使用SQLCipher库时出现不满意的链接错误

Question

我正在使用Android的SQLCipher库来加密/解密DB文件.我遵循API中讨论的添加库的确切步骤.

但是当我运行项目时,我收到一个不满意的链接错误...这是logcat ...

请给我任何参考或提示.

Answer 1

java.lang.UnsatisfiedLinkError 在使用之前未初始化SQLCipher库时发生.

要解决此问题,请SQLiteDatabase.loadLibs(this);在使用前致电.

例如:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    SQLiteDatabase.loadLibs(this);

    // Set up the window layout
    setContentView(R.layout.main);

    //instance of database adapter
    db = DBAdapter.getInstance(this);

    //load database
    db.load("password goes here");

您需要将 .so 文件添加到 Eclipse 项目的 libs/armae​​bi 文件夹中并重建。
