Question

我想在我的应用中添加视频。但我有一个问题。我读了Android开发人员，发现了java代码的例子。但我不明白如何将视频放入apk中。应该走哪条路？我意识到视频应该在SD卡上，不是吗？我糊涂了。 Android开发VideoView.java：

        if (path == "") {
            // Tell the user to provide a media file URL/path.
            Toast.makeText(
                    VideoViewDemo.this,
                    "Please edit VideoViewDemo Activity, and set path"
                            + " variable to your media file URL/path",
                    Toast.LENGTH_LONG).show();

        } else {

            /*
             * Alternatively,for streaming media you can use
             * mVideoView.setVideoURI(Uri.parse(URLstring));

            mVideoView.setVideoPath(path);
            mVideoView.setMediaController(new MediaController(this));
            mVideoView.requestFocus();

        }
    }
}

您应该将原始资源放入/ res / raw文件夹，然后重建您的R类并从那里得到它们。

http://developer.android.com/guide/topics/resources/providing-resources.html

摘录：

生/
任意文件以原始形式保存。要使用原始InputStream打开这些资源，请使用资源ID（即R.raw.filename）调用Resources.openRawResource（）。

但是，如果需要访问原始文件名和文件层次结构，可以考虑在assets /目录中保存一些资源（而不是res / raw /）。资产/中的文件未获得资源ID，因此您只能使用AssetManager读取它们。

如何将视频放入apk？
