無法在Android AVD上運行我的項目

Question

我嘗試在android上測試數據庫。我想在sumsung GALAXY TAB中運行我的項目。 因此，我將AVD設置為Galaxy Nexus，RAM = 512，VM Heap = 64，SD卡= 1024 MiB。 我創建的android項目名稱為SQLiteDatabase。 當我在AVD上運行SQLiteDatabase時，顯示此錯誤。

不幸的是，SQLite數據庫已停止。

我不知道為什么我不能運行SQLiteDatabase項目，這是logcat的錯誤。

Answer 1

ComponentInfo{com.example.sqlitedatabase/com.example.sqlitedatabase.MainActivity}: android.database.sqlite.SQLiteException: near "tabletool": syntax error (code 1): , while compiling: create tabletool(idinteger primary key autoincrement ,nametext ,amountnumericunitunit 01-09 04:17:35.417: E/AndroidRuntime(6848): at 

沒有可用的代碼，但是基於上面的異常堆棧，看來您在創建表“ tabletool”中存在一些語法錯誤

確保創建表語法有效（空格，冒號等，在需要的地方）。

Answer 2

嘿，在日志中，我發現您的表查詢錯誤。

像這樣更改此查詢

create tabletool(id integer primary key autoincrement ,name text

我在日志中只能看到兩個忘記了保持空格的參數。 在參數和數據類型之間放置空格，然后嘗試一下。 它為您工作。

檢查您以idinteger和nametext編寫的查詢，該查詢應為id integer和name text
