Firebase Database Permission denied with read/write permissions set to true

Question

I\'m having trouble writing to my Firebase database in my simple Android app. I\'ve set my database rules to be public:

{
  \"rules\": {
    \".read\": true,         


        

Answer 1

I've been changing firestore rules instead of DB... Hope it helps to someone dumb like me.

Answer 2

This looks like problem with your google-services.json.

Make sure app name and client id are same as in firebase console.

If you are not sure re-download google-services.json from your project's console and add it your project.

Answer 3

I'm not entirely sure what the problem was, but I just deleted my project from Firebase and recreated it, deleting and installing the new google-services.json and it worked perfectly the second time.

Luckily this is a test app and my database was empty, but if you're in this situation and have valuable information stored in your account, I would recommend exporting it before trying this solution.

Answer 4

Complete Solution:

1). Firstly go to Authentication Tab and select SIGN-IN-METHOD turn Anonymous On

2). Secondly go to Database Tab and write Rule

{
"rules": {
".read": true,
".write": true
}}

3). Thirdly go to Storage Tab and write following rule

service firebase.storage {
 match /b/myapplicationname-f2266.appspot.com/o {
 match /{allPaths=**} {
 allow read, write;
}}}

Note This solution is only for testing purpose with following steps you are giving public permission for Read and Write your database.

Answer 5

Okay I have tried all above solution and failed. After a while I found that my Project has 2 modules and I call firebase in the second module instead of the main one, so the solution is to add the second one to the firebase project too, and it works.

Answer 6

Maybe you should set your rules to: (I had the same problem. It works for me.)

// These rules require authentication
    {
      "rules": {
        ".read": "auth != null",
        ".write": "auth != null"
      }
    }
