public final static String DATABASE_NAME = "contacts.db";

public DbHelper(Context context) {

#Override
public void onCreate(SQLiteDatabase db) {
String CREATE_TABLE = "CREATE TABLE " + Entry.TABLE_NAME + " ("
+ Entry._ID + " TEXT PRIMARY KEY AUTOINCREMENT, "
+ Entry.C_UNAME + " TEXT, "
+ Entry.C_PASS + " TEXT, "
+ Entry.C_CPASS + " TEXT, "
+ Entry.C_PNO + " TEXT" + ")";
db.execSQL(CREATE_TABLE);
}
#Override

}
There are no syntax errors but still, the app is crashing.
Replace your CREATE_TABLE query with:
String CREATE_TABLE = "CREATE TABLE " + Entry.TABLE_NAME + " ("
+ Entry._ID + " INTEGER PRIMARY KEY AUTOINCREMENT, "
+ Entry.C_UNAME + " TEXT, "
+ Entry.C_PASS + " TEXT, "
+ Entry.C_CPASS + " TEXT, "
+ Entry.C_PNO + " TEXT" + ")";
You can't have a TEXT type have an AUTOINCREMENT property as you currently have it on your _ID field. You need to change it to be an INTEGER so it can be used as PRIMARY KEY and then have it AUTOINCREMENT

When I was releasing an apk on google play I had to use a different package name cause of "com.example". I tried this and I get crash after testing an application. Before that everything was ok. I can send a manifest.

You are trying to get 0 index in the database. Every time you add a new Note its ID will be 0. So, change your database KEY_ID to AUTOINCREMENT.
String query = "CREATE TABLE " + DATABASE_TABLE + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," +
KEY_TITLE + " TEXT," +
KEY_CONTENT + " TEXT," +
KEY_DATE + " TEXT," +
KEY_TIME + " TEXT," +
KEY_PIES + " TEXT," +
KEY_RASAPSA + " TEXT," +
KEY_TEL + " TEXT," +
KEY_ZDJECIE + " TEXT" + ")";
db.execSQL(query);
Then check your cursor not null in
getNote()
I'm creating an SQLiteDatabase, I was able to add all the EditText values into the Database however when trying to add a Date which I have used a DatePicker to find and input into TextView, the app crashes.
Is there a different way to insert TextView values into SQLiteDatabase.
Main Activity:
public class MainActivity extends AppCompatActivity implements DatePickerDialog.OnDateSetListener {
DatabaseHelper peopleDB;
TextView etDate;
Button btnAddData, btnViewData;
EditText etName, etEmail, etAddress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
peopleDB = new DatabaseHelper(this);

etDate = (TextView) findViewById(R.id.textView4);
btnAddData = (Button) findViewById(R.id.btnAddData);
btnViewData = (Button) findViewById(R.id.btnViewData);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
DialogFragment datePicker = new DatePickerFragment();
datePicker.show(getSupportFragmentManager(), "date picker");
}
});
AddData();
ViewData();
}
public void AddData() {
btnAddData.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
String name = etName.getText().toString();
String email = etEmail.getText().toString();
String tvShow = etAddress.getText().toString();
String date = etDate.getText().toString();
boolean insertData = peopleDB.addData(name, email, tvShow, date);
if (insertData == true) {
Toast.makeText(MainActivity.this, "Data Successfully Inserted!", Toast.LENGTH_LONG).show();
} else {
Toast.makeText(MainActivity.this, "Something went wrong :(.", Toast.LENGTH_LONG).show();
}
}
});
}
#Override

c.set(Calendar.YEAR, year);
c.set(Calendar.MONTH, month);
c.set(Calendar.DAY_OF_MONTH, dayOfMonth);
String currentDateString = DateFormat.getDateInstance(DateFormat.FULL).format(c.getTime());
TextView textView = (TextView) findViewById(R.id.textView4);
textView.setText(currentDateString);
}
public void ViewData() {
btnViewData.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {

if(data.getCount() == 0) {

//display message

I think that you did not add date column in create database statement so change this at DatabaseHelper class
#Override
public void onCreate(SQLiteDatabase db) {
String createTable = "CREATE TABLE " + TABLE_NAME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
" NAME TEXT, EMAIL TEXT, ADDRESS TEXT)";
db.execSQL(createTable);
}
to
#Override
public void onCreate(SQLiteDatabase db) {
String createTable = "CREATE TABLE " + TABLE_NAME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT, " +
" NAME TEXT, EMAIL TEXT, ADDRESS TEXT , DATE DATETIME)";
db.execSQL(createTable);
}
For best code refactor variables names by click shift+F6 then rename
public static final String COL1 = "ID";
public static final String COL2 = "NAME";
public static final String COL3 = "EMAIL";
public static final String COL4 = "ADDRESS";
public static final String COL5 = "DATE";
to
public static final String COL_ID = "ID";
public static final String COL_NAME = "NAME";
public static final String COL_EMAIL = "EMAIL";
public static final String COL_ADDRESS = "ADDRESS";
public static final String COL_DATE = "DATE";
and change create statement to
#Override
public void onCreate(SQLiteDatabase db) {
String createTable = "CREATE TABLE " + TABLE_NAME + " (" +
COL_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
COL_NAME +" TEXT," +
COL_EMAIL +" TEXT,"+
COL_ADDRESS + " TEXT ,"+
COL_DATE + " DATETIME)";
db.execSQL(createTable);
}

Could you check the context received by DataBaseHelper constructor. May be it has NULL value.
Try this,
databaseHelper = new DatabaseHelper(getActivity());
For Second issue, You need to revisit to your table structure or query construction. Error log said there is no column named as "NAME" in table which is your querying table. Please check once again the basics.

I have a problem like this:
I have registration form for new customer but then he filled out all fields like login, password and so on. Nothing happened in Base SQL.
I don`t understand my mistake here.
switch (v.getId()) {
case R.id.create_account:
database = dbHelper.getWritableDatabase();
contentValues = new ContentValues();
// AlertDialog Registration
View viewInflated = LayoutInflater.from(this).inflate(R.layout.registration_form, (ViewGroup) findViewById(android.R.id.content), false);
inputPassword = (EditText) viewInflated.findViewById(R.id.input_password);
inputLogin = (EditText) viewInflated.findViewById(R.id.input_login);
inputEmail = (EditText) viewInflated.findViewById(R.id.input_email);
builder.setView(viewInflated);
builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
String login = inputLogin.getText().toString();
String email = inputEmail.getText().toString();
String password = inputPassword.getText().toString();
// Передаем с помошью КонтентВелью наши значения из полей
contentValues.put(DBHelper.KEY_NAME, login);
contentValues.put(DBHelper.KEY_EMAIL, email);
contentValues.put(DBHelper.KEY_PASSWORD, password);
// Записываем в базу ТейблКонтакты
database.insert(DBHelper.TABLE_CONTACTS, null, contentValues);
database.close();
Toast toast = Toast.makeText(getApplicationContext(), "Вы зарегистрированы", Toast.LENGTH_LONG);
toast.show();
dialog.cancel();
}
});
And my DBHelper
public class DBHelper extends SQLiteOpenHelper {
public static final int DATABASE_VERSION = 1;
public static final String DATABASE_NAME = "contactDb";
public static final String TABLE_CONTACTS = "contacts";
public static final String KEY_ID = "_id";
public static final String KEY_NAME = "name";
public static final String KEY_PASSWORD = "password";
public static final String KEY_EMAIL = "email";
public DBHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table " + TABLE_CONTACTS + "(" + KEY_ID + " integer primary key," + KEY_NAME + " text," + KEY_PASSWORD + " text" + KEY_EMAIL + " text" + ")");
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("drop table if exists " + TABLE_CONTACTS);
onCreate(db);
}
}
