android - SQLcipher(不同版本)在一个平台上工作，但在另一个平台上崩溃

Question

我在为 ARM/x86 设备构建 SQLcipher 时遇到奇怪的问题。

当我用 2.1.1 版本加密数据库并使用 Gradle for ARM 和 x86(胖客户端)构建它时，它在 ARM 设备上运行正确，但在 x86 上抛出错误

"No implementation found for native Lnet/sqlcipher/database/SQLiteDatabase;.native_key ([C)V"

当我对版本 2.2.2 重复之前的步骤时，它在 x86 上运行，但在 ARM 上它会抛出之前的错误。

3.1.0 版本的结果与 2.2.2 版本相同

你能帮我解决吗？

这是构建的 apk 文件(过滤后的 res 文件)的内容:

并且在 x86 设备上它可以正确打开数据库。

05-04 21:22:38.494    1849-1884/com.my.app D/DeviceID.db﹕ LastError

05-04 21:22:38.902    1849-1849/com.my.app D/cursor is﹕ net.sqlcipher.CrossProcessCursorWrapper@52aa7f30

这是我创建加密数据库的代码:

~/Soft/sqlcipher-2.1.1/sqlite3 db.sqlite "ATTACH DATABASE 'enc_v211.db' AS encrypted KEY '$dbkey';SELECT sqlcipher_export('encrypted');DETACH DATABASE encrypted;"
~/Soft/sqlcipher-2.2.1/sqlcipher db.sqlite "ATTACH DATABASE 'enc_v221.db' AS encrypted KEY '$dbkey';SELECT sqlcipher_export('encrypted');DETACH DATABASE encrypted;"
~/Soft/sqlcipher-3.1.0/sqlcipher db.sqlite "ATTACH DATABASE 'enc_v310.db' AS encrypted KEY '$dbkey';SELECT sqlcipher_export('encrypted');DETACH DATABASE encrypted;"

然后我将加密的数据库复制到 Assets 中，这是我打开数据库的代码:

 public void OpenDB() {     
        skg.logD(Thread.currentThread().getStackTrace()[2].getClassName() , Thread.currentThread().getStackTrace()[2].getMethodName()); 

        String dbname = "enc.db";
        String dbpath = "/data/data/com.my.app/databases/";
        try {
            InputStream myInput = context.getAssets().open(dbname);
            String outFileName = dbpath + dbname;
            OutputStream myOutput = new FileOutputStream(outFileName);
            byte[] buffer = new byte[1024];
            int length;
            while ((length = myInput.read(buffer)) > 0) {
                myOutput.write(buffer, 0, length);
            }
            myOutput.flush();
            myOutput.close();
            myInput.close();
        } catch (IOException e) {
            e.printStackTrace();
        }

        try {
            SQLiteDatabase.loadLibs(context);
            File databaseFile = context.getDatabasePath(dbpath + dbname);
            skg.logD("OtvorDB","getDBpath=" + databaseFile.toString());
            DID.context = context;
            database = SQLiteDatabase.openOrCreateDatabase(databaseFile, DID.db(), null);
            //database = SQLiteDatabase.openDatabase(databaseFile.getAbsolutePath(), DID.db(), null, SQLiteDatabase.NO_LOCALIZED_COLLATORS);
        } catch (Exception e) {
            e.printStackTrace();
            skg.logD("OtvorDB", e.getMessage() + e.toString() + e.getCause());
        }

正如您在代码中看到的，我尝试过使用 openDatabase，也尝试过使用 openOrCreateDatabase。

我用于测试的设备:

x86 - several devices in Genymotion VM

ARM - 2 real devices, android emulator
