Internal error in Firestore (0.6.6-dev) when trying to update document

Question

The following error is giving me a hard time. I'm trying to update a single field in a document stored in my Firestore project.

    E/AndroidRuntime: FATAL EXCEPTION: main

Here is my code:

FirebaseUser user = FirebaseAuth.getInstance().getCurrentUser();

if(user == null){
    Log.e(LOGTAG, "Could not upload because user is not logged in.");
    return;
}

FirebaseFirestore db = FirebaseFirestore.getInstance();
DocumentReference userRef = db.collection("users").document(user.getUid());

TextInputEditText textview = findViewById(R.id.edit_text_foo);
String enteredText = textview.getText().toString(); //implements CharSequence, thus toString() gives the correct string
userRef.update("field_foo", enteredText)
        .addOnSuccessListener(new OnSuccessListener<Void>() {
            @Override
            public void onSuccess(Void aVoid) {
                Log.i(LOGTAG, "Text successfully updated!");
            }
        })
        .addOnFailureListener(new OnFailureListener() {
            @Override
            public void onFailure(@NonNull Exception e) {
                Log.w(TAG, "Error updating text", e);
            }
        });

The error occurs everytime the method is executed. Imho, the "internal error" phrase might indicate that this is indeed a problem coming with the early beta status of the Firestore database. However, this is my first android app and I'm also new to Firebase. Any qualified valuation, any idea for a solution or any pointer?

Thanks to @hatboysam, it works now. The solution is as simple as can be:

Clear the data in the application manager on the device.

Then run the app again.
