如何将视频文件发送到Firebase数据库＆amp;在Android中存储？

Question

我正在制作照片和视频共享Android应用，并使用Firebase作为我的数据库和存储。在我的ShareActivity中，用户可以选择图像捕获或录像机，并将其发送到数据库+存储。使用图像时一切正常但无法发送视频文件。 以下是我的ShareActivity代码

private static final String TAG = "Camera Tag";
private DatabaseReference mDatabaseShare;
private StorageReference mStorageShare;
private EditText mTitle;
private ImageView mTitleImage;
private Button bShare;
private Button mRecordBtn;
private Uri mFileUri;

private ProgressDialog mProgress;
private VideoView mVideoView;
// Activity request codes
private static final int CAMERA_CAPTURE_IMAGE_REQUEST_CODE = 100;
private static final int CAMERA_CAPTURE_VIDEO_REQUEST_CODE = 200;
public static final int MEDIA_TYPE_IMAGE = 1;
public static final int MEDIA_TYPE_VIDEO = 2;

// directory name to store captured images and videos
private static final String IMAGE_DIRECTORY_NAME = "Media Files";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_share);

    mTitle = (EditText) findViewById(R.id.title);
    // imageview to start camera
    mTitleImage = (ImageView) findViewById(R.id.titleimage);
    // pushes data to firebase
    bShare = (Button) findViewById(R.id.btnshare);
    // Videoview for preview
    mVideoView = (VideoView) findViewById(R.id.uservid);
    // starts video recording
    mRecordBtn = (Button) findViewById(R.id.buttonrecord);

    mDatabaseShare = FirebaseDatabase.getInstance().getReference().child("SharedMedia");
    mStorageShare = FirebaseStorage.getInstance().getReference();

    mDatabaseShare.keepSynced(true);

    mProgress  = new ProgressDialog(this);

    mTitleImage.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showImagePicker();
        }
    });

    bShare.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            shareMedia();
        }
    });

    mRecordBtn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            recordVideo();
        }
    });
}

private void recordVideo() {

    Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

    mFileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO);

    // set video quality
    // 1- for high quality video
    intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);

    // start the video capture Intent
    startActivityForResult(intent, CAMERA_CAPTURE_VIDEO_REQUEST_CODE);
}

private void showImagePicker() {

    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    mFileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

    intent.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);

    // start the image capture Intent
    startActivityForResult(intent, CAMERA_CAPTURE_IMAGE_REQUEST_CODE);

}

private Uri getOutputMediaFileUri(int mediaTypeImage) {


    return  Uri.fromFile(getOutputMediaFile(mediaTypeImage));
}

// Button click method to send data to firebase
private void shareMedia() {

    final String name_title = mTitle.getText().toString().trim();
    mProgress.setMessage("Please wait");
    mProgress.show();


    if (!TextUtils.isEmpty(name_title) && mFileUri != null){

        StorageReference filepath = mStorageShare.child("Shared_Media").child(mFileUri.getLastPathSegment());

        filepath.putFile(mFileUri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                Uri downloadUrl = taskSnapshot.getDownloadUrl();
                DatabaseReference newShare = mDatabaseShare.push();

                newShare.child("image").setValue(downloadUrl.toString());
                newShare.child("video").setValue(downloadUrl.toString());

                mProgress.dismiss();
                startActivity(new Intent(ShareActivity.this,MainActivity.class));

            }
        });

    }


}
