android连接mysql数据库8.0的DBhelper怎么写

你好，关于连接MySQL数据库8.0的DBhelper，可以参考以下代码：

public class DBHelper extends SQLiteOpenHelper {
    private static final String DATABASE_NAME = "db";
    private static final int DATABASE_VERSION = 1;
    private static final String TABLE_NAME = "table_name";

    private static final String COLUMN_ID = "id";
    private static final String COLUMN_NAME = "name";
    private static final String COLUMN_PHONE = "phone";

    private static final String CREATE_TABLE = "CREATE TABLE " + TABLE_NAME + " (" +
            COLUMN_ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
            COLUMN_NAME + " VARCHAR, " +
            COLUMN_PHONE + " VARCHAR" +
            ")";

    public DBHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(CREATE_TABLE);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

    }
}

此代码是一个DBhelper的实例，在连接MySQL数据库8.0的时候需要进行一些特殊的处理，具体可以参考相关的文档或者查询相关资料。
