尝试在 Android 中使用 Proguard 和 SQLcipher 时出现 NoClassDefFoundError

我得到了ava.lang.NoClassDefFoundError: net/sqlcipher/CursorWindow当尝试使用 sqlicipher 和 proguard 运行我的应用程序时。该项目在没有启用 proguard 的情况下可以完美运行。我第一次使用 sqlcipher 创建新数据库时出现上述错误。我查看了另一个看似相同的问题，但我尝试了该问题的答案，但仍然收到错误。

Android Proguard SqlCipher NoClassDefFoundError

这是我的全部proguard-properties:

我认为该类已被 Proguard Shrinking 工具删除。

尝试添加以下参数

-dontshrink

并告诉我是否有效。

我还发现 Sqlcipher 的受保护类中缺少一个属性：

: E/AndroidRuntime(18993): Caused by: java.lang.NoSuchFieldError: no field with name='nHandle' signature='I' in class Lnet/sqlcipher/database/SQLiteCompiledSql;

您还可以尝试保留 Sqlcipher 的受保护类吗？

-keep class net.sqlcipher.** {
    *;
}

P.S 您的配置中经常有选项 -dontobfuscate 吗？如果您保留它，您的应用程序将不会被混淆。
