在調用getReadableDatabase時獲取SQLiteException

-1

上面的代碼是intent服務的一部分，我正在訪問實際上是DBHelper類的GinisTable類。在調用getReadableDatabase時獲取SQLiteException

protected void onHandleIntent(Intent intent) { 
     if (intent != null) { 
      DeviceInfoTable deviceInfoTable = new DeviceInfoTable(UploadGiniData.this); 
      DeviceInfo deviceInfo = deviceInfoTable.getDeviceInfo(); 

      String generatedDeviceInfo = deviceInfo.getGeneratedDeviceId(); 

      GinisTable ginisTable = new GinisTable(UploadGiniData.this); 
      List<GiniInfo> giniInfoList = ginisTable.getGiniInfoList(); 
}

我GinisTable類是如下：

'getReadableDatabase（）'不返回空值。出錯時拋出異常。你是否用一個存根'return null'版本自己重寫了這個方法？ – laalto

不，我沒有重寫該方法。 –

也發佈你的堆棧跟蹤。 – laalto

將同一個數據庫文件中的所有表放到同一個sqlite助手中。幫助器用於版本控制數據庫文件，而不是表格

是的，這就是我在問題的評論中寫的。很好，你解決了問題。但是，問題本身並不包含告訴問題所在的必要信息。投票結束，解決對別人沒有幫助。 – laalto

替換此

SQLiteDatabase db = this.getReadableDatabase();

通過這樣的：

SQLiteDatabase db = GinisTable.this.getReadableDatabase();

如果工作請標明正確

根本不工作 –

嘗試關閉創建一個新的連接之前，現有的數據庫連接。

public int insertGini(GiniInfo giniInfo) { 

    SQLiteDatabase db = this.getWritableDatabase(); 
    // ............... 
    int giniID = (int) db.insert(GinisTable.TABLE_GINI, null, contentValues); 
    db.close(); //Close the database connection. 
    return giniID; 
}

在某些設備中，此連接阻止創建新連接。

無法正常工作。已經試過這個 –

getReadableDatabase（）永遠不會返回null，請發佈你的logcat，以便我們可以更好地幫助你。 – Kartheek

NullPointerException不是因爲getReadableDatabase（），而是因爲數據庫中不存在表。創建表後，表名更改時可能會發生此錯誤，一旦卸載應用程序，然後再次安裝， – Kartheek

我有完全相同的問題。

SQLiteOpenHelper的構造函數不調用OnCreate中，這條線之後：

super(context, Config.DB_NAME, null, 1);

你必須添加一行要麼getWritableDatabase（）或getReadableDatabase（），它會調用的onCreate如果不存在。

完成它但不工作 –

什麼是Config.DB_NAME？項目中是否有另一個電話？

super(context, Config.DB_NAME, null, 1);

如果是這樣的話，數據庫被創建，所以該類中的onCreate將不會被調用，因此該表不存在。

解決方法是將所有表放在一起派生的SQLiteOpenHelper類。

1.也許在設備上的舊數據庫版本。完全從設備上刪除應用程序，並更改版本號super(context, DB_NAME, null, 2);末兩位數

2.檢查補丁與SDK版本兼容

if(android.os.Build.VERSION.SDK_INT >= 4.2){ 
    DB_PATH = context.getApplicationInfo().dataDir + "/databases/"; 
} else { 
    DB_PATH = "/data/data/" + context.getPackageName() + "/databases/"; 
}

到文件連接到數據庫之前設置錯了語言環境。 Like Locale.setDefault(Settings.ACTION_LOCALE_SETTINGS);

4.也許數據庫文件已被打開。
