Question

我有以下代码来查看远程托管的视频文件：

startActivity(new Intent(Intent.ACTION_VIEW,Uri.parse(article.getLink())));

其中getLink()返回与文章相关联的视频的网址。

这种方法在Gingerbread上的设备上运行良好，但我最近在ICS上测试了应用程序，并发现了一个问题。 ICS浏览器开始加载URL，我在导航栏中看到它，但几乎立即浏览器关闭，我就回到我的应用程序的活动。

当它发生时，我得到以下堆栈跟踪：

有没有其他人看到这种行为/知道修复？

Answer 1

我尝试了一些事情，发现在intent工作中明确设置数据的数据类型。

Intent videoIntent =new Intent(Intent.ACTION_VIEW);
videoIntent.setDataAndType(Uri.parse(article.getLink()), "video/*");
startActivity(videoIntent);

注意：我在Gingerbread 2.3.6中也遇到了类似的错误。

没有看到这个，但解决方法可能是显式调用youtube应用程序（如果已安装）而不是让浏览器处理它。

/**
 * @param context
 * @param url To display, such as http://www.youtube.com/watch?v=t_c6K1AnxAU
 * @return an Intent to start the YouTube Viewer. If it is not found, will
 *         return a generic video-play intent, and system will display a
 *         chooser to ther user.
 */
public static Intent getYouTubeIntent(Context context, String url) {
  Intent videoIntent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
  final PackageManager pm = context.getPackageManager();
  List<ResolveInfo> activityList = pm.queryIntentActivities(videoIntent, 0);
  for (int i = 0; i < activityList.size(); i++) {
    ResolveInfo app = activityList.get(i);
    if (app.activityInfo.name.contains("youtube")) {
      videoIntent.setClassName(app.activityInfo.packageName, app.activityInfo.name);
      return videoIntent;
    }
  }
  return videoIntent;
}
