Unity Android Plugin

1.Create a new Android application in Eclipse

• Without a theme (theme should be “None”)
• Don’t create an “Activity” or a custom launcher icon

2.Add unity JARs

• The jars are located at …Unity\Editor\Data\PlaybackEngines\Androidplayer\bin\classes.jar
• Right click on project go to Properties => Java Build Path => Libraries => Add External JARS then give the unity classes.jar path, click Order and Export tab and check classes.jar and click ok

3.Code and Export Jar

• Now we can import unity to our class using the line “import com.unity3d.player.UnityPlayer;”. Following are the class that I have written.
  


package com.myuselesswork.plugin;

import java.util.GregorianCalendar;
import com.unity3d.player.UnityPlayer;

import android.app.AlarmManager;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;

public class Yapee {

private Context context;

Yapee(){

context = UnityPlayer.currentActivity.getBaseContext();
}

public void Shedule(int x){

Long time = new GregorianCalendar().getTimeInMillis()+x;

Intent intentAlarm = new Intent(context, AlarmReciver.class);

AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

alarmManager.set(AlarmManager.RTC_WAKEUP,time, PendingIntent.getBroadcast(context,1000, intentAlarm, PendingIntent.FLAG_UPDATE_CURRENT));

}

public void ClearNotification(){

NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

nm.cancelAll();
}

}

package com.myuselesswork.plugin;

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class AlarmReciver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {

PendingIntent p = PendingIntent.getActivity(context, 0, new Intent(), 0);
NotificationManager nm = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);

Notification n = new Notification(
R.drawable.ic_launcher,
"Task Burnt down!!!",
System.currentTimeMillis()
);
n.flags |= Notification.FLAG_AUTO_CANCEL;
CharSequence from = "Task Burner";
CharSequence message = "Task Burnt!!Now you are free";

n.setLatestEventInfo(context, from, message, p);

n.vibrate = new long[] { 100, 250, 100, 500};

nm.notify(1000, n);

}

}

• Right click on project go to Export => JAVA => JAR => Next  then give a path and finish.

4.Add the plugin to unity

• Put the JAR file in the Assets\Plugins\Android folder in unity project
• Now we can access functions in the plugin.Following  are some sample code

private AndroidJavaObject m_AndroidJavaObject;

…..

m_AndroidJavaObject = new AndroidJavaObject("com.myuselesswork.plugin.Yapee");

…..

//Calling a method

m_AndroidJavaObject.Call("ClearNotification");

…..

//Calling  a method with parameters

int x =1000;
m_AndroidJavaObject.Call("Shedule",new object[]{x});

• If we need to edit the AndroidManifest.xml file we have to put the edited file in to the Assets\Plugins\Android folder

A sample project which uses this plugin: https://play.google.com/store/apps/details?id=com.myuselesswork.taskburner&hl=en

AndroidManifest

Note : This a simple sample code for a plugin to make the phone vibrate via android call  (for Makluad :)) https://drive.google.com/file/d/0ByoByqm47PspdmVSLUFqUUotams/view?usp=sharing
