CWAC Saferoom 和代码压缩,如何在拥有 Saferoom 的同时压缩我的代码? [固定的]
CWAC Saferoom and Code Shrinking, How do I shrink my code while having Saferoom? [FIXED]
我需要帮助使用 CWAC Saferoom 实施 android 的 R8 代码收缩器。
两者都实现良好并在调试模式下进行了测试,但是当我生成发布 APK 时出现此堆栈跟踪并且应用程序崩溃:

我相信我遗漏了一些东西,可能在 proguard 文件中排除了 saferoom 的包(如果我使用 proguard),或者在压缩我的代码时我是否必须在我的依赖项中添加 SQLCipher 库,如果没有,我是完全没有想法。
注意:
- 出于隐私原因,我更改了应用程序 ID 和堆栈跟踪 ID
- 我的问题只发生在我生成发布 APK 时,另一方面,SQLCipher 数据库很好并且实现良好
应用程序的构建 gradle

}
解决方案:
根据@commonsware,将以下内容添加到您的 proguard 文件中(无论您使用 Android R8 还是 proguard),它应该可以工作:
-keep class net.sqlcipher.** { *; }
-keep class net.sqlcipher.database.* { *; }
基于this issue,将此添加到您的 ProGuard 保留规则中:
-keep class net.sqlcipher.** { *; }
-keep class net.sqlcipher.database.* { *; }
