inserting Start, Stop and differenece time into sql database an android studio java language

I have wrote a code when I click on button start it show current time and turn text into stop then I click on stop it show me stop current time and calculate difference. after that I made a class to insert all these three start stop and difference into SQL database.
my problem is when I click on stop button it show me toast time added but value not added into database it show blank column into database. my database table column shows no values.

java.lang.ClassCastException: Search cannot be cast to android.app.Activity

Hi does anyone know why i am getting this error in runtime? I am unsure how to resolve it and i am new to this. Please help! I have called the Search class in my MainActivity and my app crashes when i click on the button to open it.
Here is the code used to call the Search class:
search.setOnClickListener(new View.OnClickListener() {

Your Search class is a Fragment, you cannot start it with the Intent.
Make Search to be Activity or switch between fragments using FragmentManager.

Intent intent = new Intent(MainActivity.this, Search.class);
The Intent constructor doesn't expect a Fragment class as a second Argument, Here you add Search.class which is a Fragment, but you need to have an Activity instead
Fragments can be loaded in activities using a Transaction, not an intent.

How do I pass a variable from an activity to a fragment?

I have tried using the code below but it does not work. it just returns a null value when retrieved from the fragment.

You can add or replace Fragment by calling this in your activity
// Create new fragment and transaction
Fragment newFragment = new ExampleFragment();
FragmentTransaction transaction = getFragmentManager().beginTransaction();
// Replace whatever is in the fragment_container view with this fragment,
// and add the transaction to the back stack
transaction.replace(R.id.fragment_container, newFragment);
transaction.addToBackStack(null);
// Commit the transaction
transaction.commit();
more Fragment information check this http://developer.android.com/guide/components/fragments.html
To get data from you activity you can create a method in your activity
public dataType getData() {
return data;
}
in your fragment, you can get data by calling
((YourActivityClass) getActivity()).getData();
Hope this help!!

You are setting the Bundle to the Fragment, but where are you replacing/adding the Fragment? I can't see any FragmentTransaction.
Here you have some examples: http://developer.android.com/reference/android/app/Fragment.html
"DetailsActivity" is what you need, if I'm not wrong.
Example:
When you want to start your Fragment from the Activity:
Fragment fragobj=new PathfinderAdd();
fragobj.setArguments(profileBundle);
getFragmentManager().beginTransaction().add(android.R.id.content, fragobj).commit();
Where android.R.id.content is the container for your Fragments. When you do this your Fragment will be shown and the Bundle will be received.
In your Fragment "onCreate":
if (getArguments() != null) {
Bundle bundle = this.getArguments();
user = bundle.getInt("userID");
}

How to restrict user to set date based on other date from date picker in android

So what i am doing wrong, can anyone help me please. Thanks in advance.

Just compare getTimeInMillis of Calendar
Calendar mCalendarFirst = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_frist_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_frist_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_frist_datepicker);
Calendar mCalendarSecond = Calendar.getInstance();
mSelectedCalendar.set(Calendar.YEAR, your_year_from_second_datepicker);
mSelectedCalendar.set(Calendar.MONTH, your_month_from_seconf_datepicker);
mSelectedCalendar.set(Calendar.DAY_OF_MONTH, your_day_from_second_datepicker);
if(mCalendarSecond.getTimeInMillis() <= mCalendarFirst.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Update:
For your situation use below:
if(Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis())
{
//Your second date is less than first date
//Show your dialog here.
}
Try Below code:
public void onClick(View v) {
switch (v.getId()) {
case R.id.submit:
Code.title = editTextTitle.getText().toString().trim();
Code.description = editTextDesc.getText().toString().trim();
Code.diff = Code.DueDate.getTimeInMillis()
- Code.AssignDate.getTimeInMillis();
Code.days = Code.diff / (24 * 60 * 60 * 1000);
Code.strDays = String.valueOf(Code.days);
Date assignDate = new Date(Code.AssignDate.getTimeInMillis());
Date dueDate = new Date(Code.DueDate.getTimeInMillis());
if (Code.DueDate.getTimeInMillis() <= Code.AssignDate.getTimeInMillis()){
AlertDialog.Builder myDialogBattery = new AlertDialog.Builder(
Assignment_Create.this);
myDialogBattery.setTitle("How to use Less Battery");
myDialogBattery.setMessage("hahahahahaha");
myDialogBattery.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
}
});
myDialogBattery.show();
}else
{
if (isEdit) {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.update(updateId);
this.dataManipulator.close();
} else {
this.dataManipulator = new DataManipulator(this);
this.dataManipulator.insert(Code.title, Code.description,
Code.strDays);
this.dataManipulator.close();
}
Toast.makeText(getApplicationContext(),
"Details are saved successfully", Toast.LENGTH_LONG).show();
Toast.makeText(getApplicationContext(),
"Assignment Created Succesfully", Toast.LENGTH_LONG).show();
Assignment_Create.this.finish();
}
break;
}
}

try following code. Here firstDate and secondDate are Date object
if (firstDate.after(secondDate)) { OR //secondDate.before(firstDate)
//display alert here
} else {
}

TextView timer seconds digits jumping

I have this code which simply displays a countdown clock to an event. I am having an issue with it with regards to the last seconds place jumping digits unlike a normal clock. Here is the code I am working with. Could someone please offer some guidance to where this issue may be. Kind regards.
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
new Timer().schedule(new TimerTask() {
File sdcard = Environment.getExternalStorageDirectory();
File cfgFile = new File(sdcard, "TimeTillParis/config.txt");
#Override
public void run() {
runOnUiThread(new Runnable() {
public void run() {
try {
InputStream is = new FileInputStream(cfgFile);
Properties prop = new Properties();
prop.load(is);
int mmY = Integer.parseInt(prop.getProperty("YEAR"));
int mmM = Integer.parseInt(prop.getProperty("MONTH"));
int mmD = Integer.parseInt(prop.getProperty("DAY"));
int mmH = Integer.parseInt(prop.getProperty("HOUR"));
int mmC = Integer.parseInt(prop.getProperty("MINUTE"));
int mmS = Integer.parseInt(prop.getProperty("SECOND"));
Calendar cal = Calendar.getInstance();
Date today = new Date(System.currentTimeMillis());
cal.set(Calendar.YEAR, mmY);
cal.set(Calendar.MONTH, mmM);
cal.set(Calendar.DAY_OF_MONTH, mmD);
cal.set(Calendar.HOUR_OF_DAY, mmH);
cal.set(Calendar.MINUTE, mmC);
cal.set(Calendar.SECOND, mmS);
long milliseconds = (cal.getTimeInMillis() - today.getTime());
String mD="", mH="", mM="", mS="", boxText="";
mD += (milliseconds / (1000*60*60*24));
mH += (milliseconds / (1000*60*60) % 24);
mM += (milliseconds / (1000*60) % 60);
mS += (milliseconds / 1000 % 60);
boxText += "Next visit to Paris in \n\n" +
mD + "d " +
mH + "h " +
mM + "m " +
mS + "s";
TextView textView = (TextView) findViewById(R.id.textView_date_display);
textView.setText(boxText);
} catch (FileNotFoundException e) {
String cfgNotFound="";
cfgNotFound += "config.txt not found!";
TextView textView = (TextView) findViewById(R.id.textView_date_display);
textView.setText(cfgNotFound);
//e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
}, 0, 100);
}
}

I prepared complete solution, let me know if you have some questions:
