先附上SDK中关ACTION_LOCAL_NAME_CHANGED的说明:
Broadcast Action: The local Bluetooth adapter has changed its friendly Bluetooth name.
This name is visible to remote Bluetooth devices.
Always contains the extra field EXTRA_LOCAL_NAME
containing the name.
Requires BLUETOOTH
to receive.
Constant Value: "android.bluetooth.adapter.action.LOCAL_NAME_CHANGED"
最近开发蓝牙相关APP的时候发现了一个现象:启动蓝牙时候系统也会发布ACTION_LOCAL_NAME_CHANGED这个广播,而此时并没有使用APP中的重命名蓝牙适配器的功能。这就可能会给自身APP中的广播接收器带来一些误操作,因此需要在进行相关操作前进行一个判断操作,广播接收部分代码段如下:
public void onReceive(Context c, Intent i)
{
switch (i.getAction())
{
case BluetoothAdapter.ACTION_LOCAL_NAME_CHANGED:
{
//必须先进行此层if判断避免启动时的误判断
if(mBluetoothStateManager.BluetoothStateManger_getBluetoothAdapter().isEnabled())
{
System.out.println("Name has changed!\n");//可替换成你想要的响应操作
}
}break;
default:break;
}
}
