really would appreciate your help


Thanks for your screenshot.Could you please improve your code to this:
}catch(Exception e) {
String error = e.getMessage(); //instead of String error = e.toString();
...
So we can see the actual cause.
Can you please make the "don't works" dialog large? I think some text is being trimmed.
I believe you are trying to parse an empty string "".

How to proceed if cursor is empty or null

I have a sqlite database which I want to query and retrieve some values if they exist, in case they don't exist make a toast.
For this porpoise I have the next code which will call a function to create the cursor and in case this is not empty it will retrieve the information in the edittext otherwise it will make a toast:
private String lookforelementID() {
// TODO Auto-generated method stub
int ElementRequest=0;
ElementRequest = Integer.parseInt(eTElementNumb.getText().toString());
try{
database db = new database(this);
db.open();
String passedReg = getIntent().getStringExtra(MainActivity.ID_STUDY);
String returnedInfo1 = db.elementID(ElementRequest, passedReg, 0);
if (returnedInfo1.matches("")){
Toast.makeText(getApplicationContext(), "No Exist this Element", Toast.LENGTH_SHORT).show();
}else{
eTIDElement.setText(returnedInfo1);
String returnedInfo2 = db.elementID(ElementRequest, passedReg, 2);
eTElementCode.setText(returnedInfo2);
String returnedInfo3 = db.elementID(ElementRequest, passedReg, 3);
eTElementDecription.setText(returnedInfo3);
}
db.close();
}catch(ClassCastException e){
e.printStackTrace();
}
eTElementNumb.setText("");
return null;
}
The function with the cursor is as follows:
public String elementID(int elementRequest, String idStudy, int i) {
// TODO Auto-generated method stub
String[] columns = new String[]{ KEY_ROWELEMENTID, KEY_STUDYID, KEY_ELEMENTCODE, KEY_ELEMENTNAME};
Cursor c = ourDatabase.query(DATABASE_TABLEELEMENTS, columns, KEY_ELEMENTCODE + "=" + elementRequest + " AND " + KEY_STUDYID + "=" + idStudy, null, null, null, null);
String ElementInformation = null;
if(c != null){
c.moveToFirst();
ElementInformation = c.getString(i);
}
return ElementInformation;
}

The problem is in your SqlHandler.selectQuery() that returns a null, and another problem here checking the result:
if (c1 != null & c1.getCount() != 0)
You're using bitwise and & and not the short-circuiting logical and &&. Without short circuiting the complete expression including c1.getCount() on a null reference is evaluated.

There is too much here to explain it all, so I will give you the flaws causing a null pointer exception.
I can see your method of programming is coming from worrying too much about closing things and clearing up
resources to a point, it's causing problems.
contactList = new ArrayList<ContactListItems>();
// You are clearing your list, it should be empty, you have just created it.
contactList.clear();
String query = "SELECT * FROM PHONE_CONTACTS ";
Cursor c1 = SqlHandler.selectQuery(query);
// As mentioned by the other answer. You need && not &
// if (c1 != null & c1.getCount() != 0) {
if (c1 != null && c1.getCount() != 0) {
// Move to the first entry.
c1.moveToFirst();
//if (c1.moveToNext()) {
// do {
// Continue while it has not passed the last entry.
while (!cursor.isAfterLast())
contactListItems = new ContactListItems();
contactListItems.setSlno(c1.getString(c1.getColumnIndex("slno")));
contactListItems.setNameofevent(c1.getString(c1.getColumnIndex("nameofevent")));
contactListItems.setDtofevent(c1.getString(c1.getColumnIndex("dtofevent")));
contactListItems.setTimeofevent(c1.getString(c1.getColumnIndex("timeofevent")));
contactListItems.setDuration(c1.getString(c1.getColumnIndex("duration")));
contactList.add(contactListItems);
// Move the cursor along to the next entry.
cursor.moveToNext();
}
}
// Close cursor after while and within if (so you know it is not null).
c1.close();
}
else
{
// You can't close c1 if it is Null. This will throw and error. Lose the else.
c1.close();
}
// Move this to within your if statment.
c1.close();
From your code you provided in the chat.
Don't open and close your database continuously, just close each cursor you use when you're done. Just open it at the beginning and end of your program run.
public static Cursor selectQuery(String query) {
Cursor c1 = null;
try {
if (sqlDatabase.isOpen()) {
// You are closing the database.
sqlDatabase.close();
}
sqlDatabase = dbHelper.getWritableDatabase();
c1 = sqlDatabase.rawQuery(query, null);
} catch (Exception e) {
System.out.println("DATABASE ERROR " + e);
}
return c1;
}
There are many other flaws in your project. Like the structure and how and when you are calling things. You need to modularise it out, create methods for particular tasks and call those methods, rather than have a great lump of code in oncreate.
I am sure you will have many questions about this. But currently this question is addressing your null pointer exception and that is all I will discuss here. For questions about this not relating to this exception, please ask a new question. Hope this helps.

Application stops working on mobile device but runs on emmulator

i have developed an app for 'bank simulation' which uses sqlite to create databases...
when i run the app on my mobile it stops unexpectedly....do i need to install any server to run sqlite based apps on mobile?

How to retrieve data from database in android Creating database on SqliteBrowser

I have jokes.db database. This database file imported from using this article., http://www.reigndesign.com/blog/using-your-own-sqlite-database-in-android-applications/. Now i have Jokes.db in to /data/data/a.b.c/database/Jokes.db. In this database , I have two table NepaliJokes and EnglishJokes. So Now I want to retrive this nepali and english jokes and display in to textview, But I have done following code but couldnot more idea behind How to retrieve data from database.
public class FunnyJokes extends Activity implements View.OnClickListener {
private SQLiteDatabase database;
#Override
protected void onCreate(Bundle savedInstanceState) {
Button back;
super.onCreate(savedInstanceState);
setContentView(R.layout.displayjoks1);
back = (Button) findViewById(R.id.back_btn);
back.setOnClickListener(this);
DataBaseHelper helper = new DataBaseHelper(this);
database = helper.getWritableDatabase();
loadJokes();
}
private void loadJokes() {
//jok=new ArrayList<String>();
/*Cursor c = database.query("SELECT title,body" +
" FROM " + 'tableName'
+ " WHERE category=1;",
null);*/
Cursor c = database.query("NepaliJokes",
null, null, null, null, null, null);
c.moveToPosition(0);
TextView tv= (TextView) findViewById(R.id.textView1);
tv.append(c.getString(1));
c.close();
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.back_btn:
FunnyJokes.this.finish();
break;
default:
break;
}
}
}
I also use the database file import from in DDMS->fileExploer. I import database file Pull mobile icon from left of file explorer section.

To read values from the table:
Create a cursor to read data from the database.
Write the following function.
public Cursor retrieveRecords(int category)
{
Cursor c = null;
c = db.rawQuery("select title,body from tablename where category=" +category, null);
return c;
}
Now get the values from the cursor.
public void getDataFromDatabase()
{
try
{
Cursor cursor = null;
db.OpenDatabase();
cursor = db.retrieveRecords();
if (cursor.getCount() != 0)
{
if (cursor.moveToFirst())
{
do
{
titleArrayList.add(cursor.getString(cursor.getColumnIndex("title")));
bodyArrayList.add(cursor.getString(cursor.getColumnIndex("body")));
} while (cursor.moveToNext());
}
db.closeDatabase();
}
cursor.close();
}
catch(Exception e)
{
e.printStackTrace();
}
}

I have two table and apply all the query insert update delete and createtable select using the code it is working fine.
I hope this is help.

First of all don't use tv.append instead use setText because if u use append then ur next joke will be append to the previous one and textView show the jokes as you click the button
Actually the answere is long enough so
I have written a ansere in my blog please see the link the code will do exactly what you are lokking for but i just made one table you can add more table similarly.
