Java 连接到mongoDB的代码错误，无法识别导入的jar

Java 连接到mongoDB的代码错误，无法识别导入的jar,java,android,eclipse,mongodb,maven,Java,Android,Eclipse,Mongodb,Maven,我正在尝试连接到mogoDB数据库，我安装了mongoDB，如中所述在ubuntu终端上通过mongoshell玩mongo，一切都很精明，然后我尝试在android应用程序中实现它。我参考了本教程并对其进行编辑以创建下面列出的我的代码包com.example.test1 import java.net.UnknownHostException; import java.text.MessageFormat; import java.util.Set; import android.

我不认为你可以从android内部使用MongoDb。请参阅此链接

您所指的链接，即，是从java应用程序而不是从android内部工作

我认为您的解决方案是，如果您希望在android设备中安装数据库，可以使用sqlite或couchbase，或者您可以在服务器中安装MongoDb数据库（或使用类似的数据库），并从安装在web服务器中的web服务调用此MongoDb数据库。所以设计可以是这样的。

您的android应用程序-->调用web服务-->调用Mongodb

尝试将jar复制到eclipse项目中的libs文件夹，然后重新添加它，提供您计算机的ip，而不是本地主机。好的，但是，我想知道我的应用程序中发生错误的原因是什么？如果我至少导入jar文件，应用程序应该编译ri8？这里的错误甚至在应用程序运行之前就发生了，所以我猜测我下载的java mongo驱动程序不支持android？我想你是对的，MongoDb驱动程序现在支持android，但我仍然不知道这是否是个好主意。看看这些链接。当您像import com.MongoDb.DBCollection一样放置MongoDb导入时；您看到这些导入中的错误了吗？我没有这样做，lemme checki做了，所有的错误都消失了，现在它正在编译和运行，但是异常正在发生
