    <p>I did the notepad tutorials and my SQL server is a modified version of that. For some reason my app is not writing to it correctly. Any help would be greatly appreciated. I dont understand what part of the code is wrong.</p> <pre><code> package com.drawing; import android.content.ContentValues; import android.content.Context; import android.database.Cursor; import android.database.SQLException; import android.database.sqlite.SQLiteDatabase; import android.database.sqlite.SQLiteOpenHelper; import android.util.Log; public class NotesDbAdapter { public static final String KEY_ROWID = "_id"; public static final String KEY_X = "x"; public static final String KEY_Y = "y"; public static final String KEY_Size = "size"; private static final String TAG = "NotesDbAdapter"; private DatabaseHelper mDbHelper; private SQLiteDatabase mDb; private static final String DATABASE_NAME = "data"; private static final String DATABASE_TABLE = "notes"; private static final int DATABASE_VERSION = 2; private static final String DATABASE_CREATE = " create table " + DATABASE_TABLE + " (" + KEY_ROWID + " integer primary key autoincrement, " + KEY_X + " text not null, " + KEY_Y + " text not null, " + KEY_Size + " text not null);"; private final Context mCtx; 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 (Exception e) { Log.e("dbAdapter", e.getMessage().toString()); } } @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 notes"); onCreate(db); } } public NotesDbAdapter(Context ctx) { this.mCtx = ctx; } public NotesDbAdapter open() throws SQLException { mDbHelper = new DatabaseHelper(mCtx); mDb = mDbHelper.getWritableDatabase(); return this; } public void close() { mDbHelper.close(); } public long createNote(float f, float g, int size) { ContentValues initialValues = new ContentValues(); initialValues.put(KEY_X, f); initialValues.put(KEY_Y, g); initialValues.put(KEY_Size, size); return mDb.insert(DATABASE_TABLE, null, initialValues); } public boolean deleteNote(long rowId) { return mDb.delete(DATABASE_TABLE, KEY_ROWID + "=" + rowId, null) &gt; 0; } public Cursor fetchAllNotes() { return mDb.query(DATABASE_TABLE, new String[] {KEY_ROWID, KEY_X,KEY_Y,KEY_Size}, null, null, null, null, null); } public Cursor fetchNote(long rowId) throws SQLException { Cursor mCursor = mDb.query(true, DATABASE_TABLE, new String[] {KEY_ROWID, KEY_X,KEY_Y,KEY_Size}, KEY_ROWID + "=" + rowId, null, null, null, null, null); if (mCursor != null) { mCursor.moveToFirst(); } return mCursor; } public boolean updateNote(long rowId, int x, int y, int size) { ContentValues args = new ContentValues(); args.put(KEY_X, x); args.put(KEY_Y, y); args.put(KEY_Size, size); return mDb.update(DATABASE_TABLE, args, KEY_ROWID + "=" + rowId, null) &gt; 0; } } </code></pre>

    3. COIs it possible to see the INSERT generated for that? Are you certain the table is created? Does any of the other calls - ie. SELECT work?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
