Android 蓝牙在选项卡视图中强制关闭错误

Question

我正在实现一个基于 GPS 的室外定位器应用程序。

我使用 tabview，其中第一个选项卡中有地图和 GPS，第二个选项卡中有蓝牙连接。

在模拟器上，第一个选项卡工作正常，第二个选项卡我无法测试。

当我在 Android 设备上启动它时，应用程序被强制关闭，我收到此错误，我不知道应用程序出了什么问题。

任何帮助将非常感谢，

我在以下部分调用 listenUsingInsecureRfcommWithServiceRecord ：

public AcceptThread(boolean secure) {
        BluetoothServerSocket tmp = null;
        mSocketType = secure ? "Secure":"Insecure";

        // Create a new listening server socket
        try {
            if (secure) {
                tmp = mAdapter.listenUsingRfcommWithServiceRecord(NAME_SECURE,
                    MY_UUID_SECURE);
            } else {
                tmp = mAdapter.listenUsingInsecureRfcommWithServiceRecord(
                        NAME_INSECURE, MY_UUID_INSECURE);
            }
        } catch (IOException e) {
            Log.e(TAG, "Socket Type: " + mSocketType + "listen() failed", e);
        }
        mmServerSocket = tmp;
    }

Answer 1

可能的解决方案是应用 try-catch 块并尝试运行应用程序。

try{
public AcceptThread(boolean secure) { BluetoothServerSocket tmp = null; mSocketType = secure ? "Secure":"Insecure";
}
catch(Exception e){
e.printStackTrace();
}

另请检查您所拥有的设备的操作系统版本...

发生此致命异常的原因可能是您的设备操作系统版本较低，并且设备 ROM 中不存在该方法。
