android: upload of pictures from facebook to fireabse returns 404
So, I code an android app, that takes pictures from facebook and stores them in a firebase db.
I use the graph-api to get the urls of the pictures, which works fine, since I can put the urls in a browser and the pictures appear.
Now I want to use an UploadTask to upload these pictures to firebase, and I get:
E/StorageException: StorageException has occurred.
Object does not exist at location.
Code: -13010 HttpResult: 404

Here is my upload method:
static class UploadPicAsyncWrapperTask extends AsyncTask<String, Void, Void> {
@Override
protected Void doInBackground(String... strings) {
String picsFolder = strings[0];
String id = strings[1];
final String url = strings[2];
final String profilepicNodeName = strings[3];
final String picsNodeName = strings[4];
final StorageReference filePathRoot = FirebaseStorage.getInstance().getReference().child(picsFolder).child(FirebaseAuth.getInstance().getCurrentUser().getUid());
final StorageReference filePath;
filePath = filePathRoot.child(id);
filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
// File already exists
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception exception) {
final UploadTask uploadTask;
try (InputStream is = new URL(Uri.encode(url)).openStream()) {
uploadTask = filePath.putStream(is); //Uri.fromFile(new File(url)); //Uri.parse(url) new ByteArrayInputStream()
uploadTask.addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
@Override
public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
@Override
public void onSuccess(Uri uri) {
if (profilePicName == null) {
mUserDatabase.child(profilepicNodeName).setValue(uri.toString());
profilePicName = uri.toString();
} else {
mUserDatabase.child(picsNodeName).child(Helper.imageUrlToFirebasePath(uri.toString())).setValue(uri.toString());
}
--picsRemaining;
}
});
}
});
} catch (MalformedURLException e) {
// TODO or not todo whatever
} catch (IOException e) {
// TODO or not todo whatever
}
}
});
return null;
}
}
And this is how the asyncTask is called:
new UploadPicAsyncWrapperTask().execute(getString(R.string.firebase_storage_pics_folder), id, url, getString(R.string.firebase_database_profilepic_node_name), getString(R.string.firebase_database_pics_node_name));
Anybody any idea why firebase can't catch the pictures?

So, there is nothing wrong with my code above. Since I can't ask Firebase if a picture was already uploaded to the database, I ask firebase to give me the downloadUrl of that picture and in onFailureListener, I upload the picture.
What I didn't know is, that onFailureListener implicit logs the error message above.
