Пара двух устройств bluetooth programaticaly

Question

Я делаю проект bluetooth, в котором я хочу спрятать два устройства Bluetooth в программном обеспечении в android.I использую api для api в android.It находит устройства. Но не возвращает Action_found намерение. условие для action_found намерения, оно возвращает false. Но в logcat он показывает найденные адреса устройств. Вот пример кода, который я попробовал. Может ли кто-нибудь удалить эту ошибку?

Заранее спасибо

Answer 1

Вы должны добавить правильное действие для фильтра mReceiver в! Вы должны были добавить: filter.addAction (BluetoothDevice.ACTION_FOUND);

BluetoothDevice.ACTION_FOUND не находится в фильтре, поэтому он никогда не принимается!

Так изменить эти строки:

IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED); 
registerReceiver(mReceiver, filter); 

к этому:

IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_DISCOVERY_FINISHED); 
filter.addAction(BluetoothDevice.ACTION_FOUND); 
registerReceiver(mReceiver, filter); 

Позвольте мне знать, если это сработало!
