在Android 2.3.3中使用sqlcipher時。我收到錯誤。在Android中使用sqlcipher後獲取「sqlite3_open_v2（」mydatabase.db「，＆句柄，6，NULL）失敗」
這裏是我DB.java類
import android.content.ContentValues;
import android.content.Context;
import android.database.Cursor;
import android.util.Log;
import net.sqlcipher.database.SQLiteDatabase;
import net.sqlcipher.database.SQLiteDatabase.CursorFactory;
import net.sqlcipher.database.SQLiteOpenHelper;
public class DB {
private static String _DB_NAME = "mydatabase.db";
private static int _DB_VERSION = 1;
private Context _context;
private DBHelper _helper;
public DB(Context context) {
SQLiteDatabase.loadLibs(context);
this._context = context;
this._helper = new DBHelper(this._context, _DB_NAME, null, _DB_VERSION);
SQLiteDatabase sqdb = this._helper.getWritableDatabase("123");
sqdb.close();
}
public void insertValuesInTable() {
try {
SQLiteDatabase sqdb = SQLiteDatabase.openOrCreateDatabase(_DB_NAME, "123",null);
sqdb.execSQL("insert into mytable(category, total) values (1,"100");");
sqdb.close();
} catch (Exception e) {
e.printStackTrace();
}
}
private static class DBHelper extends SQLiteOpenHelper {
public DBHelper(Context context, String name, CursorFactory factory,
int version) {
super(context, name, factory, version);
}
@Override
public void onCreate(SQLiteDatabase db) {
createTables(db);
}
@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
private void createTables(SQLiteDatabase db) {
try {
String query1;
query1 = "Create table if not exists mytable (category integer primary key, total text) ; ";
db.execSQL(query1);
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
創建DB.java的對象，並利用它這樣
DB _db = new DB(getApplicationContext());
_db.insertValuesInTable();
當我執行這一行_db.insertValuesInTable();我得到這個錯誤
sqlite returned: error code = 14, msg = cannot open file at line 32288 of [6d326d44fd]
sqlite returned: error code = 14, msg = os_unix.c:32288: (2) open(//mydatabase.db) -

我已經適當地包括所有.so，.jar & .zip文件。我仍然得到這個錯誤。如何解決這個問題？
