Question

When I use the getPesoCount() like in the:

Log.v("SQL", String.valueOf(getPesoCount()));

I get aN error:

FATAL EXCEPTION: main
java.lang.IllegalStateException: attemp to re-open an already-closed object: android.database.sqlite.SQLiteQuery(mSql = SELECT * FROM pesoTable)…

 public void addPeso(int peso, String date) {
        SQLiteDatabase db = this.getWritableDatabase();

        ContentValues values = new ContentValues();
        values.put(KEY_PESO, peso); // Contact Name
        values.put(KEY_DATE, date); // Contact Phone Number

        // Inserting Row
        db.insert(TABLE_PESO, null, values);
        Log.v("SQL", String.valueOf(getPesoCount()));
        db.close(); // Closing database connection

    }


    public int getPesoCount() {
        String countQuery = "SELECT  * FROM " + TABLE_PESO;
        SQLiteDatabase db = this.getReadableDatabase();
        Cursor cursor = db.rawQuery(countQuery, null);
        cursor.close();

        // return count
        return cursor.getCount();
    }

If I don’t use getPesoCount(), no error occurs.

Can someone help me?

attempt to re-open an already-closed object:

Exception tells you a lot!

If you want to use the cursor further do not call cursor.close(); call it when you are sure that you do not need it anymore.
