Android Library中關於SQLCipher的問題

這是我的程序。Android Library中關於SQLCipher的問題

public class MainActivity extends Activity { 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 

     setContentView(R.layout.activity_main); 

     InitializeSQLCipher(); 
    } 



     private void InitializeSQLCipher() { 
       SQLiteDatabase.loadLibs(this); 

       File databaseFile = getDatabasePath("demo.db"); 

       databaseFile.mkdirs(); 

       databaseFile.delete(); 

       SQLiteDatabase database = SQLiteDatabase.openOrCreateDatabase(databaseFile, "test123", null); 


       database.execSQL("create table t1(a, b)"); 

       database.execSQL("insert into t1(a, b) values(?, ?)", new Object[]{"one for the money", 
                       "two for the show"}); 
     } 
}

我有添加一些三個庫在這個方案，這是在這個環節........ https://github.com/sqlcipher/android-database-sqlcipher

現在我的查詢是我收到以下錯誤。如何克服以獲得完美的解決方案...
