我已经设置了服务器，目前停留在我的 android 代码中。
谁能帮我分享一下灯？
这是databasehandler我的课android application。

我使用 android studio 发现的错误是

sdb.execSQL("DROP TABLE IF EXIST " + DataTabel.TableInfo.NAMA_TABEL_VERSI_TUGAS);
sdb.execSQL("DROP TABLE IF EXIST " + DataTabel.TableInfo.NAMA_TABEL_ATASAN_BAWAHAN);
这么说UNREACABLE STATEMENT。
