Android firebase database permission denied despite the fact that a user is logged in
Question
I've never used firebase database and I think I'm having some "newbie" problems and I just can't solve it. Getting to the point:
My database is structured like this:
database
/cookbooks
/key: cookbook id, value: CookBook.class
/recipes
/recipes
/key: recipe id, value: Recipe.class
/ users
/cookbooks
/cookbook id
What I want to achieve is that on start of the app data is downloaded from those repositories (from all of them) and stored in a DataManager class.
Below are the rules in my database:
{
"rules": {
"recipes-309da": {
"cookbooks": {
".read": "auth != null",
".write": "auth != null",
},
"recipes": {
".read": "auth != null",
".write": "auth != null",
},
"users": {
"$uid": {
".read": "auth != null",
".write": "auth != null",
}
}
}
}
}
The problem is that I'm keep getting "Permission denied" notification. Data is not being downloaded nor I can save any data to the database.
I would be grateful for any help you could give me!
Some relevant code:
public static final String STORAGE_PATH_PHOTOS_UPLOADS = "photos_uploads/";
public static final String DATABASE_PATH_PHOTOS_UPLOADS = "photos_uploads";
public static final String DATABASE_PATH_RECIPES_UPLOADS = "recipes";
public static final String DATABASE_PATH_COOKBOOKS_UPLOADS = "cookbooks";
public static final String DATABASE_PATH_USERS = "users";
private StorageReference mStorageReference = FirebaseStorage.getInstance().getReference();
private DatabaseReference mDatabasePhotosUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_PHOTOS_UPLOADS);
private DatabaseReference mDatabaseRecipesUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_RECIPES_UPLOADS);
private DatabaseReference mDatabaseCookBooksUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_COOKBOOKS_UPLOADS);
private DatabaseReference mDatabaseUsersUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_USERS);
private DatabaseReference mDatabaseRecipesUploadsBelowUser = mDatabaseRecipesUploads.child(FirebaseAuth.getInstance().getCurrentUser().getUid());
private DatabaseReference mDatabaseCookBooksKeyUploadsInUserBooks = mDatabaseUsersUploads.child(FirebaseAuth.getInstance().getCurrentUser().getUid()).child("books");
At start of MainActivity I use a method attachListeners(ALL) from GeneralDataManager.
public void attachListeners(int staticIntFromGeneralUploader) {
// attaches and detaches SingleValueEventListeners so it can download data while opening an app
mDatabaseRecipesUploadsBelowUser.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
mCurrentUserRecipesList = new ArrayList<>();
mCurrentUserRecipeTitleKeyMap = new HashMap<>();
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
Recipe recipe1 = snapshot.getValue(Recipe.class);
mCurrentUserRecipesList.add(recipe1);
mCurrentUserRecipeTitleKeyMap.put(recipe1.getTitle(), snapshot.getKey());
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
mDatabaseCookBooksUploads.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
mRecipesInCookBooksMap = new HashMap<>();
for (DataSnapshot snapshotOfCookBooks : dataSnapshot.getChildren()) {
String cookBookKey1 = snapshotOfCookBooks.getKey();
if (mCurrentUserCookBookKeyTitleMap.containsKey(cookBookKey1)) {
CookBook cookbook1 = snapshotOfCookBooks.getValue(CookBook.class);
for (DataSnapshot snapshotOfRecipesInsideCookBooks : snapshotOfCookBooks.getChildren()) {
if (snapshotOfRecipesInsideCookBooks.getValue() == Recipe.class) {
Recipe recipe1 = snapshotOfRecipesInsideCookBooks.getValue(Recipe.class);
if (!mRecipesInCookBooksMap.containsKey(cookbook1)) {
mRecipesInCookBooksMap.put(cookbook1, new ArrayList<Recipe>());
mRecipesInCookBooksMap.get(cookbook1).add(recipe1);
} else {
mRecipesInCookBooksMap.get(cookbook1).add(recipe1);
}
}
}
}
}
for (CookBook logCookBook : mRecipesInCookBooksMap.keySet()) {
for (Recipe logRecipe : mRecipesInCookBooksMap.get(logCookBook)) {
Log.e("R inside C", "CookBook " + logCookBook.getTitle() + " containts Recipe: " + logRecipe.getTitle());
}
}
// attaches listener so that fragment displaying cookbooks receives arraylist containing cookbooks
if (mRecipesInCookBooksMap != null && mRecipesUpdateListener != null) {
mRecipesUpdateListener.onMapChanged((HashMap<CookBook, ArrayList<Recipe>>) mRecipesInCookBooksMap);
}
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
mDatabaseCookBooksKeyUploadsInUserBooks.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
mCurrentUserCookBookKeyTitleMap = new HashMap<>();
for (DataSnapshot snapshot : dataSnapshot.getChildren()) {
String key1 = snapshot.getKey();
String title1 = snapshot.getValue(String.class);
mCurrentUserCookBookKeyTitleMap.put(key1, title1);
}
Log.e("CurrentUserCookBook", "Updated" + mCurrentUserCookBookKeyTitleMap.keySet());
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
if (staticIntFromGeneralUploader == GeneralDataManager.RECIPE_UPDATES_LISTENER) {
mDatabaseRecipesUploadsBelowUser.addValueEventListener(recipeUpdatesListener);
} else if (staticIntFromGeneralUploader == GeneralDataManager.COOKBOOK_UPDATES_LISTENER) {
mDatabaseCookBooksKeyUploadsInUserBooks.addValueEventListener(cookBookKeysInUserBooksUpdatesListener);
} else if (staticIntFromGeneralUploader == GeneralDataManager.RECIPE_IN_COOKBOOK_UPDATES_LISTENER) {
mDatabaseCookBooksUploads.addValueEventListener(cookBookDatabaseListener);
} else if (staticIntFromGeneralUploader == GeneralDataManager.ATTACH_ALL_LISTENERS) {
mDatabaseRecipesUploadsBelowUser.addValueEventListener(recipeUpdatesListener);
mDatabaseCookBooksKeyUploadsInUserBooks.addValueEventListener(cookBookKeysInUserBooksUpdatesListener);
mDatabaseCookBooksUploads.addValueEventListener(cookBookDatabaseListener);
}
}
Part of MainActivity:
@Override
protected void onStart() {
super.onStart();
// new ImageLoadTask(imageUrl, mProfilePicture).execute();
//Referring to the name of the User who has logged in currently and adding a valueChangeListener
myFirebaseRef.child(mUid).child("name").addValueEventListener(new ValueEventListener() {
//onDataChange is called every time the name of the User changes in your Firebase Database
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
//Inside onDataChange we can get the data as an Object from the dataSnapshot
//getValue returns an Object. We can specify the type by passing the type expected as a parameter
String data = dataSnapshot.getValue(String.class);
GeneralDataManager.getInstance().attachListeners(GeneralDataManager.ATTACH_ALL_LISTENERS);
}
//onCancelled is called in case of any error
@Override
public void onCancelled(FirebaseError firebaseError) {
Toast.makeText(getApplicationContext(), "" + firebaseError.getMessage(), Toast.LENGTH_LONG).show();
mAuth.signOut();
}
});
}

I looked deeper into the problem and found the solution this morning. It's quite easy and I have no idea why I haven't came up with it earlier.
The problem was with the rules.
These are old rules:
{
"rules": {
"recipes-309da": {
"cookbooks": {
".read": "auth != null",
".write": "auth != null",
},
"recipes": {
".read": "auth != null",
".write": "auth != null",
},
"users": {
"$uid": {
".read": "auth != null",
".write": "auth != null",
}
}
}
}
}
Method I used to create user was:
mRef.child("users").child(userId).setValue(user);
The result was obvious - access to /users was restricted to users, thus no user could effectively sign in to database...
I changed it and now it works perfectly fine. Below I put new, updated code. Great thanks for all help you provided me with.
{
"rules": {
"users": {
"$uid": {
".read": true,
".write": true,
"books": {
".read": "auth != null",
".write": "auth != null",
}
}
},
"recipes": {
"$uid": {
".read": "auth != null",
".write": "auth != null",
}
},
"cookbooks": {
".read": "auth != null",
".write": "auth != null",
}
}
}
