Question

I have my phone connected to Eclipse but I can’t see logcat until phone is “fully” booted and my receiver (application) crashes before that so I’m unable to debug it. I’m sure it has to do something with context and intents :

My receiver is crashing on boot because of context problems I’m sure :

 public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Calendar c2 = Calendar.getInstance();               
    int hour = c2.get(Calendar.HOUR_OF_DAY);
    int minute = c2.get(Calendar.MINUTE);
    int sek = c2.get(Calendar.SECOND);

    int dan;
    int dodaj;

    milivreme = ((hour * 60 * 60 * 1000)+ (minute * 60 * 1000) + (sek * 1000));

    Cursor cursor = DatabaseManager.getAllData();

    cursor.moveToFirst();
    if (!cursor.isAfterLast())
    {
        do
        {               
    milibaza = cursor.getInt(3);
    razlika = milibaza - milivreme;

    Intent intent1 = new Intent(context, AlarmReceiver.class);
    PendingIntent pendingintent = PendingIntent.getService(context, 2, intent1, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE);

    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + razlika, pendingintent);
        }
        while (cursor.moveToNext());
    }
}   

Update, finally managed to catch the exception :

01-06 02:21:19.920: E/AndroidRuntime(7360): java.lang.RuntimeException: Unable to start receiver com.example.prva.OnBootReceiver: java.lang.NullPointerException

You should use Context context, don’t Context contextic.

private Context contextic;    //    NEEDLEES !
@Override
public void onReceive(Context context, Intent intent) {
    // TODO Auto-generated method stub
    Calendar c = Calendar.getInstance();                
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);
    int sek = c.get(Calendar.SECOND);
    int dan;
    int dodaj;

    milivreme = ((hour * 60 * 60 * 1000)+ (minute * 60 * 1000) + (sek * 1000));

    Cursor cursor = DatabaseManager.getAllData();

    cursor.moveToFirst();
    if (!cursor.isAfterLast())
    {
        do
        {               
    milibaza = cursor.getInt(3);
    razlika = milibaza - milivreme;

    Intent intent1 = new Intent(context, AlarmReceiver.class);
    PendingIntent pendingintent = PendingIntent.getService(context, 2, intent1, PendingIntent.FLAG_CANCEL_CURRENT);
    AlarmManager am = (AlarmManager) context.getSystemService(context.ALARM_SERVICE); //CONTEXT ! 

    am.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis() + razlika, pendingintent);
        }
        while (cursor.moveToNext());
    }}

My question for you : why did you write while (cursor.moveToNext()); (the thing is that you use semicolon after loop) ?

If my answer isn’t helpful, give please stack trace.
