Java Android 4.2.2版上的sqlcipher出现Android错误

Java Android 4.2.2版上的sqlcipher出现Android错误,java,android,android-4.0-ice-cream-sandwich,android-4.2-jelly-bean,sqlcipher,Java,Android,Android 4.0 Ice Cream Sandwich,Android 4.2 Jelly Bean,Sqlcipher,当我尝试在Android 4.2.2上启动我的项目时,我遇到了一个问题。 以下是stacktrace: 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.

当我尝试在Android 4.2.2上启动我的项目时,我遇到了一个问题。 以下是stacktrace:

最后,这就是工作。为此,我只需使用greenDao将所有导入库android.database替换为net.sqlcipher,然后将这个新的greenDao导出到.jar中,我使用sqlcipher.jar,不要忘记从sqlcipher导入commons-codec.jar和guavra-r09.jar,以及文件夹armeabi和文件夹x86,并在文件夹资产文件icudt46l.zip中


在我的例子中,我有一个包含SQLCipher的项目daocore,它是依赖性的,我的项目Android依赖于在Android 4.1及以下版本中工作的daocore项目,但不是在4.2及以上版本中工作的daocore项目,所以问题是项目之间的依赖性,我不知道为什么,但如果你导入源项目中的所有内容,这在所有Android系统中都能工作,那就是了。

尝试升级到适用于Android 2.2.1的SQLCipher。我尝试过,但这会导致与具有相同堆栈的版本2.2.0相同的错误。如果有助于您理解的话,我可以给出部分代码。在这里发布一些源代码,或者更好地创建一个可复制的测试用例。通过我的编辑,您可以获得代码通过的所有状态。如果您需要更多信息,请告诉我,非常感谢您在这个问题上的考虑和帮助。这似乎非常复杂,没有明显的好处。请尝试升级到适用于Android 2.2.1的SQLCipher。我尝试过,但这让我遇到了与具有相同堆栈的版本2.2.0相同的错误。如果有助于您理解的话,我可以给出部分代码。在这里发布一些源代码,或者更好地创建一个可复制的测试用例。通过我的编辑,您可以获得代码通过的所有状态。如果你需要更多的信息,请告诉我,非常感谢你在这个问题上的考虑和帮助,我非常感激。这看起来非常复杂,没有明显的好处。
