近期公司有蓝牙设备项目，遇到个问题；

连接蓝牙设备的app在连接时，如遇到蓝牙设备的信号名称错误或蓝牙设备关闭时，app有一定概率出现程序闪退；

经查证原因出现在接收蓝牙信号的广播的地方，原代码如下：

public BroadcastReceiver mReceiver = new BroadcastReceiver() {


@Override

public void onReceive(Context context, Intent intent) {


//g_Context.unregisterReceiver(this); —deleted by jerry

String action = intent.getAction();

String strDevName = new String();

if ( BluetoothDevice.ACTION_FOUND.equals(action) ) {


BluetoothDevice device = intent

.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);

strDevName = device.getName();

if ( strDevName.equalsIgnoreCase(bt_Name)) {


if( mBluetoothAdapter != null
