Question

上面的代码是意向服务的一部分，我正在访问GinisTable类，它实际上是一个DBHelper类。

 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();
}

我的GinisTable类如下：

Answer 1

替换此

 SQLiteDatabase db = this.getReadableDatabase();

由此：

 SQLiteDatabase db = GinisTable.this.getReadableDatabase();

如果工作请标记正确的

Answer 2

尝试在创建新连接之前关闭现有的数据库连接。

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;
}

在某些设备中，此连接会阻止创建新连接。

Answer 3

我遇到了完全相同的问题。

SQLiteOpenHelper的构造函数不会调用OnCreate。在此行之后：

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

你必须添加一行getWritableDatabase（）或getReadableDatabase（），如果不存在，将调用onCreate。

Answer 4

将同一数据库文件中的所有表放入同一个sqlite帮助器中。帮助程序用于版本化数据库文件，而不是表

Answer 5

什么是Config.DB_NAME？在项目的其他地方还有另一个电话吗？

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

如果是这种情况，则创建数据库，以便不会调用此类中的onCreate，因此该表不存在。

解决方案是将所有表放在SQLiteOpenHelper的一个派生类中。

Answer 6

1。也许在设备上有旧的数据库版本。从设备中完全删除应用并更改版本号super(context, DB_NAME, null, 2);最后一位数

2. 检查与SDK版兼容的文件补丁

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

3. 在连接到DataBase之前，设置了错误的语言环境。与Locale.setDefault(Settings.ACTION_LOCALE_SETTINGS);

一样

4. 或许以前打开过数据库文件。

调用getReadableDatabase时获取SQLiteException
