this wrapper makes usage of ion library https://github.com/koush/ion simple and with less code , it supports also caching by sqlite using this wonderful repository https://github.com/teabow/android-json-data-cache

Usage :

1 - for ion library

in build.gradle add

compile 'com.koushikdutta.ion:ion:2.+'

2 - copy the following from our library folder to your project :

a - IonWrapper.java

b - sqlite package

c - copy raw to your res folder " it is used by sqlite package "

3 - change import statements to be suitable to your package name

4 - you will find

    this.progressBar = (ProgressBar) ((Activity) context).findViewById(R.id.progressBar);

in IonWrapper.java

this is because I show ProgressBar while loading

and my layout must contains

   <ProgressBar
    android:id="@+id/progressBar"
    android:layout_width="60dp"
    android:layout_height="60dp"
    android:layout_centerInParent="true"
    android:indeterminate="true"
    android:visibility="gone"/>

if you don't want this then simply remove progressBar variable and any usage of it in

IonWrapper.java

5 - in AndroidManifest.xml

add permissions

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

I used https://github.com/teabow/android-json-data-cache

"Json data cache for Android using SQLite " repository

to cache json response

and I made some changes to it to support string response
