最近需要加快wifi的扫描速度,所以使用了Iwlist和Iwconfig这两个工具。下载自:https ://github.com/nvamelichev/wireless-tools-android

编译后,我将这两个二进制文件以适当的权限放入 /system/xbin/。它在“终端模拟器”的应用程序上运行良好,但是当我尝试在我自己的应用程序中执行它们时。它不起作用....这是我的代码:

        iwProcess = Runtime.getRuntime().exec("iwlist --version");
        BufferedReader reader = new BufferedReader(new InputStreamReader(
                iwProcess.getInputStream()));
        int read;
        char[] buffer = new char[4096];
        StringBuffer output = new StringBuffer();

        while ((read = reader.read(buffer)) > 0) {
            output.append(buffer, 0, read);
        }
        reader.close();
        iwProcess.waitFor();

        String nativeOutput = output.toString();
        mTextView.setText(nativeOutput);
        StringBuffer sb = new StringBuffer();

        BufferedReader br = new BufferedReader(new InputStreamReader(
                iwProcess.getErrorStream()));
        while ((read = br.read(buffer)) > 0) {
            sb.append(buffer, 0, read);
        }
        br.close();
        mTextView.setText(output + sb.toString());

结果是“协议不支持的套接字地址系列”真的让我感到困惑......
