将图片上传到Firebase存储失败

Question

我试图将图片从图库上传到Firebase存储。

从图库中选取图片效果不错，但所选图片未上传到Firebase存储。

我认为问题出在我的代码中，我无法弄清楚这个模块。

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); 
     } 
    }); 

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

在我OnActivityResult，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) { 

    } 
}
