcat 中看到的 fragment 。

现在我很快将这些追溯到 chrome 框架和隐身模式。一些框架来源:http://androidxref.com/source/s?defs=kFlagIncognito&project=frameworks .

81     if (!(mFlags & kFlagIncognito)) {
 82         LOG_PRI(ANDROID_LOG_INFO, LOG_TAG, "connect to %s @%lld", uri, offset);
 83     } else {
 84         LOG_PRI(ANDROID_LOG_INFO, LOG_TAG,
 85                 "connect to <URL suppressed> @%lld", offset);

我还在 Android 3.0 中找到了一个引用，“浏览器包含的新功能可以让用户更有效地导航和组织。多个选项卡取代了浏览器窗口，新的“隐身”模式允许匿名浏览。

我认为它可能默认进入隐身模式？

现在，我不是编码员，只是在努力处理掉在我腿上的代码，但我突然意识到在 setDataSource(Context context, Uri uri) 或相关的 HTTP header 中的某处可能有一个标签/标志可以设置为打开或关闭隐身模式。那些经验丰富的 Android 程序员可能会很快弄明白。

有人能帮忙吗？

如果有帮助，我在下面提供了其他引用资料。

我们通常使用 M0n0wall .只需下载、刻录 DVD，然后在 2 端口 PC 上从中启动。一个连接到网络，另一个连接到您的 Google TV。然后，您可以随心所欲地限制网络。
