AndroidStudio: Intent Problem- Return data using Intent but no working

I want to return the data from second activity to first activity using intent when click the OnAddClicked button in second activity, but what I done was not working. The data that I return to first activity is null and I have no idea about this. Can anyone help me to solve this problem?

//Intent new_intent = new Intent(context, CartList.class);

new_intent.putExtra("Quantity",invoiceDetails.getQuantity());
new_intent.putExtra("Price",invoiceDetails.getUPrice());
setResult(1, new_intent);
finish();
}
}
}

OnAddClicked your are finishing the activity when it goes to next activity previous activity goes to end....so remove the finish();

First thing first, to get result from other activity, you need to Use startActivityForResult method instead of startActivity.
Intent item_intent = new Intent(CartView.this, ItemDetail.class);
item_intent.putExtra("ItemKey",itemcode);
item_intent.putExtra("ItemUOMKey",uom);
item_intent.putExtra("Items",sa);
//startActivity(item_intent);
startActivityForResult(item_intent,REQUST_CODE);
and for setting result
Intent new_intent = new Intent();
new_intent.putExtra("Item", items);
new_intent.putExtra("Quantity",invoiceDetails.getQuantity());
new_intent.putExtra("Price",invoiceDetails.getUPrice());
setResult(Activity.RESULT_OK, new_intent);
finish();
and to receive result use below code.
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(REQUST_CODE==requestCode && resultCode==Activity.RESULT_OK){
// do logical stuff.
}
}

How to store date and time in the database using DatePicker and TimePicker (Android Studio)?

I am trying to build an app where the user selects date and time (through DatePicker and TimePicker), then presses a button called "Add Exam" which stores these information into a SQLite Database. When the user clicks on "View Exam", the date and time is supposed to show up on the screen along with other information stored in the database.
I get an error with the lines "date.getText().toString(), time1.getText().toString()" where "getText" is not being recognised.
public class Exam extends AppCompatActivity {
DatabaseManager myDb;
EditText un, loc3;
DatePicker date;
TimePicker time1;
int year;
int monthOfYear;
int dayOfMonth;
Button btnAddExam;
Button btnViewExam;

#Override

myDb = new DatabaseManager(this);

btnDeleteExam = (Button)findViewById(R.id.deleteexam);
AddExam();
ViewExam();
DeleteExam();
}
public void AddExam() {
btnAddExam.setOnClickListener(
new View.OnClickListener() {
#RequiresApi(api = Build.VERSION_CODES.O)
#Override
public void onClick(View v) {
boolean isInserted = myDb.insertDataExam(
un.getText().toString(),
loc3.getText().toString(),
date.getText().toString(),
time1.getText().toString()
);
if(isInserted == true)
Toast.makeText(Exam.this,"Data Inserted",Toast.LENGTH_LONG).show();
else
Toast.makeText(Exam.this,"Data not Inserted",Toast.LENGTH_LONG).show();
}
}
);
}
public void ViewExam() {
btnViewExam.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
Cursor res = myDb.getAllDataExam();
if(res.getCount() == 0) {
message("Error","Nothing found");
return;
}
StringBuffer buffer = new StringBuffer();
while (res.moveToNext()) {
buffer.append("Unit Name: "+ res.getString(0)+"\n\n");
buffer.append("Date: "+ res.getString(1)+"\n");
buffer.append("Time: "+ res.getString(2)+"\n");
buffer.append("Location: "+ res.getString(3)+"\n\n");
}
// Show all data
message("Exam Information",buffer.toString());
}
}
);
}
public void DeleteExam() {
btnDeleteExam.setOnClickListener(
new View.OnClickListener() {
#Override
public void onClick(View v) {
}
}
);
}
public void message(String title,String Message){
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setCancelable(true);
builder.setTitle(title);
builder.setMessage(Message);
builder.show();
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.screen5_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.home5) {
Intent intent = new Intent(Exam.this, Home.class);
startActivity(intent);
return true;
}
return super.onOptionsItemSelected(item);
}
}

You would have to get parts of the date individually
int day = datePicker.getDayOfMonth();
int month = datePicker.getMonth();
int year = datePicker.getYear();

I think your method should be like below
#Override
public boolean onQueryTextChange(String newText) {
ArrayList<ApplicationInfo> templist = new ArrayList<>();
for (ApplicationInfo temp : items){
if (temp.toString().contains(newText.toLowerCase())){
templist.add(temp);
}
}
if(templist != null && templist.size() > 0){}
ArrayAdapter<ApplicationInfo> adapter = new ArrayAdapter<>(MainActivity.this, android.R.layout.simple_list_item_1,templist);
listApps.setAdapter(adapter);
}else{
listApps.setAdapter(null);
}
return true;
};

Here, everything looks normal. But there is no the rest of the code. Maybe you create an activity every second.
I would recommend you to write in support of the admob and clarify the issues. Maybe you're lucky and they will unblock you.
