Android: Unable To Insert Data Into Sqlite Using Dbhelper And Contract Class

public class Main2Activity extends AppCompatActivity { private EditText editText1, editText2, editText3, editText4; private Button button; @Override protected void

Solution 1:

Replace your CREATE_TABLE query with:

StringCREATE_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
