Question

我尝试在Android 4.2.2上启动项目时遇到问题。这是堆栈跟踪：

08-06 11:00:50.041: E/AndroidRuntime(10606): Caused by: net.sqlcipher.database.SQLiteException: not an error
08-06 11:00:50.041: E/AndroidRuntime(10606):    at net.sqlcipher.database.SQLiteDatabase.dbopen(Native Method)

这在Android 4.0.4上运行良好，但是当我在Android 4.2上启动时，所有时间都崩溃了。我在官方网站上提供了sqlcipher的来源，我希望这是我采取的最后一个来源（名称是SQLCipher + for + android + 2.2.0），我没有看到这个项目的最新版本。

提前感谢您的回答（我希望这不是一个重复问题导致我搜索并且找不到答案...）

最终有效。为此，我只需将greenDao替换为net.sqlcipher的所有导入库android.database然后我在.jar中导出这个新的greenDao我带SQLCipher.jar不要忘记导入commons-codec.jar和guavra-r09.jar plus来自SQLCipher的文件夹armeabi和文件夹x86以及文件夹资产中的文件icudt46l.zip。

在我的情况下，我有一个包含SQLCipher的项目daocore，并且依赖于我的项目Android依赖于那个在Android 4.1中工作的daocore项目，而不是4.2以及更多，所以问题是项目之间的依赖关系不知道为什么，但是如果你在所有Android中的源项目中导入所有这就是它。

在版本android 4.2.2上使用sqlcipher的Android错误
