アプリからいくつかのBluetoothイベントを管理しようとしているため、ユーザーはアプリを離れる必要はありません& BluetoothデバイスをAndroid設定から検索/ペアリングしようとします。Androidのbluetooth BluetoothDevice.ACTION_FOUNDが起動されていませんか？
以前にペアになっているデバイスを列挙して検出を開始することはできますが、近くのデバイスは見つけられません。
背景情報：
デバイス=サムスンギャラクシーS6
OS =アンドロイド6.0.1、カーネル3.4.0-750027
Bluetoothデバイスは、Androidの独自の発見
に建て経由で表示されます私の関連コードは次のとおりです。
BroadcastRecieverのBluetoothDevice.ACTION_FOUNDがACTION_DISCOVERY_STARTED OR ACTION_DISCOVERY_FINISHEDが呼び出されているものの呼ば/トリガーされていません<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.BLUETOOTH" />

助けてください???

Android 6.0の下でアプリをテストするチャンスがありますか？ –
