Hi All,
I am a not experienced developer. All I want to do is make a small app to track information of football on TV. I want to do it through a small DB however I've been struggling a lot with an error I've been trying to discover in the last two weeks but I have not been able.
I have teh following code in the class I create the DB
public class DBAdapter {
public static final String KEY_ROWID = "_id";
public static final String KEY_GDATE = "gdate";
public static final String KEY_GTIME = "gtime";
public static final String KEY_GGAME = "ggame";
public static final String KEY_GCOMPETITION = "gcompetition";
public static final String KEY_GCHANNEL = "gchannel";
private static final String TAG = "DBAdapter";
private static final String DATABASE_NAME = "FonTV";
private static final String DATABASE_TABLE = "games";
private static final int DATABASE_VERSION = 2;
private static final String DATABASE_CREATE =
"create table games (_id integer primary key autoincrement, "
+ "gdate text not null, gtime text not null, ggame text not null" +
"gcompetition text not null, gchannel text not null);";
private final Context context;
private DatabaseHelper DBHelper;
private SQLiteDatabase db;
public DBAdapter(Context ctx)
{
this.context = ctx;
DBHelper = new DatabaseHelper(context);
}
private static class DatabaseHelper extends SQLiteOpenHelper
{
DatabaseHelper(Context context)
{
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}
@Override
public void onCreate(SQLiteDatabase db)
{
try {
db.execSQL(DATABASE_CREATE);
} catch (SQLException e) {
e.printStackTrace();
}
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
{
Log.w(TAG, "Upgrading database from version " + oldVersion + " to "
+ newVersion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS contacts");
onCreate(db);
}
}
//---opens the database---
public DBAdapter open() throws SQLException
{
db = DBHelper.getWritableDatabase();
return this;
}
//---closes the database---
public void close()
{
DBHelper.close();
}
//---insert a contact into the database---
public long insertContact(String gdate, String gtime, String ggame, String gcompetition, String gchannel )
{
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_GDATE, gdate);
initialValues.put(KEY_GTIME, gtime);
initialValues.put(KEY_GGAME, ggame);
initialValues.put(KEY_GCOMPETITION, gcompetition);
initialValues.put(KEY_GCHANNEL, gchannel);
return db.insert(DATABASE_TABLE, null, initialValues);
}
}
And the main class where I try to insert data has this:
public class ResultsDBActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
DBAdapter db = new DBAdapter(this);
db.open();
long id = db.insertContact("12/may", "08:00", "Leeds vs York", "JUME Cup", "ITV, BBC");
id = db.insertContact("13/may", "09:00", "London vs Bath", "JUME Cup", "ITV, BBC2");
db.close();
}
}
However when I try to run it, the debugger shows and error that says:
E/Database(330): android.database.sqlite.SQLiteException: no such table: games: , while compiling: INSERT INTO games(gchannel, ggame, gtime, gdate, gcompetition) VALUES(?, ?, ?, ?, ?);
I’ve trying to change parameters and many things but I haven’t found where the problem is. Can someone help me please?

Hello
I'm new to programming and I'm trying to make a java application that will "hear" (not record necessarily) the sound and display how loud is.I'm thinking of converting the sound recordings to numbers,so I can see the difference on the sound levels.I got this code and I added the "getLevel()" method,which returns the amplitude of the current recording,but it's returning -1 everytime.I guess I'm not using it properly. Any ideas how I must call this method?I have to deliver my project in a week,so any help will be much appreciated!
Code:
public class Capture extends JFrame {
protected boolean running;
ByteArrayOutputStream out;
public Capture() {
super("Capture Sound Demo");

Ok,I managed to make it capture audio and print on a xls file the timestamp and the value of the current sample,but there is a problem : even I've put some spaces between the time and the value and it seems that they are in different columns,they are actualy on the same column of the xls,it's just expanded and covers the next column (I can put a print screen if you don't understand).How can I make it print the data of time and amplitude in two different columns?Here's my code of the class which creates the file and saves the data on xls :
Code:
package soundRecording;
import java.io.File;
import java.util.Formatter;
public class Save {
static Formatter y;
public static void createFile() {
Date thedate = new Date();
final String folder = thedate.curDate();
final String fileName = thedate.curTime();
try {
String name = "Time_"+fileName+".csv";
y = new Formatter(name);
File nof = new File(name);
nof.createNewFile();
System.out.println("A new file was created.");
}
catch(Exception e) {
System.out.println("There was an error.");
}
}
public void addValues(byte audio) {
Date d = new Date();
y.format("%s " + " %s%n",d.curTime(), audio);
}
public void closeFile() {
y.close();
}
}

Hi, thank you for using XDA assist.
There is a general forum for android here http://forum.xda-developers.com/android/help where you can get better help and support if you try to ask over there.
Good luck.

My MainActivity has a RecyclerView adapter, and data to this RecyclerView is added through a AlertDialog which passes the entered text to the MainActivity. The recycler view gets refreshed somehow when the positive button in the dialog is pressed even though I never call notifyItemInserted() or notifyDatasetChange() after passing the new input. I want to know how this happens, my guess is the recyclerview is somehow refreshed after the positive button is pressed in the dialog box.
Custom AlertDialog Code:
Code:
public class CustomDialog extends AppCompatDialogFragment {
OnNoteAddedListener onNoteAddedListener;
public interface OnNoteAddedListener {
public void onClick(String note);
}
public CustomDialog(OnNoteAddedListener onNoteAddedListener) {
this.onNoteAddedListener = onNoteAddedListener;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
// Get the layout inflater
final LayoutInflater inflater = getActivity().getLayoutInflater();
final View dialogLayout = inflater.inflate(R.layout.dialog_box, null);
// Inflate and set the layout for the dialog
// Pass null as the parent view because its going in the dialog layout
builder.setView(dialogLayout).setPositiveButton("Ok", new DialogInterface.OnClickListener() {@Override
public void onClick(DialogInterface dialog, int id) {
EditText addNote = dialogLayout.findViewById(R.id.note_text);
String note = addNote.getText().toString();
onNoteAddedListener.onClick(note);
}
}).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
CustomDialog.this.getDialog().cancel();
}
});
return builder.create();
}
}
Adapter code:
