如何將SQLcipher添加到android項目？

-1

我試圖使用SQLCipher加密我的數據庫爲我的project.ive添加了所有資產和libs需要使用sqlCipher，但問題是，我有一個專門用於數據庫操作的整個類，所以我有點困惑，要添加所提及的here所需的代碼。我曾嘗試在我的數據庫open()方法中初始化上述庫，但這只是給了我一個沒有這樣的表異常。如何將SQLcipher添加到android項目？

繼承我的代碼在任何修改之前。任何幫助感激地接受了

public class DataBaseHandler { 
public static final String KEY_ID = "id"; 
public static final String KEY_XCOD = "xcod"; 
public static final String KEY_YCOD = "ycod"; 
public static final String KEY_IMG = "img"; 
public static final String KEY_PATTERN = "pattern"; 
public static final String KEY_PACKAGENAME = "packagename"; 
private static final String DATABASE_NAME = "P3UserDb"; 
private static final String DATABASE_USERTABLE = "LoginDetailsTable"; 
private static final String DATABASE_PATTERNTABLE = "PatternDetailsTable"; 
private static final String DATABASE_LOCKEDAPPSTABLE = "LockedAppsTable"; 
private static final int DATABASE_VERSION = 1; 

private DbHelper ourHelper; 
private final Context ourContext; 
private SQLiteDatabase ourDatabase; 

public static class DbHelper extends SQLiteOpenHelper { 

    public DbHelper(Context context) { 
     super(context, DATABASE_NAME, null, DATABASE_VERSION); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     // TODO Auto-generated method stub 
     db.execSQL("CREATE TABLE " + DATABASE_USERTABLE + " (" + KEY_ID 
       + " INTEGER PRIMARY KEY AUTOINCREMENT, " + KEY_XCOD 
       + " INTEGER NOT NULL, " + KEY_YCOD + " INTEGER NOT NULL, " 
       + KEY_IMG + " TEXT NOT NULL);"); 
     db.execSQL("CREATE TABLE " + DATABASE_PATTERNTABLE + " (" 
       + KEY_PATTERN + " STRING NOT NULL);"); 
     db.execSQL("CREATE TABLE " + DATABASE_LOCKEDAPPSTABLE + " (" 
       + KEY_PACKAGENAME + " STRING);"); 
    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     // TODO Auto-generated method stub 
     db.execSQL("DROP TABLE IF EXISTS " + DATABASE_USERTABLE); 
     db.execSQL("DROP TABLE IF EXISTS " + DATABASE_PATTERNTABLE); 
     db.execSQL("DROP TABLE IF EXISTS " + DATABASE_LOCKEDAPPSTABLE); 
     onCreate(db); 
    } 
} 

public DataBaseHandler(Context c) { 
    ourContext = c; 
} 

public DataBaseHandler open() throws SQLException { 
    ourHelper = new DbHelper(ourContext); 
    ourDatabase = ourHelper.getWritableDatabase(); 
    return this; 
} 

public void close() { 
    ourHelper.close(); 
}

爲什麼不按照SQLCypher上的教程。發佈你的「之前」代碼似乎很懶惰。 – Booger 2014-11-10 14:17:11

之前初始化SQLiteOpenHelper子類中，你需要調用SQLiteDatabase.loadLibs(…);傳遞的上下文。這將適當地允許加載本地庫。
