android - 没有从android中的文档中获取所选文件的实际视频路径

Question

我想要我可以使用的视频路径的实际路径，为此我使用以下代码。

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，它会给我下面的路径，比如

/document/video:27948
/document/C26B-6A27:ACTION_CREATORS_Full_HD.mp4

但我想要像 /storage/C26B-6A27/The_Basics_Full_HD.mp4

我已经尝试了其他解决方案，例如下面的链接，但没有用。

Get Real Path For Uri Android

在 API21 和特别是三星设备上面临这个问题。

Answer 1

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。

使用下面的代码。

点击按钮

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()

@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;

                    } else {  // /document/video:27948

Creating file from Uri对我帮助很大。
