Add object in List ( Android )

i'm trying to put some intents in a List to a specific place but the app crashes 'cause of NullPointerExecption but don't understand why !

private ArrayList<PendingIntent> test;

[...]

try
{
     test.add( 42, alarm_Intent);
// I tried aswell without index ( it makes it crash too ) :
     test.add(alarm_Intent);
}
catch (Exception e)
{
     Toast.makeText(this, ""+e.toString(), Toast.LENGTH_LONG).show();
}

Here is the error :

[2014-06-08 18:30:41 - ddms] null
java.lang.NullPointerException
at com.android.ddmlib.Client.read(Client.java:698)
at com.android.ddmlib.MonitorThread.processClientActivity(MonitorThread.java:311)
at com.android.ddmlib.MonitorThread.run(MonitorThread.java:263)

What did i do wrong ?

You never called ctor of your array list and therefore it is null while calling add.

You need to initialize test.

Do it this way:

private ArrayList<PendingIntent> test = new ArrayList<PendingIntent>;

Should be

ArrayList<PendingIntent> test = new ArrayList<PendingIntent>();
