service中启用广播失效，无法使用

Question

public class Myservice extends Service {
    private BluetoothAdapter bTAdatper;
    @Nullable
    @Override

        return null;

Answer 1

没log？没报错？
或者版本低的手机能运行么？

Answer 2

while (bTAdatper.isDiscovering()) {  <-----这里一直是false，没往下走，就是没有开始蓝牙搜索，接受不到广播，如果已经开始了搜索，bTAdatper.isDiscovering()=true,那循坏不是一直走？
                    System.out.println("11");
                    try {
                        Thread.sleep(1000);
                        bTAdatper.startDiscovery();
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
不需要搞1秒延时， initReceiver();之后
if(!bTAdatper.isDiscovering()){ //判断没有在搜索就开始走索蓝牙
bTAdatper.startDiscovery();
}

Answer 3

我按照您说的重新改了一下，链接:https://pan.baidu.com/s/10n5tQQJeRNk5kJE4VNX-Lw 提取码:36s0，但是还是有问题，可以帮我看看吗

Answer 4

Application中注册广播？没见过这种操作，放到Service中吧
另外，要会打日志断点调试找问题出现在哪里

Answer 5

 https://bbs.csdn.net/topics/394907454帮我看看这个好吗，我在service中搜索蓝牙，但是只能开始搜索和搜索完毕，不能发现设备

Answer 6

   BlueToothReceiver receiver = new BlueToothReceiver();
        registerReceiver(receiver, makeFilter());  @RequiresApi(api = Build.VERSION_CODES.JELLY_BEAN_MR2)
    private void startSearch() {        if (bluetoothAdapter == null) {
            Logger.d("gxh", "device not support bluetooth");
            swipeRefreshLayout.setRefreshing(false);
            return;
        }        //判断蓝牙是否开启
        if (bluetoothAdapter.isEnabled()) {
            if (bluetoothAdapter.isDiscovering()) {
                bluetoothAdapter.cancelDiscovery();
            }
            deviceMap.clear();
            bluetoothAdapter.startDiscovery();
        } else {
            Intent enabler = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
            startActivityForResult(enabler, 100);
        }    }
 public class BlueToothReceiver extends BroadcastReceiver {        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();            if (BluetoothDevice.ACTION_FOUND.equals(action)) {
                BluetoothDevice device = intent
                        .getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
                deviceMap.put(device.getAddress(), device);
                Logger.d("gxh", "found:" + device.getName());
            } else if (BluetoothAdapter.ACTION_DISCOVERY_FINISHED.equals(action)) {
                //搜索完毕
                Logger.d("gxh", "ACTION_DISCOVERY_FINISHED");
                swipeRefreshLayout.setRefreshing(false);
                devices.clear();
                for (Map.Entry<String, BluetoothDevice> entry : deviceMap.entrySet()) {
                    devices.add(entry.getValue());
                }
                blueConfigAdapter.setNewData(devices);
            }
        }
    }
  public IntentFilter makeFilter() {
        IntentFilter filter = new IntentFilter();
        filter.addAction(BluetoothAdapter.ACTION_STATE_CHANGED);//蓝牙状态改变的广播
        filter.addAction(BluetoothDevice.ACTION_FOUND);//找到设备的广播
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_FINISHED);//搜索完成的广播
        filter.addAction(BluetoothAdapter.ACTION_DISCOVERY_STARTED);//开始扫描的广播
        filter.addAction(BluetoothDevice.ACTION_BOND_STATE_CHANGED);//状态改变
        return filter;
    }
这是我以前写的，可以用。
