Мой проект приложения словаря использует SQLite для хранения данных.Я получаю UNIQUE constraint failed: type.ps в методе createTablesAndProcess() при запуске приложения.

метод createTablesAndPorcess: 

public final void createTablesAndProcess() {
    boolean z = true;
    try {
        if (!doesExistsTable("other_words")) {
            this.wdb.execSQL("create table if not exists other_words(word TEXT PRIMARY KEY)");
            this.wdb.execSQL("INSERT INTO other_words ( word ) SELECT DISTINCT w FROM ( SELECT ot AS w FROM oten UNION SELECT word AS w FROM other )");
        }
    } catch (Exception e) {
        try {
            e.printStackTrace();
            z = false;
        } catch (Exception e2) {
            e2.printStackTrace();
            return;
        }
    }
    try {
        if (!doesExistsTable("new_study_plan")) {
            this.wdb.execSQL("create table if not exists new_study_plan(serial INTEGER PRIMARY KEY , word TEXT , add_time INTEGER NOT NULL)");
        }
    } catch (Exception unused) {
    }
    try {
        if (!doesExistsTable("new_study_plan_other")) {
            this.wdb.execSQL("create table if not exists new_study_plan_other(serial INTEGER PRIMARY KEY , word TEXT , add_time INTEGER NOT NULL)");
        }
    } catch (Exception unused2) {
    }
    try {
        if (!doesExistsTable("new_added")) {
            this.wdb.execSQL("create table if not exists new_added(word TEXT PRIMARY KEY , details TEXT  NOT NULL)");
        }
    } catch (Exception unused3) {
    }
    try {
        if (!doesExistsTable("new_history")) {
            this.wdb.execSQL("create table if not exists new_history(serial INTEGER PRIMARY KEY , word TEXT , add_time INTEGER NOT NULL)");
        }
    } catch (Exception unused4) {
    }
    if (!doesExistsTable("new_history_other")) {
        this.wdb.execSQL("create table if not exists new_history_other(serial INTEGER PRIMARY KEY , word TEXT , add_time INTEGER NOT NULL)");
    }

//Crash on the below line.
    this.wdb.execSQL("INSERT INTO type VALUES ( NULL,'MORE')");
    if (z) {
        manageInThread();
    }
}

задача initializeDatabase: 

private void initilizeDatabase(final int i, final boolean z) {
    new AsyncTask<String, String, String>() {
        protected void onPreExecute() {
            try {
                if (i == Constants.DB_VERSION) {
                    DictionaryActivity.this.progressMessageView.setVisibility(8);
                } else {
                    DictionaryActivity.this.progressMessageView.setVisibility(0);
                }
            } catch (Exception e) {
                LogUtils.log(DictionaryActivity.this, e);
            }
        }

        protected String doInBackground(String... strArr) {

                DictionaryActivity.this.databaseAccessor.restoreFile(DictionaryActivity.this, DictionaryActivity.this.getDatabasePath(Constants.BACKUP_FILE_NAME));
            }
            return null;

                Utils.createShortCut(DictionaryActivity.this, DictionaryActivity.class);
                Utils.manageClipboardAndNotificationbar(DictionaryActivity.this);
                try {

                    Intent intent = new Intent();
                    intent.setAction("android.speech.tts.engine.CHECK_TTS_DATA");
                    DictionaryActivity.this.startActivityForResult(intent, DictionaryActivity.CHECK_TTS);
                } catch (Exception e) {

                DictionaryActivity.this.showHideOCR(true);
                DictionaryActivity.this.showOverlayPermissionPopupIfRequired();
            } catch (Exception e2) {
                if (!(e2 instanceof ActivityNotFoundException)) {
                    LogUtils.log(DictionaryActivity.this, e2);
                }
            }
            DictionaryActivity.this.isExitingOk = true;
            if (DictionaryActivity.this.IDSToPS.size() == 0) {
                DictionaryActivity.this.resetDatabase();
            }
        }
    }.execute();
}

Ошибка возникает при вызове createTablesAndProcess в методе инициализации и в строке this.wdb.execSQL("INSERT INTO type VALUES ( NULL,'MORE')");.Дайте мне знать в комментариях, если вы хотите больше журналов.

Это простая ошибка. Каждый элемент столбца ps в таблице type должен быть уникальным, поскольку вы создали таблицу таким образом. Но во время выполнения оператора INSERT INTO type VALUES ( NULL,'MORE') он каким-то образом имеет то же значение (если это первый столбец, затем NULL) в столбце ps уже.
