如何将Mongo DB与Android应用程序连接起来

我在Eclipse中生成了Android项目，一切正常。 我添加了几个按钮等事件。 现在，我正在尝试创建Mongo对象，但它会抛出错误。 你有任何解决方案吗？ 可以连接这两个吗？

Answer 1

此驱动程序不支持Android。 jira有一个未解决的问题。

Answer 2

我知道这是一个老post，但我只是想分享我的Android + MongoDB驱动程序体验。

首先，IT工作！

事实certificate，parvin提到的问题已得到修复和结束。

但是，当你使用最新版本（写作时为2.11.3）时，你会发现一个非常可怕的错误是自我呈现，但不要担心 – 驱动程序仍在工作。 至少我能够进行身份validation和插入数据。

您将看到的错误如下所示：

 I/dalvikvm(17945): Could not find method java.lang.management.ManagementFactory.getRuntimeMXBean, referenced from method org.bson.types.ObjectId. W/dalvikvm(17945): VFY: unable to resolve static method 7096: Ljava/lang/management/ManagementFactory;.getRuntimeMXBean ()Ljava/lang/management/RuntimeMXBean; D/dalvikvm(17945): VFY: replacing opcode 0x71 at 0x0071 I/dalvikvm(17945): Could not find method java.lang.management.ManagementFactory.getPlatformMBeanServer, referenced from method com.mongodb.util.management.jmx.JMXMBeanServer. W/dalvikvm(17945): VFY: unable to resolve static method 7095: Ljava/lang/management/ManagementFactory;.getPlatformMBeanServer ()Ljavax/management/MBeanServer; D/dalvikvm(17945): VFY: replacing opcode 0x71 at 0x0003 E/dalvikvm(17945): Could not find class 'javax.management.ObjectName', referenced from method com.mongodb.util.management.jmx.JMXMBeanServer.createObjectName ... etc. more scary stuff ... 

我的工作代码如下所示：

 MongoClient mongo = new MongoClient(ip, port); DB db = mongo.getDB("myDatabase"); boolean auth = db.authenticate(username, password); if (auth) { DBCollection collection = db.getCollection("myCollection"); DBObject jsonData = (DBObject) JSON.parse(jsonString); collection.insert(jsonData); } 

我希望这有助于某人，因为我对错误感到非常困惑。

我同意Phil它确实有效，但它似乎再次打破和关闭，如果你需要找到更多最新的库，请查看以下内容

对于那些需要最新预编译JAR文件的人来说，最新的Java驱动程序的快照

如果你想要源代码，那么请查看GIT Source Repository并链接到最新的stable等
