私は現在、Androidアプリに取り組んでいます。Polar Wearlink ベルトを Bluetooth 経由で携帯電話にペアリング (または接続) する必要があります。

私は複数のウェブサイトやトピックを試しましたが、何かを試すたびに強制的に閉じられます.

これが私の最後の試みです：

public class BluetoothConnectionManager {

// Context
private Context c;

// Bluetooth adapter
private BluetoothAdapter btAdapter;

// Bluetooth device
private BluetoothDevice device;

// Dialog
private AlertDialog dialogDetected;

public BluetoothConnectionManager(Context cont, BluetoothDevice dev, BluetoothAdapter ba){
    c = cont;
    device = dev;
    btAdapter = ba;

}


public void start() {
    ConnectThread ct = new ConnectThread(device);
    ct.run();
}

private class ConnectThread extends Thread {
    private final UUID MY_UUID = UUID.randomUUID();
    private final BluetoothSocket mmSocket;
    private final BluetoothDevice mmDevice;

    public ConnectThread(BluetoothDevice device) {
        BluetoothSocket tmp = null;
        mmDevice = device;
        try {
            tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
        } catch (IOException e) { }
        mmSocket = tmp;
    }

    public void run() {
        btAdapter.cancelDiscovery();
        try {
            String tag = "text";
            Log.d(tag ,"FORCE CLOSE HERE");
            mmSocket.connect();
        } catch (IOException connectException) {
            try {
                mmSocket.close();
            } catch (IOException closeException) { }
            return;
        }
        manageConnectedSocket(mmSocket);
    }

    public void cancel() {
        try {
            mmSocket.close();
        } catch (IOException e) { }
    }
}
