    <p>I am using Remainder in my App. I have to get the events from the database and the set the details into calendar for setting alarm with Push message. I have tried some code.</p> <p>but i could not set the calender manual. Getting Null pointer exception. My code is here:</p> <pre><code>scheduleClient = new ScheduleClient(this); scheduleClient.doBindService(); Calendar c = Calendar.getInstance(); String month = String.valueOf(c.get(Calendar.MONTH) + 1); String year = String.valueOf(c.get(Calendar.YEAR)); String months = null; if (month.startsWith("0") || month.startsWith("1")) { months = year + "-" + month; } else { months = year + "-" + "0" + month; } if (isSetToTrue == true) { LoadCalender(months); // here set your checkBox to true Toast.makeText(this, "Check box enabled", Toast.LENGTH_SHORT) .show(); } else { Toast.makeText(this, "Check box disabled", Toast.LENGTH_SHORT) .show(); } public void LoadCalender(String month) { try { Cursor cursor = null; Database db = new Database(getApplicationContext()); cursor = db.getSelectedEventDetails(month); if (cursor.getCount() != 0) { if (cursor.moveToFirst()) { do { text = cursor.getString(cursor.getColumnIndex("event")); title = "News/Events"; String dates = cursor.getString(cursor .getColumnIndex("date")); try { DateFormat formatter; Date date = new Date(); formatter = new SimpleDateFormat("yyyy-MM-dd"); date = (Date) formatter.parse(dates); SimpleDateFormat fmt = new SimpleDateFormat( "yyyy-MM-dd"); String todayStr = fmt.format(date); java.sql.Date dt = java.sql.Date .valueOf(new String(todayStr)); System.out.println("Today is " + dt); String yr = String.valueOf(dt.getYear()); int year = Integer.parseInt("20"+yr.substring(1)); int months = dt.getMonth(); int day = dt.getDay(); Calendar c1 = Calendar.getInstance(); c1.set(year, months+1, day); c1.set(Calendar.HOUR_OF_DAY, 0); c1.set(Calendar.MINUTE, 0); c1.set(Calendar.SECOND, 0); // Ask our service to set an alarm for that date, // this // activity talks to the client that talks to the // service scheduleClient.setAlarmForNotification(c1); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } while (cursor.moveToNext()); } } cursor.close(); } catch (Exception e) { e.printStackTrace(); } // looping through All Contacts } </code></pre> <p>Logcat error;</p> <pre><code> 03-19 12:23:23.395: W/System.err(2984): java.lang.NullPointerException 03-19 12:23:23.405: W/System.err(2984): at com.rathnasoft.reminder.ScheduleClient.setAlarmForNotification(ScheduleClient.java:54) 03-19 12:23:23.426: W/System.err(2984): at com.rathnasoft.vikasa.HomeActivity.LoadCalender(HomeActivity.java:228) 03-19 12:23:23.446: W/System.err(2984): at com.rathnasoft.vikasa.HomeActivity.onCreate(HomeActivity.java:87) 03-19 12:23:23.466: W/System.err(2984): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 03-19 12:23:23.475: W/System.err(2984): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1611) 03-19 12:23:23.506: W/System.err(2984): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1663) 03-19 12:23:23.518: W/System.err(2984): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 03-19 12:23:23.525: W/System.err(2984): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:931) 03-19 12:23:23.556: W/System.err(2984): at android.os.Handler.dispatchMessage(Handler.java:99) 03-19 12:23:23.577: W/System.err(2984): at android.os.Looper.loop(Looper.java:130) 03-19 12:23:23.586: W/System.err(2984): at android.app.ActivityThread.main(ActivityThread.java:3683) 03-19 12:23:23.615: W/System.err(2984): at java.lang.reflect.Method.invokeNative(Native Method) 03-19 12:23:23.635: W/System.err(2984): at java.lang.reflect.Method.invoke(Method.java:507) 03-19 12:23:23.645: W/System.err(2984): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:839) 03-19 12:23:23.666: W/System.err(2984): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:597) 03-19 12:23:23.676: W/System.err(2984): at dalvik.system.NativeStart.main(Native Method) </code></pre>

    1. COLooks like `scheduleClient` is `null`. Are you calling `LoadCalender()` from somewhere else? Offtopic: methods in Java by convention start with lower case (e.g. `loadCalendar`, not `LoadCalendar`), and it's spelled "calendAr".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
