エラーfirebase.storage.UploadTask。 <init>（不明なソース）とfirebase.storage.StorageReference.putFile（不明なソース）

Question

エラーfirebase.storage.UploadTask.<init>(Unknown Source) and firebase.storage.StorageReference.putFile(Unknown Source) ..... このエラーが表示されたら、ref.putFile（imgUri）をマークします。私の間違いが起こったところで助けてください。

 //Get the storage reference 
     StorageReference ref = mStorageRef.child(FB_STORAGE_PATH + System.currentTimeMillis() + "." + getImageExt(imgUri)); 

     //Add file to reference 

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


       //Dimiss dialog when success 
       dialog.dismiss(); 
       //Display success toast msg 
       Toast.makeText(getApplicationContext(), "Image uploaded", Toast.LENGTH_SHORT).show(); 
       ImageUpload imageUpload = new ImageUpload(txtImageName.getText().toString(), taskSnapshot.getDownloadUrl().toString()); 

       //Save image info in to firebase database 
       String uploadId = mDatabaseRef.push().getKey(); 
       mDatabaseRef.child(uploadId).setValue(imageUpload); 

      } 
     }) 
       .addOnFailureListener(new OnFailureListener() { 
        @Override 
        public void onFailure(@NonNull Exception e) { 

         //Dimiss dialog when error 
         dialog.dismiss(); 
         //Display err toast msg 
         Toast.makeText(getApplicationContext(), e.getMessage(), Toast.LENGTH_SHORT).show(); 
        } 
       }) 
       .addOnProgressListener(new OnProgressListener<UploadTask.TaskSnapshot>() { 

        @Override 
        public void onProgress(UploadTask.TaskSnapshot taskSnapshot) { 

         //Show upload progress 

         double progress = (100 * taskSnapshot.getBytesTransferred())/taskSnapshot.getTotalByteCount(); 
         dialog.setMessage("Uploaded " + (int) progress + "%"); 
        } 
       }); 
    } else { 
     Toast.makeText(getApplicationContext(), "Please select image", Toast.LENGTH_SHORT).show(); 
    } 
}
