TimePicker Crashes app

Setting an Alarm from a TimePicker dialog, however, when intent is invoked the app crashes.

Here is the Code for the Dialog : 

public void clicker (View view)
{
    Calendar calendar = Calendar.getInstance();

    TimePickerDialog mTimePicker;
    mTimePicker = new TimePickerDialog(AddAlarm.this,
        new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) {
                Calendar calendar = Calendar.getInstance();
                calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour());
                calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute());

                Intent myIntent = new Intent(AddAlarm.this, AlarmReceiver.class);
                pendingIntent = PendingIntent.getBroadcast(AddAlarm.this, 0, myIntent, 0);

                alarmManager.set(AlarmManager.RTC_WAKEUP,
                    calendar.getTimeInMillis(), 
                    pendingIntent);
            }
        }, hour, minute, false);// Yes 24 hour time

    mTimePicker.setTitle("Select Time");
    mTimePicker.show();
}

Here is the logcat :

        at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:774)
        at dalvik.system.NativeStart.main(Native Method)

This is what happens when I press the ImageButton to launch the TimePicker dialog. I guess the mistake is in passing the time via intents. Any help will be appreciated.

you have done

 calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour());
 calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute());

You should use selectedHour and selectedMinute

calendar.set(Calendar.HOUR_OF_DAY, selectedHour);
calendar.set(Calendar.MINUTE, selectedMinute);

This should work, And make sure you did everything correct with imageView All the best

Try this

public void clicker (View view)
{
    Calendar calendar = Calendar.getInstance();

    final TimePickerDialog mTimePicker;
    mTimePicker = new TimePickerDialog(AddAlarm.this,
        new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker timePicker,int selectedHour, int selectedMinute) {
                timePicker = mTimepicker;
                Calendar calendar = Calendar.getInstance();
                calendar.set(Calendar.HOUR_OF_DAY, timePicker.getCurrentHour());
                calendar.set(Calendar.MINUTE, timePicker.getCurrentMinute());

                Intent myIntent = new Intent(AddAlarm.this, AlarmReceiver.class);
                pendingIntent = PendingIntent.getBroadcast(AddAlarm.this, 0, myIntent, 0);

                alarmManager.set(AlarmManager.RTC_WAKEUP,
                    calendar.getTimeInMillis(), 
                    pendingIntent);
            }
        }, hour, minute, false);// Yes 24 hour time

    mTimePicker.setTitle("Select Time");
    mTimePicker.show();
}
