java - 适用于 Android 的 SQLCipher : couldn't find native method

转载作者：行者123 更新时间：2023-12-01 12:50:10

我正在尝试使用 SQLCipher 库，但总是遇到相同的错误。我有一个很小的类(class)来测试该库:

import android.database.Cursor;

// Uncomment to use sqlite
//import android.database.sqlite.SQLiteDatabase;
//import android.database.sqlite.SQLiteOpenHelper;

// Uncomment to use sqlcipher
import net.sqlcipher.database.SQLiteDatabase;
import net.sqlcipher.database.SQLiteOpenHelper;

import android.content.ContentValues;
import android.content.Context;
import android.util.Log; 

public class DataHandler extends SQLiteOpenHelper {

  SQLiteDatabase db;
  String dbPassword;  

  static final String dbName = "demo.db";
  static final String defualtDbPassword = "password";  
  static final boolean ENCRYPT_DATA = false;
  static final int dbVersion = 1;

  public DataHandler(Context context){
    this(context, defualtDbPassword);
  }

  public Z41DataHandler(Context context, String password){
    super(context, dbName, null, dbVersion);

    dbPassword = password;

    // Uncomment to use sqlite
//  db = getWritableDatabase();

    // Uncomment to use sqlcipher   
    SQLiteDatabase.loadLibs(context);
    db = getWritableDatabase(dbPassword);
  }

...
...    
Other methods to perform queries to the database
...
...    

}

如您所见，代码已准备好与标准 SQLite 库和 SQLCipher 一起使用，具体取决于注释的行。

当我使用 SQLite 测试该类时，它在模拟器中正常工作:数据库已创建，我可以执行 INSERT、UPDATE 或 SELECT 操作。

当我尝试使用 SQLCipher 库时出现问题。在尝试任何操作之前，我收到以下错误:

我尝试使用 SQLCipher 版本 3.1(Android 的最新可用二进制文件)、2.2.2 和 2.1.1 来执行此测试，并且始终得到相同的结果。我无法在真实设备上测试它，因为缺乏它。

我已按照说明将库包含在我的项目中:复制 libs 和 asset 文件夹的内容并将库包含在构建路径中:

如果我打开 adb 终端并移动到应用程序文件夹，我可以看到 lib 文件夹，其中包含 libdatabase_sqlcipher.so、libsqlcipher_android.so 和 libSTLport_shared.so

顺便说一下，我使用的是适用于 Mac 的 ADT v22.6.2-1085508。

知道会发生什么吗？

最佳答案

我在 Android Studio 上遇到了类似的问题。原来我在“主”目录中缺少“jnilibs”文件夹。

Example of the Directory Structure

添加后，进行干净的构建并尝试再次运行该项目。
