我想要视频路径的实际路径，我可以使用它，我正在使用以下代码。
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
String[] mimetypes = {"video/*"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivityForResult(Intent.createChooser(intent, getString(R.string.select_option)), BROWSE_VIDEO_REQUEST);
在onActivityResult（）获取文件后，它会给我以下路径
/document/video:27948
/document/C26B-6A27:ACTION_CREATORS_Full_HD.mp4
但我想要像/storage/C26B-6A27/The_Basics_Full_HD.mp4
我尝试了其他解决方案，如下面的链接，但没有工作。
面对这个问题上面的API21和特别是三星设备。
尝试使用
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
要么
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
我已经解决了所有类型的路径问题
/document/video:27948
/document/C26B-6A27:ACTION_CREATORS_Full_HD.mp4
现在我可以从USB / SDCard / Gallery / Documents等任何地方选择任何文件，除了GoogleDrive和Dropbox等。
使用以下代码。
按钮单击
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("*/*");
String[] mimetypes = {"video/*"};
intent.putExtra(Intent.EXTRA_MIME_TYPES, mimetypes);
startActivityForResult(intent, BROWSE_VIDEO_REQUEST);
在onActivityResult（）中

// TODO Auto-generated method stub
switch (requestCode) {
case BROWSE_VIDEO_REQUEST:

} else {

注意 ：
Creating file from Uri帮了我很多忙。
