my BuildGraddle

    apply plugin: 'com.android.application'  android {     compileSdkVersion 23     buildToolsVersion "23.0.2"      defaultConfig {         applicationId "com.mohit.firebase"         minSdkVersion 16         targetSdkVersion 23         versionCode 1         versionName "1.0"     }     buildTypes {         release {             minifyEnabled false             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'         }     }     packagingOptions {         exclude 'META-INF/LICENSE'         exclude 'META-INF/LICENSE-FIREBASE.txt'         exclude 'META-INF/NOTICE'     } }   dependencies {     compile fileTree(dir: 'libs', include: ['*.jar'])     testCompile 'junit:junit:4.12'     compile 'com.android.support:appcompat-v7:23.1.1'     compile 'com.firebase:firebase-client-android:2.5.2+' } 

i checked my firebase url. It's Perfectly Correct.

It's because you are not authorized to the Database, check the Rules Tab in the Realtime database

If it's

{   "rules": {     ".read": "auth != null",     ".write":"auth != null"   } } 

This means only authorized user's can write and read the Data.

Changing to

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

Allows anyone to write the Database

When going for Production be sure to use the first one
