Aber ich glaube, ich eingegeben haben die " Gemeinde "in jedem Teil. Dies ist der Code der db:

@Override 
public void onCreate(SQLiteDatabase database) { 

    String query = "CREATE TABLE geophysics_table (id_grid INTEGER PRIMARY KEY, site TEXT, " + 
      "n_tab TEXT, municipality TEXT, ctr TEXT, igm TEXT, coordinates TEXT, ref_geo_map TEXT, description_site TEXT, soil_type TEXT, culture_type TEXT, survey_method TEXT, instrument_type TEXT, resolution_survey TEXT, area_investigated TEXT, acquisition_method TEXT, frequency_feeler TEXT, range TEXT, max_depth TEXT, software TEXT, author TEXT, assistants TEXT, start_date TEXT, finish_date TEXT)"; 

Answer 1

Wahrscheinlich müssen Sie Ihre Datenbankversion erhöhen.

Nach Erhöhung wird onUpgrade Methode aufgerufen.

So können Sie alle Ihre Tabellen hier fallen lassen und onCreate anrufen.

Beispiel

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
    db.execSQL("DROP TABLE IF EXISTS firstTable"); 
    db.execSQL("DROP TABLE IF EXISTS secondTable"); 
    db.execSQL("DROP TABLE IF EXISTS thirdTable"); 
    onCreate(db); 
}
