Androidアプリをローカルホストのcouchbaseサーバーに接続しようとしています。データベースとマネージャーを次のように初期化しました。データベースを初期化した後、タイプデータベースのパラメーターを受け入れるstartSync()関数を呼び出しています
public static final String DB_NAME = "firstdb";
public static final String TAG = "firstdb";private void helloCBL() {
Manager manager = null;
Database database = null;
try {
manager = new Manager(new AndroidContext(this), Manager.DEFAULT_OPTIONS);
database = manager.getDatabase(DB_NAME);
database.addChangeListener(this);
startSync(database);
} catch (Exception e) {
Log.e(TAG, "Error getting database", e);
return;
}
}
これは startSync() 関数です
protected void startSync(Database database) {
URL syncUrl;
try {
syncUrl = new URL("http://10.0.2.2:4984/firstdb");
} catch (MalformedURLException e) {
throw new RuntimeException(e);
}
Replication pullReplication = database.createPullReplication(syncUrl);
pullReplication.setContinuous(true);
Replication pushReplication = database.createPushReplication(syncUrl);
pushReplication.setContinuous(true);
pullReplication.addChangeListener(this);
pushReplication.addChangeListener(this);
// start both replications
pullReplication.start();
pushReplication.start();
}
しかし、私のlogcatは次のようにエラーが発生します：AndroidアプリでURLを使用することについて混乱しています

これらのエラーは、Android デバイスでアプリケーションを実行すると発生します。エミュレータでアプリケーションを実行すると、エラーには何も表示されませんが、詳細なメッセージが表示されます
