本人尝试这在android中这样写，可是连接出错，求正确的写法

try
{
    File databaseFile = LauncherActivity.this.getDatabasePath("test.sqlite");
    if (!databaseFile.exists() && !databaseFile.createNewFile())
        Log.e(TAG, "nCreate: " + "创建数据库失败: " + databaseFile.getAbsolutePath());

    SimpleDataSource simpleDataSource = new SimpleDataSource();
    simpleDataSource.setJdbcUrl("jdbc:sqldroid:" + databaseFile.getAbsolutePath());
    simpleDataSource.setDriverClassName("org.sqldroid.SqldroidDriver");

    Dao dao = new NutDao(simpleDataSource);
    dao.create(AppEnvApplicationInfo.class, true);
}
catch (Exception e)
{
    Log.e(TAG, "onCreate: " + e.getLocalizedMessage(), e);
}
