Question

I have built a project from the existing samples of bluetooth chat for android 2.3 I am aware that the the emulator does not support bluetooth.

较早我能够接手推器。这些职能是徒劳的,但我是在东部能够看到这一职能。我可以看到用户接口和所有内容。

But all of a sudden, today when I was trying the same app , I get an error saying bluetooth is not available and it quits.

我不知道是否有任何环境因错误而改变,但有些人能够帮助我做些什么。

Answer 1

you must have been using an earlier SDK version of the app that didn t check for absense of bluetooth support in the system....

I m 运行2.1 SDK版本的血清,并在那里检查。

你们有两个选择:

(1) 查阅并找到你以前用于先前的SDK的相同的示范守则,

(2) 进入法典(混合班级,Create()方法),并评论该法典:

    // Get local Bluetooth adapter
    mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();

    if (mBluetoothAdapter == null) {
        Toast.makeText(this, "Bluetooth is not available", Toast.LENGTH_LONG).show();
        finish();
        return;
    }

实际上,如果你只发表“定点()”一线,允许机器保持运行,同时仍然显示警告。
