Android Volley Get JSON Data

 

1) Import Dependencies

 The easiest way to add Volley to your project is to add the following dependency to your app's build.gradle file:

dependencies {
    ...
    compile 'com.android.volley:volley:1.0.0'
}

2) Add Internet Permission On Manifest File 

<uses-permission android:name="ANDROID.PERMISSION.INTERNET" />
