Question

我尝试将图片从图库上传到Firebase存储。

从图库中选择图像可以正常工作，但所选图像未上传到Firebase存储。

我认为问题在于我的代码中的这个模块，我无法弄清楚。

if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {

  Uri selectedImageUri = data.getData();

  // Get a reference to store file at photos/<FILENAME>
  StorageReference photoRef = mPhotosStorageReference.child(selectedImageUri.getLastPathSegment());

  //Upload file to Firebase Storage
  photoRef.putFile(selectedImageUri)
    .addOnSuccessListener(this, new OnSuccessListener < UploadTask.TaskSnapshot > () {
      @Override
      public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

        // When the image has successfully uploaded, we get its download URL
        @SuppressWarnings("VisibleForTests")
        Uri downloadUrl = taskSnapshot.getDownloadUrl();

        // Set the download URL to the message box, so that the user can send it to the database
        Message message = new Message(null, userName, downloadUrl.toString());
        messagesDatabaseReference.push().setValue(message);
      }
    });

我通过USB在我的移动设备Moto G4（Android Nougat）上运行我的应用程序。

在我的OnActivityResult中，我修改了以下内容：

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
  super.onActivityResult(requestCode, resultCode, data);
  if (requestCode == RC_SIGN_IN) {
    if (resultCode == RESULT_OK) {
      ....
    } else if (resultCode == RESULT_CANCELED) {
      ....
    }
  } else if (requestCode == RC_PHOTO_PICKER && resultCode == RESULT_OK) {

  }
}
