Android : sqlcipher - net.sqlcipher.database.SQLiteException: not an error

I'm using sqlcipher for encoding my database . I've added the libraries and jar files and it works fine on api 18 and 16 but It gives me this error on api 11 :

 java.lang.RuntimeException: Unable to start activity ComponentInfo{}: net.sqlcipher.database.SQLiteException: not an error

this is how I open database from sd card :

SQLiteDatabase.loadLibs(context);
String outFileName = Environment.getExternalStorageDirectory() +"/Android/data/"+ context.getPackageName()
                + "/files/files.dll";
        File databaseFile = new File(outFileName);
        db = SQLiteDatabase.openOrCreateDatabase(databaseFile,"mypass", null);

this is the image of my asset folder and lib folder :

Could you help me to solve this ?

thanks
