使用 Android 的 Atlas mongodb时，我得到了NoClassDefFoundError。这是代码。
MongoClientURI uri = new MongoClientURI(
"mongodb://admin:xxx@clusterxxxx.mongodb.net:27017,clusterxxxx.mongodb.net:27017,clusterxxxx.mongodb.net:27017/test?ssl=true&replicaSet=Cluster0-shard-0&authSource=admin&retryWrites=true");
MongoClient mongoClient = new MongoClient(uri);
final MongoDatabase database = mongoClient.getDatabase("test");
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
MongoCollection < Document > collection = database.getCollection("col");
Document myDoc = collection.find().first();
Log.i("xxx", myDoc.toJson());
}
});
thread.start();
我正在使用以下驱动程序。
implementation 'org.mongodb:mongodb-driver:3.10.0'
这是错误消息。
