私は正常に発見してピアに接続するwifidirectアプリを持っています。私が開発している別のアプリにそのアプリを「添付」しました。 Wifidirectを使ってロボットをブルートゥースで制御すると同時にそのアプリケーションには「再生ボタン」があり、クリックすると別のアクティビティに移動し、そのアクティビティには2つのフラグメントがあり、1つが最初に表示されます"プレイ"ボタンをクリックして、ユーザーがピアに接続することを義務づけた後（それは私がwifidirectアプリを添付していた）、それを接続した後、このフラグメントはゲームインターフェイスを持ち、ロボットの接続と制御）。Wifidirectディスカバリーがピアを見つけられない
要約：最初のアクティビティには再生ボタンがあり、ボタンをクリックすると、2つのフラグメントで2番目のアクティビティに移動します。第2のアクティビティは、Wifidirectのピアに接続しなければならず、その後はブルートゥースを使用してロボットを接続して制御する必要があります。第二の活動で
（私が知っている...混乱）を同時にWifiDirectとBluetoothコミュが起こっている
私の問題：私はもっぱらWifidirectアプリを使用している場合は、それが捜しますとsucessfully接続しているけど」と両方のアプリの "融合"を、それは何も発見せずに永遠に検索します。何が起こっているのアイデア？多分コミュニケーションや同じ活動の中で起こっている多くの事に？私が混乱している場合は教えてください。
