Step 1. Setup and Initialize SDK

If your android SDK version below 3.47, Please see the tutorial from this link.

Install the SDK

The CrystalExpress SDK is available through AAR or JAR :

• AAR (Recommend)

  1. Copy ce-xx-xx-x.x.aar to the libs folder of your app project

  2. Add following line to your app build.gradle. (You don't need to do add v4 support library if you already had v7 in your project)

     apply from: 'https://raw.githubusercontent.com/intowow/ce-sdk-android-config/master/aar-config.gradle'
     ...
     dependencies {
       ...
       compile 'com.android.support:support-v4:+'  
     }

  3. Declare Crystal ID received from your Intowow account manager in your Android Manifest.

     <meta-data android:name="CRYSTAL_ID" android:value="crystalidforandroidtestdontuseit" />

• JAR

  1. Copy ce-xx-xx-x.x.jar to the libs folder of your app project.

  2. Add Android v4 Support Library to your app project. (You don't need to do this step if you already added v7 support library in your project)

     dependencies {
         ...
         compile 'com.android.support:support-v4:XX.X.X'  
     }

  3. Setup Your Android Manifest

     • Declare permissions

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

     • Declare Activity

       <activity android:name="com.intowow.sdk.WebViewActivity"
                 android:configChanges="orientation|screenSize"
                 android:theme="@android:style/Theme.NoTitleBar.Fullscreen">
       </activity>

     • Declare Receiver

       <receiver android:name="com.intowow.sdk.ScheduleReceiver" 
                 android:exported="false">
                 <intent-filter >
                           <action android:name="com.intowow.sdk.prefetch"/>
                 </intent-filter>
       </receiver>

     • Declare Crystal ID received from your Intowow account manager.

       <meta-data android:name="CRYSTAL_ID" android:value="crystalidforandroidtestdontuseit" />

Initialize The SDK

1.Declare your Application in the AndroidManifest.xml.

<application android:name="Your Application">
    ...
    ...
</application>

2.Add method to your Application's onCreate

import android.app.Activity;
import android.app.Application;
import android.os.Build;
import android.os.Bundle;

import com.intowow.sdk.I2WAPI;

public class BaseApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        //  TODO
        //  init SDK
        //
        //  production mode
        //I2WAPI.init(activity);

        //  Test Mode
        //I2WAPI.init(activity, true);

        //  or open verbose log with test mode
        I2WAPI.init(activity);
    }
}
