I'm developing an Android app that use the java mongodb driver 3.0.3 to connect to every instance of mongodb.

The connector code to a generic istance is:

```
try{
    MongoCredential credential = MongoCredential.createCredential(user, dbname, pass.toCharArray());
    MongoClient mongoClient = new MongoClient( new ServerAddress(server , port ), Arrays.asList(credential));
    MongoDatabase db = mongoClient.getDatabase(dbname);
    System.out.println("Connect to database successfully ");
    Iterator i= mongoClient.listDatabaseNames().iterator();
    while (i.hasNext()){
        Log.d("DATABASE", (String) i.next());
    }
    Iterator ic= db.listCollectionNames().iterator();
    while (ic.hasNext()){
        Log.d("COLLECTION", (String) ic.next());
    }
}catch(Exception e){
    System.err.println( e.getClass().getName() + ": " + e.getMessage() );
}

```

At runtime I have some error:

> 
> 09-11 19:13:50.898 7418-7418/it.mysite.mongodbviewer W/org.bson.ObjectId﹕ Failed to get process identifier from JMX, using random number instead java.lang.NoClassDefFoundError: Failed resolution of: Ljava/lang/management/ManagementFactory;
>

> 

and 

> 
> com.mongodb.MongoException: java.lang.NoClassDefFoundError: com.mongodb.connection.ScramSha1Authenticator$ScramSha1SaslClient
> 
> 
> 

that generate a loop with this:

> 
> I/art﹕ Rejecting re-init on previously-failed class java.lang.Class
> 
> 
> 

Anyone has a solution?
java/lang/management/ManagementFactory seems not to exist for Android, how can you solve? If this is the center of the problem.

Thanks in advance, Matteo

PS: The complete log is:
