hi i wanted to create a database for my app in android studio but only the constructor of my SQLiteOpenHelper extended class is called in the activity i thought it was my problem but when i copy/paste the code in eclipse it worked perfectlyyyyy!!!!! and the on create method was called here is my SQLiteOpenHelper class:
public class TestHelper extends SQLiteOpenHelper {
private static final String DATABASE_NAMEt = "testdatabase";
private static final int DATABASE_VERSION = 2;
private static final String TABLE_NAME = "SANATABLE";
private static final String UID="_id";
private static final String NAME="Name";
private static final String ADDRESS="Address";
private static final String CREATE_TABLE="CREATE TABLE "+TABLE_NAME+" ("+UID+" INTEGER PRIMARY KEY AUTOINCREMENT, "+NAME+" VARCHAR(255), "
+ ADDRESS+" VARCHAR(255));";
private static final String DROP_TABLE="DROP TABLE"+TABLE_NAME+" IF EXISTS;";
private Context context;
public TestHelper(Context context) {
super(context, DATABASE_NAMEt, null, DATABASE_VERSION);
this.context=context;
messageBD.messageBD(context, "constructor called");
}
public void onCreate(SQLiteDatabase db) {
try {
db.execSQL(CREATE_TABLE);
messageBD.messageBD(context, "on create called");
Log.d("SANA", "on create called");
} catch (android.database.SQLException e) {
messageBD.messageBD(context,""+e);
Log.d("SANA", "error is" + e);
}
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
try {
db.execSQL(DROP_TABLE);
onCreate(db);
messageBD.messageBD(context, "on upgrade called");
} catch (android.database.SQLException e) {
messageBD.messageBD(context,""+e);
}
}
}
the class messagebd contains only a toast to test things and my main activity got hello world statement only here it is:
public class TestBDactivity extends Activity {
TestHelper testHelper ;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_bdactivity);
testHelper=new TestHelper(this);
SQLiteDatabase sqLiteDatabase= testHelper.getWritableDatabase();
}
}
and finally my logcat when i work with ANDROID STUDIO 1.0.1
