我编写的用于在启用蓝牙时禁用蓝牙的服务崩溃。

///////////////////////////////// 服务 //////////////// ///////////////

 public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub

            Intent startServiceIntent = new Intent(context, Bluetoothservice.class);
            context.startService(startServiceIntent);

            if(intent.getAction().equals(BluetoothAdapter.ACTION_STATE_CHANGED)){
                BluetoothAdapter bluetooth = BluetoothAdapter.getDefaultAdapter();
                if (bluetooth.getState() == BluetoothAdapter.STATE_ON
                        || bluetooth.getState() == BluetoothAdapter.STATE_TURNING_ON) {
                bluetooth.disable();
                }
                return;
            }

///////////////////////////////// 接收者 //////////////// ////////////////

@Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        // TODO Auto-generated method stub
        IntentFilter filterb = new IntentFilter(
                BluetoothAdapter.ACTION_STATE_CHANGED);
        BroadcastReceiver mreceiverb = new Broadcastreceiver();
        registerReceiver(mreceiverb, filterb);
        return super.onStartCommand(intent, flags, startId);

    }

任何人都可以帮忙吗？

您必须在单独的<uses-feature>元素中指定每个功能，因此如果您的应用程序需要多个功能，它将声明多个<uses-feature>元素。

例如，在设备中需要蓝牙和相机功能的应用程序将声明这两个元素：

<uses-feature android:name="android.hardware.bluetooth" />
<uses-feature android:name="android.hardware.camera" />

还要检查您是否已添加

 <uses-permission android:name="android.permission.BLUETOOTH">

BLUETOOTH   Allows applications to connect to paired bluetooth devices
BLUETOOTH_ADMIN Allows applications to discover and pair bluetooth devices

蓝牙功能的特殊处理

正如我在回答您的其他问题时所说，未经用户明确同意，您不应禁用蓝牙适配器。
