我希望可以使用视频路径的实际路径，为此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，它将为我提供以下路径，例如
/document/video:27948
/document/C26B-6A27:ACTION_CREATORS_Full_HD.mp4
但是我想要像/storage/C26B-6A27/The_Basics_Full_HD.mp4
我尝试了其他解决方案，例如下面的链接，但没有用。
在API21和特别是Samsung设备上解决此问题。
答案 0 :(得分：0)
尝试使用
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
或
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
答案 1 :(得分：0)
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，但GoogleDrive和Dropbox等除外。
使用以下代码。
在按钮上单击
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@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
switch (requestCode) {
case BROWSE_VIDEO_REQUEST:
if (resultCode == RESULT_OK) {
try {
String PathHolder = data.getData().getPath();
if (FileUtil.isFileExist(PathHolder)) { // /storage/UsbDriveA/React_Native.mp4
Log.e(TAG, "SWAPLOG PATH = exist");
if (PathHolder.endsWith(".mp4") || PathHolder.endsWith(".3gp") || PathHolder.endsWith(".avi")) {
//Found Real path
mVideoPath = PathHolder;
goToPlayVideo();
} else {
Utility.showToast(SelectVideoActivity.this, getString(R.string.select_any_video_file), Toast.LENGTH_SHORT);
}
} else { // /document/video:27948
FromSDCard(data.getData());
}
} catch (Exception e) {
e.printStackTrace();
Utility.showToast(SelectVideoActivity.this, getString(R.string.video_is_not_available), Toast.LENGTH_SHORT);
}
}
break;
}
}

注意：
Creating file from Uri对我有很大帮助。
